Rising nuclear risk, disarmament and the Nuclear Non-Proliferation Treaty Contents

Chapter 3: The NPT and the wider non-proliferation regime

The NPT and its bargain

89.Mr Plant said the NPT was “a security bargain between states that wanted to see the Nuclear Weapon States disarm but also did not want their neighbours to become nuclear states.”137 Ms Cox described the “fundamental bargain” of the NPT to be that all states “work to prevent the spread of nuclear weapons”, “work towards disarmament” and in return “all states can access the benefits of the peaceful uses of nuclear energy.”138

90.Box 2 describes the NPT.

Box 2: Treaty on the Non-Proliferation of Nuclear Weapons (NPT)

The NPT was opened for signature in 1968 and entered into force in 1970. It was extended indefinitely in 1995. 191 states have joined the NPT. It has been ratified by more countries than “any other arms limitation and disarmament agreement”.139

The treaty recognised the five existing Nuclear Weapon States at the time it was signed—Russia, the US, the UK, France and China. All five are States Parties to the NPT,140 although France and China did not become States Parties until 1992. The UK, the US and Russia (formerly the Soviet Union) are the depositary governments of the NPT.141

India, Israel, Pakistan and South Sudan have not signed the NPT. In 2003 North Korea announced its withdrawal.142

The NPT contains “the only binding commitment in a multilateral treaty to the goal of disarmament by the Nuclear Weapon States”.143 Article 6 sets out that “Each of the Parties to the Treaty undertakes to pursue negotiations in good faith on effective measures relating to cessation of the nuclear arms race at an early date and to nuclear disarmament, and on a treaty on general and complete disarmament under strict and effective international control.”144

There is a safeguards system to verify compliance through inspections, managed through the International Atomic Energy Agency (IAEA).145

The provisions of the NPT envisage a review of its operation every five years. This was reaffirmed by the States Parties at the 1995 NPT Review and Extension Conference.146 The next Review Conference will be held in 2020. Preparatory Committees are held in the three years running up to each Review Conference;147 the next will be in New York from 29 April to 10 May 2019.148

The pillars of the NPT

91.Dr Christopher Ford, Assistant Secretary, Bureau of International Security and Nonproliferation, US Department of State, told us that it had “become commonplace … to speak of the NPT as having ‘three pillars’—that is, three explicitly or implicitly coequal elements in the form of non-proliferation, disarmament, and the peaceful uses of nuclear technology”. However, a “‘three pillars’” formulation was “not intrinsic to the Treaty or part of its original understanding”.149 This “imagery of ‘three pillars’ misleads because it tends to suggest coequality”; it was “quite profoundly mistaken, not to mention dangerous to the health of the NPT regime.” The “conceptual and structural core of the NPT is non-proliferation, and this is the foundation upon which rest the two supported ‘structures’ of nuclear disarmament and peaceful uses”.150

92.Ms Price held a similar view: while there were “other pillars”, which were “part of the bargain”, “the original concept of the treaty is one of non-proliferation”. The pillar on peaceful uses was “the quid pro quo, or benefits, for the planet and humanity that come from having” non-proliferation.151

93.Other witnesses disagreed with Dr Ford. The United Nations Association-UK (UNA-UK) said that “Contesting the co-equality of the pillars of the NPT is factually incorrect—all articles of the treaty are equally legally binding.” The assertion was “irreconcilable with UN guidance”.152 Paul Ingram, Executive Director, BASIC, said the NPT was called a non-proliferation treaty “because it is both vertical and horizontal153 … Vertical non-proliferation is essentially disarmament, so this is both a disarmament and a non-proliferation treaty. I do not think we can see one as more important than the other.”154

94.Dr Lyndon Burford, Postdoctoral Research Associate, Department of War Studies, King’s College London, said the UK’s “failure to affirm the equal importance of the pillars constitutes a step backwards from a long-standing norm of support for disarmament and peaceful uses in UK policy statements, and in joint statements by the European Union (EU) and the NPT Nuclear Weapon States which the UK has explicitly endorsed.”155

95.Mr Ingram said that it was necessary to demonstrate “good will on disarmament” in order to have “moral, legal or any other basis … to convince other states that they need to engage seriously in non-proliferation measures”.156 Ms Nakamitsu said that the UN Secretary General considered disarmament and non-proliferation to be “two sides of the same coin”: “We cannot continue to hold non-proliferation obligations unless we also continue to make progress on disarmament obligations.”157

96.The UK should stand by its commitment, as a signatory of the Nuclear Non-Proliferation Treaty and one of its three depositary powers, to implementing commitments across all three pillars of the NPT—non-proliferation, peaceful uses of nuclear technology and disarmament.

The wider regime

97.The NPT is the “core” of a wider non-proliferation regime.158 It is supported by “a complex web of dozens of international institutions and agreements to prevent the spread of nuclear weapons”.159 The principal elements of the wider regime are set out in Box 3.

Box 3: The wider regime


The IAEA was established in 1957 through the IAEA Statute. It reports to both the UN General Assembly and Security Council. It has “the mandate to work with its Member States and multiple partners worldwide to promote safe, secure and peaceful nuclear technologies”.160 The IAEA describes its role in the nuclear non-proliferation regime as “a confidence-building measure, an early warning mechanism, and the trigger that sets in motion other responses by the international community if and when the need arises”.161

Each Non-Nuclear Weapon State Party to the NPT concludes a standard safeguards agreement with the IAEA, INFCIRC/153 (Corrected),162 “with a view to preventing diversion of nuclear energy from peaceful uses to nuclear weapons or other nuclear explosive devices,”163 to comply with article 3 of the treaty.164

The voluntary Additional Protocol to the safeguards agreement, approved in 1997, “provides additional tools for verification”.165 It enables the IAEA “to achieve confidence as to the absence of undeclared materials or activities in a given state”. This usually follows “several years of gathering information, inspecting locations, and analysing data”.166 As of December 2018, Additional Protocols are in force with 134 States and Euratom. Another 16 States have signed an Additional Protocol but have yet to bring it into force. One State provisionally applies an Additional Protocol to its comprehensive safeguards agreement, pending its entry into force.167 Some States Parties to the NPT which use nuclear energy, including Brazil, have not signed or ratified an Additional Protocol.168The five Nuclear Weapon States are not required to have IAEA safeguards agreements under the NPT. They have all signed voluntary offer safeguards agreements, which permit the IAEA to apply safeguards to material in select eligible facilities. This covers civilian nuclear material and sites. All five Nuclear Weapon States have also concluded Additional Protocols to these voluntary offer safeguards agreements.169

The Nuclear Suppliers Group (NSG)

The Nuclear Suppliers Group is “a group of nuclear supplier countries that seeks to contribute to the non-proliferation of nuclear weapons through the implementation of two sets of Guidelines for nuclear exports and nuclear-related exports.”170 It “seeks to strengthen the non-proliferation regime, with the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) as its legal foundation.”171

It has 48 participating governments.172

The NSG was founded in response to India’s nuclear test in 1974.173 Its Guidelines are “sets of conditions of supply that are applied to nuclear transfers for peaceful purposes to help ensure that such transfers will not be diverted to unsafeguarded nuclear fuel cycle or nuclear explosive activities”. They are not legally binding, but participating governments “commit to apply those Guidelines via their national legislation”.174

The Conference on Disarmament

The Conference on Disarmament is “the single multilateral disarmament negotiating forum of the international community”. Its terms of reference “include practically all multilateral arms control and disarmament problems”. It has 65 members. It meets in an annual session, with a rotating presidency of four weeks’ duration.175 It is discussed further in Chapter 4.

UNSC resolutions

UN Security Council Resolutions form part of the nuclear non-proliferation regime. Notable resolutions include Resolution 984 (1995) on security assurances,176 Resolution 1540 (2004) on preventing the acquisition of weapons of mass destruction by non-state actors,177and Resolution 1325 (2000) on women, peace and security. 178

Other elements of the regime

Other international initiatives that can be regarded as part of the wider regime include:

  • Other prospective non-proliferation and disarmament treaties, including the Comprehensive Nuclear-Test-Ban Treaty and a fissile material cut-off treaty (discussed in Chapter 4);
  • Bilateral arms control treaties (discussed in Chapter 4);
  • P5 talks on nuclear issues;
  • Nuclear security summits (initiated by the Obama Administration);
  • Negative security assurances by nuclear-weapon states (see Chapter 2);
  • Other treaties and conventions such as the Outer Space Treaty and treaties and conventions prohibiting or limiting weapons and military activities, including biological and chemical weapons, landmines and cluster munitions;179 and Nuclear-free zones, which are discussed later in this chapter.
  • Verification and safeguards

    The IAEA

    98.The role of the IAEA is set out in Box 3. The FCO said that IAEA safeguards were “a fundamental component of nuclear non-proliferation.”180 Dr Hobbs said that the IAEA played “a crucial role in supporting states to develop provisions on nuclear security—providing international guidance, training and support services upon request—including physical protection upgrades, the removal of high-risk materials and the strengthening of security culture.”181

    Disarmament verification

    99.Dr Rafael Grossi, Permanent Representative of Argentina to the International Organisations in Vienna and President-designate of the 2020 NPT Review Conference, said that beyond the “grandiosity of getting rid of nuclear weapons” was the need for “complicated” technical work on verification. When Nuclear Weapon States decide to disarm, this process would need to be verified “through a … circle of inspectors”. He said it was not unusual for such technical work to precede political decisions.182

    100.Verification is a sensitive issue: the FCO said such a process needed to give confidence “that a nuclear-armed state has dismantled its warheads in a way that makes us safer, rather than in a way that proliferates nuclear weapons knowledge, and that such dismantlement is permanent and verifiable”.183 There is also sensitivity for Nuclear Weapon States in working with Non-Nuclear Weapon States without contributing to proliferation.

    101.Dr Grossi said there had “been progress in tackling, or starting to tackle, the technical issues, the methods, the sequences, the technologies, the non-proliferation barriers that you have to set up in order to have a truly multinational inspectorate dealing with nuclear disarmament verification”. This technical work was needed in preparation for a time when disarmament was on the agenda.184

    102.Dr Roberts cautioned that while work on verification technologies was “important” and helped with monitoring and enforcement, there was still no “compliance mechanism that would allow the nuclear-armed states confidently to disarm and [assure] all states that no militarily-significant cheating would go undetected and unchecked”.185

    Disarmament verification work by the UK

    103.Ms Price said the UK had “been doing very practical work to demonstrate what is possible and how difficult disarmament verification is”.186 There are four aspects to this work.

    104.First, the FCO said the UK and Norway had worked together since 2007 on “the first ever technical project between a Nuclear and Non-Nuclear Weapon State in this field”.187 The UK–Norway Initiative works to investigate “the technical and procedural challenges of verifying possible future nuclear disarmament and arms control agreements”.188

    105.Second, the UK participated in the Quad Initiative with the US, Norway and Sweden.189 This had grown out of the UK–Norway Initiative and verification and arms control exercises between the UK and the US.190 The Quad Initiative had undertaken “the first ever multilateral disarmament verification exercise”, at RAF Honington in October 2018. This exercise “brought a new level of realism to such exercises by using our former nuclear weapons storage area”.191

    106.Third, Ms Price said there was a UN group of government experts on verification with which the UK was engaged.192

    107.Fourth, the UK contributed to the International Partnership for Nuclear Disarmament Verification (IPNDV). The IPNDV is an initiative including more than 25 countries with and without nuclear weapons, which works to identify challenges associated with nuclear disarmament verification and develop potential procedures and technologies to address them.193 The UK had “hosted the IPNDV’s plenary session” and was “very involved in many of the practical working groups”.194

    108.Witnesses praised the UK’s work on verification, in partnership with other countries such as Norway, Sweden, the US and China.195 Dr Ritchie said the UK’s “valuable and important work” on verifying the dismantlement of nuclear warheads had been “rolled into the wider [US] State Department programme”.196

    109.Witnesses had a number of proposals for further UK work in this area. First, Mr Plant suggested the UK should increase “its financial commitment to arms control verification”.197 Second, it should increase its political commitment to this work. He said the UK “devotes a lot of attention to nuclear warhead dismantlement verification … against the day when a great breakthrough is made”. He thought it “more practical to think about technologies that could verify the next arms control treaty”, work that the UK was not undertaking at present.198

    110.A third suggestion, from Dr Hassan Elbahtimy, Lecturer in Science and Security, King’s College London, was for the UK to address “ some of the practical questions”, such as how to reduce the number of nuclear weapons and “build up confidence” that disarmament was happening.199

    111.Fourth, witnesses suggested further international co-operation, with China and Middle Eastern countries. Dr Nicola Leveringhaus, Lecturer, War Studies Department, King’s College London, suggested that the UK should “engage China in a separate verification process, perhaps linked to the UK–Norway initiative, or its successors, with a view to understanding China’s position on verification matters beyond its borders”. China had “displayed interest in verification yet seems to have limited experience of working on this issue in a multilateral forum beyond the P5 process”.200 Dr Elbahtimy suggested the UK could help to build “regional capacities in arms control and verification” in the Middle East. Capacity building could “present a tangible contribution” to efforts to build a Middle East WMD-Free Zone (discussed below), and verification work “could contribute to a better-informed discussion about the actual challenges, solutions and opportunities in regional arms control”.201

    112.The UK’s active role in developing effective techniques and partnerships for the verification of nuclear disarmament is a helpful contribution to the disarmament agenda. The Government should continue this work, and consider opportunities for using new technologies in verification.

    113.The Government should consider engaging China in its work on nuclear disarmament verification.

    114.The Government should consider facilitating discussion and technical work on nuclear verification with Middle Eastern countries, to build regional capabilities and increase dialogue on non-proliferation and disarmament.

    The P5 process

    Box 4: The P5 process

    In 2008 Lord Browne of Ladyton, then Secretary of State for Defence, suggested establishing a process for the Nuclear Weapon States to discuss their NPT obligations. He said:

    “For the first time, I am proposing to host a conference for technical experts from all five recognised nuclear states, to develop technologies for nuclear disarmament.” This technical conference of the laboratories from the five recognised Nuclear Weapon States would meet before the 2010 RevCon, to enable the five states to demonstrate their engagement in a process of mutual confidence building and trust.202

    The chairmanship of the P5 process rotates between the members.203

    The P5 met regularly until 2018, when the process was suspended as a result of the increase in global tensions following the chemical weapons attack in Salisbury.204 Under China’s leadership the P5 process has recommenced,205 and met in Beijing in January 2019.

    115.The genesis of the P5 process is set out in Box 4. Lord Browne said the purpose had been “to bring the P5 together in a way that would generate a convincing dialogue that could convince Non-Nuclear Weapon States in the context of the NPT that the they were taking their obligations under the treaty seriously.”206 The first P5 conference, held in London in 2009, “succeeded in bringing together for the first time policy officials, military staff and nuclear scientists from all five Nuclear Weapons States”.207

    116.Paul Schulte, Honorary Professor, University of Birmingham, and Professor Nicholas J. Wheeler, Director of the Institute for Conflict, Co-operation and Security, University of Birmingham, said it created “a space for senior diplomats and security officials to cultivate a greater awareness of their counterparts’ security fears, and above all, how their own plans and actions may be contributing to these fears.”208 The Minister said that while the Nuclear Weapon States did not “see eye to eye on all issues”, the P5 process increased their “understanding of each other’s policy positions, capabilities and doctrines”. This was “important to avoid miscalculation or misunderstanding, as well as to build trust.”209

    117.Lord Browne, however, said he soon became “extremely disappointed” in the process: “I thought I was creating a dynamic for disarmament and peace, and what I created was a cartel—a group of Nuclear-Weapons States that in many other ways could not bear the sight of each other, but when it came to the common ownership of nuclear weapons were very good at articulating an argument as to why they needed nuclear weapons only because the rest of the world did not behave itself well enough.”210

    118.Dr Tzinieris said the P5 process had “not produced any meaningful progress with regard to disarmament”.211 Dr Zhao said that it functioned “as a solidarity effort” among the Nuclear Weapon States”212 and provided “protection against outside pressure for disarmament”.213

    119.Dr Tzinieris said the P5 had been “reluctant to engage with humanitarian issues in official policy statements regarding nuclear weapons”. Its response to the Ban Treaty (discussed later in this chapter) “reflected a traditional security approach and overweening reliance on deterrence theories.”214 A. Vinod Kumar, Associate Fellow, Institute for Defence Studies and Analyses, New Delhi, said that the role of the P5 in “dismissing the relevance and validity” of the Ban Treaty “cannot be overlooked and should be seen as a sign of their collective aversion to any credible disarmament process”.215

    120.Andrea Berger, then Senior Research Associate and Senior Program Manager, James Martin Center for Nonproliferation Studies, said the P5 had shifted “away from speaking primarily to an external audience towards speaking more to an internal audience”. This posed a “risk” that “the disillusion among many of the Non-Nuclear Weapon States about what the P5 process is, does and is good for will only increase”.216 Mr Plant and Cristina Varriale, Research Fellow, Proliferation and Nuclear Policy, RUSI, said Non-Nuclear Weapon States “were felt to be too broadly excluded from the process and moreover saw little concrete benefit from it”. The process was “unnecessarily opaque”.217

    121.Dr Anastasia Malygina, Associate Professor, School of International Relations, St Petersburg University, said the P5 countries had had an “agreement to avoid mutual criticism during the NPT review process”. She said that “on the initiative of the Western countries” the P5 had “stepped away from” this agreement, which had “seriously undermined co-operation in spheres where Russia and the West had no serious disagreements”. She said the US, France and the UK had “started to bring up issues not directly related to the non-proliferation of nuclear weapons” in the P5 context. Russia’s view was this “aggravates the situation within the NPT review cycle, where the atmosphere is already tense”.218

    122.Ms Berger said the P5 process was “the first time” that China had been involved in a “multilateral semi-disarmament forum”. For as long as China was “actively trying to demonstrate to those outside the P5 that it is the most disarmament-oriented and forward-leaning of the Nuclear Weapon States”, there was “something there that can be built on”.219

    123.Lord Browne said that China deserved “a significant amount of credit for what they have achieved” in restarting the process, and this was a positive step ahead of the 2020 RevCon.220 Opportunities for UK chairmanship of the P5 are discussed in Chapter 5.

    124.The P5 is an important initiative in nuclear diplomacy, which could play a positive role in co-ordinating the implementation by the five Nuclear Weapon States of their Nuclear Non-Proliferation Treaty commitments. It must not become a ‘cartel’ of Nuclear Weapon States, simply lecturing others on why their continued possession of these weapons is justified.

    P5 meetings in the run-up to the 2020 RevCon

    125.Ms Berger described China’s leadership of the P5 process as “limited”, “but the fact that it has been willing to step forward and take on some projects in the P5 context” had provided a foundation.221 Ms Price said the group was working on a glossary of nuclear terminology and a common reporting format, which was “a way of encouraging transparency on the part of other P5 members to show the rest of the NPT membership that we are engaged and we are talking to each other”.222

    126.The Baptist Union of Great Britain, the Church of Scotland, the Methodist Church in Britain and the United Reformed Church thought that “agreement on definitions and reporting standards may be necessary”, but “future success” was “likely to be measured in terms of the quality of discussion around nuclear doctrines, arms control and disarmament”.223

    127.Ms Nakamitsu said the group had “had a substantive engagement” on “how to move forward with the Article 6 obligations”. They had “also started to discuss nuclear doctrines, their security doctrines, and some of the measures that they could pursue potentially on transparency”.224 Mr Franklin said that “as part of the P5” they had met “in the margins of the UN First Committee”, and “ had a fairly detailed presentation from the nations on our nuclear doctrine and policy”.225 Ms Nakamitsu said that “interesting conversations and discussions” were “still taking place among the P5”, and this would be “one of the most important elements when it comes to the grand bargain put on non-proliferation and disarmament going together”.226

    128.The P5 met in Beijing in January 2019. The Minister said the meeting had included commitments—set out in the Chairman’s note—to sharing responsibility for international peace and security, jointly safeguarding the NPT and continuing to use the P5 platform for dialogue. A “public session with academic representatives” had been held on the second day of the conference.227

    129.Dr Malygina said that the fact that no joint statement was agreed in January showed that “trust is really very low.”228 Dr Zhao said the nuclear glossary had been an “important deliverable” of the meeting, but it demonstrated the limited capability of the P5 format to generate progress. There had been “little agreement on nuclear reduction or greater transparency; even on less controversial/sensitive issues, such as the joint development of nuclear disarmament verification methodology and technology”.229

    130.We welcome the role played by China as the chair of the P5 process in 2018–19. Trust between the P5 remains low, and meetings in the P5 format could help to build understanding and trust between these states. This could, in the run up to the 2020 Review Conference, contribute to a reduction in the risk of nuclear use.

    Assessing the NPT regime

    131.Dr Grossi said the NPT had “lived through ups and downs in the cycle of history, with the end of the Cold War and … the emergence of new challenges. The treaty arches over all these events.”230

    132.Dr Elbahtimy said that “From the early to mid-1990s” the NPT had become “an almost universal regime, a set of rules that were to be applied to everyone”.231 The FCO told us that “The majority of states recognise their obligation to support and reinforce the existing counter-proliferation and disarmament framework.”232

    133.While the FCO considered it to be “a success in all three of its pillars”,233 Rear Admiral Gower assessed that only “two of the three pillars”—non-proliferation and peaceful uses—had been “very successful”; there was “dissatisfaction with the disarmament pillar and the perceived lack of progress”.234 We consider each pillar in turn.


    134.Our witnesses praised the record of the NPT in containing the threat of horizontal proliferation.235 Ms Nakamitsu said the NPT was “one of the most successful treaties … there was a prediction that there would be 30 or 40 nuclear-armed states, it has prevented that.”236 Mr Koenders said there could have been “much more” proliferation, citing the examples of Libya, Kazakhstan and South Africa.237 Ms Price said that it had “prevented countries from acquiring nuclear weapons … we have the five recognised weapon states and roughly four others, so that is a success.”238

    135.Dr Elbahtimy said that that international regimes were “more than just the words in the treaties themselves; they have some moral authority”.239 The NPT has created a norm against proliferation: Mr Plant said that were a state to withdraw from the NPT “there would be a succession of major partners beating down their door to make plain the consequences”.240 Lord Browne said that the acquisition of nuclear weapons had become a route to “pariah” status. It was “the only time in my lifetime when no country is manifestly seeking to develop a nuclear-weapons system” which was “an amazing achievement, and a significant part is down to this treaty”.241

    136.Dr Grossi said that “countries that violate or find themselves in a position marginal to the NPT would have enormous trouble internationally”. The consequences would be referral to the UN Security Council, and “enormous costs of entry for whatever they may like to do in the peaceful uses area—getting technology and co-operation—let alone the cases where they proliferate or intend to proliferate”. He said that “for countries in good standing in the international community”, being a State Party to the NPT was “an indispensable rule of civility in international life”.242

    137.However, while the NPT has been successful in containing proliferation, it has not prevented it entirely. Since the NPT was signed in 1968, four states have developed nuclear weapons: North Korea, India, Pakistan and Israel.

    138.Dr Grossi said that because of the way the NPT is articulated, and because it “operates in conjunction with the safeguards system administered by the IAEA”, it was “very difficult” for the development of nuclear weapons by a Non-Nuclear Weapon State to go unnoticed. North Korea “had to leave the NPT” because of this work.243

    139.Mr Kumar, however, said that North Korea was the most “destabilising” to the NPT regime of the four, because it had been a State Party and abused its provisions before unilaterally leaving the treaty.244 Ms Berger said it had taken “a systematic sledgehammer to all the norms that the NPT community has been trying to create about not testing, responsible nuclear conduct and, indeed, proliferation”.245

    140.Mr Kumar said that, although less of a challenge to the NPT regime than North Korea, India, Pakistan and Israel “continue to be the key inspiration for the deviant behaviour intermittently seen among many NPT state-parties”. Iran, for example, had “cited the Indian case throughout the negotiations that were undertaken to address its nuclear deviance”.246

    141.Dr Clegg said that India, Pakistan and Israel’s ability to develop nuclear weapons “without much censure”, while Iran and North Korea had been subjected to sanctions, demonstrated “double standards” by the international community, which undermined the NPT.247 (Iran is discussed in Chapter 4.)

    142.Dr Paul said the NPT was “interpreted by India as a western ploy or ‘trojan horse’ designed to disrupt economic prosperity and the right to self-determination”. India regarded itself to be “exceptional” and had sought a “back door to the privileges previously reserved exclusively to NPT” (such as access to civilian technology, discussed below).248

    143.Dr Paul said there was a “paradox” to Pakistan’s reluctance to sign the NPT. “On the one hand, policy-framers accept the non proliferation norm” and were “keen to impress their intention to pursue disarmament talks with India”, but on the other, “nuclear proliferation in the form of Chinese technical assistance is also viewed as essential for meeting Pakistan’s security needs”.249

    144.Dr Avner Cohen, Professor of Nonproliferation Studies, Middlebury Institute of International Studies at Monterey, said that Israel’s ‘nuclear opacity’ (see Chapter 2), had given it a “special ‘exemption’ as far as its nuclear conduct and policy”. It was “the only nuclear power whose conduct and policies are officially ‘off discourse’, both domestically and by friendly foreign governments”. He said that “all major Western countries, the UK included, align themselves behind the American policy on Israel’s nuclear capability. They all quietly accept Israel’s nuclear ‘exemption’ while publicly claiming ignorance.” 250

    145.He said that Israel had refused to join the NPT, and paid “almost no price—political, diplomatic or even moral—for nuclear possession”.251 This was “a constant sore for both the credibility and integrity of the global non-proliferation regime as well as for the non-proliferation stance of those Western states that support the nuclear exemption”.252

    146.Ms Nakamitsu said that universal membership of the NPT was “probably not in sight”.253 The UK continues “to work with all three countries to bring them more into the international non-proliferation regime and to encourage them to sign the NPT as Non-Nuclear Weapon States”.254

    147.Mr Kumar noted that, while not signatories, both India and Pakistan have declared adherence to the principles of the NPT.255 Although NPT membership was not likely, Shatabhisha Shetty, Deputy Director, European Leadership Network, thought it important to “continue to try” to engage them.256 Ms Nakamitsu advocated keeping these states “engaged in disarmament and security platforms, including the UN and other multilateral platforms.”257 Dr Meier said they had participated in the nuclear security summits during the Obama Administration, which had been useful.258

    148.Trident Ploughshares said that while India, Pakistan and Israel joining the NPT would be “helpful”, “the main issue … undermining the NPT” was “the failure of the nuclear-armed states” to meet their disarmament obligations259 (discussed below).

    Peaceful uses

    149.Rear Admiral Gower said the peaceful uses pillar had “largely been successful, because it tied in with the non-proliferation pillar”.260 It had “allowed a large number of Non-Nuclear Weapons States to acquire full nuclear technology”.261

    150.Dr Grossi said this quid pro quo was important because nuclear energy continued to be “an important factor in the energy matrix of many countries, particularly the big emerging economies”.262 For example, Argentina’s civil nuclear programme had “thrived after joining all the nuclear regulations and nuclear norms”. It was also “one of the few exporters of nuclear technology in the southern hemisphere, precisely because [Argentina] joined the NPT and the export control regimes”. The message he took to developing countries, was that “everything they do in their small research reactor or their nuclear medicine facility, be it in north or southern Africa, central America or south-east Asia, is possible because there is an NPT that allows for it”.263

    The Nuclear Suppliers Group

    151.The FCO said that the NSG, in regulating transfers of nuclear materials for peaceful uses (outlined in Box 3), was “a fundamental component of nuclear non-proliferation”.264 Dr Grossi said countries not party to the NPT faced a “high cost of entry” for nuclear materials for civilian use, because those outside the NPT could not be members.265

    152.Witnesses raised two issues relating to the NSG. First, the Executive Committee of British Pugwash said that the NSG had “been a source of tension within the NPT community” for many years. Article 4 of the NPT “contains an undertaking to facilitate transfers” of nuclear technologies to signatories. However, the NSG had a “bias towards” the denial of the transfer of dual-use nuclear technology. The Non-Aligned Movement (NAM),266 and some non-NAM members, viewed this as “inconsistent with Article 4” of the NPT. It said that these countries argued that States Parties had the “sovereign right to make use of all nuclear technologies as long as the use is peaceful, and the right is exercised in conformity with the NPT’s non-proliferation provisions”. This tension was “unlikely to pose an existential threat to the NPT” but presented “an ongoing challenge for nuclear diplomacy.”267

    153.Second, witnesses said that the treatment of India by the Nuclear Suppliers Group had tested the NPT regime. India has sought membership but China has blocked its admission, because it has not signed the NPT.268 However, in 2008, under the US–India Civilian Nuclear Co-operation Agreement, India was “allowed to buy and sell nuclear fuel and technology with the rest of the world for civilian purposes, without having to join the Nuclear Non-Proliferation Treaty … or dismantle any of its existing nuclear weapons or its nuclear weapons-making programme”. Under the terms of the deal, India agreed to separate its civilian nuclear facilities from those that were part of its strategic programme, and open up its civilian facilities to inspections by the IAEA.269

    154.Dr Meier said this exemption was “an example of how not to do it. We have watered down safeguard standards and nuclear export control standards without India committing to significant steps towards nuclear disarmament and arms control to constrain its nuclear capabilities”. This damaged both the NSG and the NPT.270 Mr Kmentt said that “if a country such as India … that has stayed outside the NPT could nevertheless gain access to the benefits with respect to nuclear co-operation, one would lose one of the key points of keeping countries in the NPT.”271

    155.Dr Adil Sultan Muhammad, Visiting Research Fellow, War Studies Department, King’s College London, said that granting “country-specific exemptions to [a] non-NPT state like India” was “likely to create further dissent amongst the NPT as well as other non-NPT states”.272 Dr Paul said Pakistan was seeking similar exemptions to the NSG rules as had been granted to India. He thought this “could restore the political imbalance and signal genuine inclusivity, whilst also strengthening some technical dimensions of the global non proliferation and export control regimes.”273


    156.Ms Nakamitsu said that, compared to the peak of the Cold War, nuclear disarmament had “progressed enormously … Some 88% of nuclear arsenals have been reduced”.274

    157.Ms Price said the NPT had given the Nuclear Weapon States “the confidence” to disarm. Around “three-quarters of the nuclear warheads that existed” had been disposed of.275 Ms Cox said “the number of nuclear weapons deployed on European soil” had been reduced “significantly—by about 85%—since the end of the Cold War.”276 The five Nuclear Weapon States had endorsed, and continued to promote, the ‘step-by-step’ approach to achieve disarmament, which “envisages measures taken in tandem with an improving security environment”.277 Ms Price said a “very long-term view” was needed—the focus should be on “the reductions that have happened”.278

    159.However, Ms Nakamitsu said that while the world had once been “moving towards a substantive Article 6 implementation”, “that movement has stalled”. “The number of nuclear arsenals today is some 14,000, and 90% of those are still owned by the two nuclear superpowers.”279 Dr Roberts acknowledged that the “step-by-step process embodied in the NPT implementation process” had “lost credibility”. NPT diplomacy had “come face-to-face with ambitions and commitments that proved unrealistic in the circumstance”.280

    160.Dr Grossi said the disarmament provisions of the NPT were “under great stress”.281 The “big question” facing “all the 191 members of the treaty” was “whether the fact that we have not reached the final goal of a world without nuclear weapons would put the NPT into question “.282

    161.BASIC said that lack of progress on disarmament was a result of “the current security and diplomatic environment”283 (discussed in Chapter 2). Mr Miller said the US, the UK and France had “reduced their nuclear arsenals dramatically since the end of the Cold War”, but “Russia has maintained a bloated nuclear force and China is busily expanding its own”. He dismissed the suggestion that the NPT was “in peril because the Nuclear Weapons States have not eliminated all of their nuclear weapons” as “wrongheaded”.284

    162.Ms Cox said it was “clear that the current conditions are not right for further reductions”, but “we try to do what we can to create the right conditions, we have to balance that with the security environment in which we live.”285 Rear Admiral Gower cautioned that advocates of disarmament did not “take into account the reductions that have taken place”. However, he agreed “that it is right to perceive today that the disarmament pillar goals are further away and less visible than they were in 2009–10”.286

    163.Dr Tzinieris noted that many countries argued that the NPT required a “re-balancing of the relative value assigned to the three pillars” to give more weight to disarmament.287 Dr Ritchie said many countries were “concerned that the nuclear-armed states will never deliver on their commitments to disarm and that they view their possession of nuclear weapons as permanent”.288 Ms Fihn concluded that “disarmament does not happen in that treaty.”289

    164.Dr Tzinieris said this was in part due to how the NPT was drafted. First, “Article 6, which concerns disarmament, is lacking in legal strength and its meaning is open to interpretation.”290 Dr Grossi said it contained “no chronology or specifically set timelines”.291 Second, the “implicit hierarchy” between those with and without nuclear weapons was “encapsulated within the NPT”, which rendered it “incapable of unconditionally delegitimising nuclear weapons”.292

    165.Scientists for Global Responsibility said the failure of Nuclear Weapon States to fulfil their disarmament commitments under the NPT “provides greater justification for [nuclear possessor states] outside the treaty to follow suit.”293

    166.We consider below two particular challenges relating to disarmament under the NPT—nuclear modernisation programmes and issues surrounding the Middle East WMD Free Zone.

    167.The Nuclear Non-Proliferation Treaty remains a critical part of international security. The success of the treaty will remain of central importance to the UK’s security and to the rules-based international order as a whole.

    168.The Nuclear Non-Proliferation Treaty’s successes—near-universal membership, a considerable reduction in nuclear stockpiles since the 1980s, and the establishment of an international norm against new states acquiring nuclear weapons—should be lauded.

    169.The presence of nuclear-armed states outside the Nuclear Non-Proliferation Treaty remains a challenge. The UK should pursue opportunities to include nuclear non-proliferation and disarmament in its bilateral discussions with India, Pakistan and Israel.

    170.Although nuclear possessor states outside the Nuclear Non-Proliferation Treaty are unlikely to disarm in the short term, the UK should continue to advocate for the universalisation of the treaty.

    171.Largely as a result of the worsening security environment, global progress towards disarmament has stalled. We urge the Government to set out its view on what the necessary global conditions for disarmament would be, and use its position in the P5 to encourage progress under this pillar of the NPT.

    Nuclear modernisation programmes

    172.Ms Nakamitsu said “all nuclear-weapon states are engaged in what they call modernisation.”294 The potential implications of modernisation for nuclear risk are explored in Chapter 2.

    173.The FCO said that “Maintaining and renewing elements of a State’s nuclear deterrent capability to ensure its continued safety and reliability, including through replacement and updating of obsolete elements of the system as they reach the end of their operational life” was “a necessary aspect of being a responsible nuclear weapon state.” This was “fully consistent with obligations under the Article 6 of the Nuclear Non-Proliferation Treaty.”295

    174.However, Ms Nakamitsu said that “qualitatively, Nuclear-Weapon States might be in fact increasing their nuclear capability”.296 Dr Zhao said modernisation could lead to enhanced capabilities—such as the greater accuracy of missiles, and more advanced missile retargeting capability.297 Dr Meier described this as “vertical proliferation within the Nuclear Weapon States”,298 a point also made by Mr Plant and BASIC.299

    175.Dr Tzinieris said that safety and risk reduction were “rarely the principal motivation for modernisation programmes”. Both Non-Nuclear Weapon States and civil society groups were “becoming increasingly wary of attempts to frame modernisation programmes in disingenuous ways”.300 The Executive Committee of British Pugwash said that “the signal that modernisation and renewal … sends to NPT Non-Nuclear Weapon States” was “deplorable”.301

    176.Scientists for Global Responsibility said that “Any and all renewal or nuclear ‘modernisation’ programmes fundamentally undermine nuclear disarmament and non-proliferation regimes”.302 From the perspective of Non-Nuclear Weapon States, Mr Kmentt said that none of the Nuclear Weapon States had taken “significant steps to move away from their reliance on nuclear weapons”.303

    177.Dr Zhao and Diana Ballestas de Dietrich, former Policy and Strategy Officer, Office of the Executive Secretary of the Preparatory Commission of the Comprehensive Nuclear-Test-Ban Treaty Organisation, said both renewal programmes and technological developments underscored and perpetuated reliance on nuclear weapons”.304

    178.We consider the modernisation programmes of the nuclear possessor states in turn.


    179.Mr Heisbourg said Russia was attempting “to make up for its post-Soviet weaknesses” through “‘technological creativity’, including great ambiguity about the precise nature of its new weapons systems”. It was “erasing and blurring the distinction between conventional and nuclear”.305

    180.For example, Mr Miller said Russia had four new SSBNs—ship, submersible nuclear ballistic missiles—and “Mr Putin also routinely boasts about new exotic nuclear systems Russia is building”.306 These included the ‘Kanyon’ torpedo—a prototype autonomous underwater nuclear-powered and nuclear-armed weapon, which can deliver both conventional and nuclear payloads307—and a nuclear powered cruise missile.308 It successfully tested the Avangard—a hypersonic nuclear-capable weapon designed to manoeuvre in the upper atmosphere309—in December 2018.310

    The US

    181.Mr Plant said the aspects of the US’s nuclear programme that had already been funded were “modernisation”, but the US was “more open to accusations” about the plans set out in the 2018 Nuclear Posture Review.311 Dr Clegg said this had “reversed the previous policy of promoting nuclear arms control”—it placed “new emphasis on the role of nuclear weapons in US national security strategy, promoting the development of new nuclear capabilities, including low-yield tactical nuclear weapons”.312

    182.Mr Miller took a different view: the US had not deployed a new nuclear system “in this century” and would “not begin to field new systems until the mid-to-late 2020s”. He said that without modernisation the existing US system would “have to be retired without replacement”.313

    183.PAX said that some countries which participate in nuclear sharing with the US were also engaged in modernisation. Germany, Italy, Belgium and the Netherlands have signed contracts for “the modernisation of bunkers designed to continue hosting the US B61 gravity bombs”.314


    184.Dr Leveringhaus said China’s modernisation programme had been “underway since the 1990s” and was “ now starting to bear fruit under Xi Jinping”.315 Dr Clegg said China had been “investing in and modernising its ground based cruise and ballistic missiles systems which would have the capability to strike US bases, for example in Okinawa and Guam, and possibly destroy a US aircraft carrier in a single strike”.316

    185.Mr Miller said China was not just modernising but expanding its nuclear capabilities. It had been “deploying for years tens each of two new types of ICBMs, has four new SSBNs with another building, is seeking to build a new long-range bomber, and has the most formidable ballistic missile programme in the world”.317 Dr Roberts said it had “not embraced nuclear transparency while it modernises and expands”.318

    The UK

    186.Ms Price said that “as a responsible nuclear-weapons state, as long as we possess weapons we need to maintain them to make sure that they are in good condition and that we have the right arsenal for our legitimate deterrent and self-protection defence. We also need to ensure that anything obsolete is renewed.”319

    187.Mr Plant said it was “fair to say that the UK’s is more accurately described as nuclear modernisation than, say, Russia’s progress”.320 Rear Admiral Gower said the UK was “probably two-thirds of the way through a cyclical expenditure, having decided to replace the delivery platform—the submarines—having essentially agreed before that to co-fund the missile extensions with the US.” The “third leg of the modernisation” would be “sustaining a warhead to the end of the life of the submarine and the missile.”321

    188.Ms Fihn, however, was “disappointed in the UK’s modernisation programmes of its nuclear weapons”.322 Dr Ritchie said “the fact that we are recapitalising our Trident SSBN programme and recommitting to nuclear deterrence for another generation, talking of being a nuclear armed state into the 2070s and 2080s and revalidating the importance and centrality of nuclear weapons for our security, cannot but undermine anything that we may do to show that we are taking short-term to long-term nuclear disarmament seriously.”323


    189.Rear Admiral Gower said France’s modernisation timetable was largely aligned with that of the UK.324 France’s airborne and submarine weapons are due to be updated in around 2035.325 PAX said that parts of the French modernisation programme—the design and development of the ASMPA (strategic and ultimate deterrent air-launched nuclear missile) to extend its life beyond 2035 and its successor, ASN4G, which will become operational in 2035—were examples of contracts which undermined the non-proliferation and disarmament regime, “by engaging companies for work related to nuclear weapon production and maintenance for decades”.326

    190.France plans to undertake concept studies for a new nuclear warhead, as the current systems will become obsolete in the 2030s.327 Its nuclear deterrent will receive €37 billion (£31.9 billion) by 2025.328

    Nuclear possessor states outside the NPT


    191.Mr Kumar said that India was increasing its arsenal in a way that contributed to the “global trend of nuclear re-armament”.329 Mr Plant said that, compared to China, India’s capabilities were “significantly further behind”.330 It had “recently declared its accomplishment of a nuclear triad”—land, sea and air capabilities—”through the operationalisation of its nuclear-armed and-powered nuclear submarine force”.331

    192.Dr Paul said India’s pursuit of these capabilities were not necessarily inconsistent with its doctrine of ‘credible minimum deterrence’, but “the pursuit of ballistic missile defence shifts the nuclear trajectory towards implementing full spectrum offence / defence dominance”. It was also developing “nuclear tipped short-range ballistic missiles and pursuing Multiple Independently Targetable Reentry Vehicles”. He thought that “instead of reducing nuclear force levels” India was developing “a full matrix of strategic and defensive capabilities” which undermined the drive towards nuclear disarmament. Pakistan and China were “likely to follow suit”.332


    193.Mr Kumar said Pakistan was also contributing to the trend of global rearmament. It had “advanced from an initial capability of existential deterrence to full-spectrum deterrence”.333 Dr Paul said it had “recently carried out the flight test of the Babur-3, its new submarine-launched cruise missile”. This enabled it “to develop a sea-based nuclear deterrent in response to India’s emerging SSBN capability”. It was also “a dual-capable system and thus highly destabilising”.334


    194.As a result of its policy of nuclear opacity, details of Israel’s modernisation programme are not known.

    North Korea

    195.The North Korean nuclear programme is considered in Chapter 4.

    196.Nuclear modernisation is a necessary part of the maintenance of nuclear weapons and can make these weapons more secure. However, the programmes of many nuclear possessor states go well beyond what can properly be described as modernisation, introducing new capabilities and potentially increasing nuclear risk. We are particularly concerned about new developments in the field of tactical nuclear weapons.

    197.The UK’s nuclear modernisation programme, although not without its critics, focuses on the renewal of its existing capabilities for a minimum credible deterrent. The Government should encourage other nuclear-armed states to exercise restraint in their modernisation programmes and to avoid expanding their nuclear capabilities.

    A Middle East Weapons of Mass Destruction-Free Zone

    Five nuclear weapon-free zones have been recognised by the UN:

    Mongolia is also an UN-recognised nuclear-free zone. Nuclear weapon-free areas have also been established in the Antarctic, the sea-bed and outer space.336

    198.Figure 4 shows the existing nuclear weapon-free zones.

    The history of a Middle East Weapons of Mass Destruction-Free Zone

    199.The only nuclear possessor state in the Middle East is Israel, which has not acknowledged its nuclear arsenal and is not a signatory to the NPT. All other countries in the region are States Parties to the NPT.

    200.The development of a Middle East Weapons of Mass Destruction-Free Zone—covering all weapons of mass destruction and their means of delivery—was first formally proposed in a resolution submitted to the UN General Assembly by Iran and Egypt in 1974.337 Further General Assembly resolutions supporting the establishment of a Middle East WMD-Free Zone were adopted by consensus.338

    201.At the 1995 NPT RevCon the Arab States Parties to the NPT, led by Egypt proposed a resolution on the issue.339 The proposed indefinite extension of the NPT that year340 gave these states maximum leverage, and there was “relentless campaigning by Arab states”.341 In return for their support for the indefinite extension of the NPT, the Final Document of the RevCon stated:

    “The development of nuclear-weapon-free zones, especially in regions of tension, such as in the Middle East, as well as the establishment of zones free of all weapons of mass destruction, should be encouraged as a matter of priority, taking into account the specific characteristics of each region. The establishment of additional nuclear-weapon-free zones by the time of the Review Conference in the year 2000 would be welcome.”342

    202.A resolution on the Middle East was adopted, which stated that the Conference of the Parties to the Treaty on the Non-Proliferation of Nuclear Weapons: “Endorses the aims and objectives of the Middle East peace process and recognizes that efforts in this regard, as well as other efforts, contribute to, inter alia, a Middle East zone free of nuclear weapons as well as other weapons of mass destruction”.343

    203.Dr Elbahtimy said this agreement was “one of the key reasons why it was possible to indefinitely extend the NPT in 1995”.344 Since 1995 the issue had played “an important, and sometimes overbearing, role during the NPT review process”.345

    204.At the 2010 RevCon there was “an idea of convening a conference in 2012, to be attended by all states in the Middle East”.346 Dr Grossi said that the UN’s facilitator had “conducted a very thorough process of consultations around the region, but unfortunately no positive outcome came out of that”.347 In 2015, this was a significant factor in the failure to agree a Consensus Final Document at the NPT RevCon.348

    The reasons for failure to agree a WMD-Free Zone

    205.BASIC said that “many Israelis believe their security depends upon a nuclear ‘Samson option’ of massive retaliation against their neighbours”, which they were “not yet prepared to give up.”349 The US’s “positions … protect Israel’s resistance to being put on the spot about the Middle East zone”.350

    206.Egypt and the other Arab states saw “a deep injustice in current arrangements” and were “suspicious of never-ending negotiations”, while “Iranians carry suspicion of external powers and are caught in proxy conflicts with their Gulf neighbours”.351 Dr Elbahtimy said that both the Arab states and Iran felt there were “double standards” in “the way Israel’s nuclear programme is handled”.352

    207.BASIC said the failure to progress had “poisoned the well”.353 Mr Kmentt said this—alongside dissatisfaction with the pace of disarmament—had led “to a crisis of confidence and trust in the NPT.” The advantage to Middle Eastern states of maintaining the NPT had “been there until now”, but it was “becoming fractious”. If the NPT collapsed, “a nuclear arms race in the region” would be likely. There were “already several countries”, including Turkey and Saudi Arabia, where nuclear weapons were “being more or less openly discussed”. Were that “trend to materialise then the impact on security, both regional and international, would be very negative.” The NPT consensus “still holds” because of this risk; it was the reason for “the support of the Middle Eastern countries for the tough line against the Iranian nuclear programme”.354

    208.Ms Ballestas de Dietrich said that as biological and chemical weapons have “already been banned”,355 and Israel is the only nuclear possessor state in the region, “the issue at stake is not about a WMD free zone, but ultimately about disarming Israel.”356 There were “no prospects in the foreseeable future for Israel to give up the nuclear weapons it does not even admit to have.” “Credible efforts” would therefore need “to address the threats that have led Israel to develop nuclear weapons in the first place” and “bring Egypt, Iran and Israel to the table (any table) to begin discussions on their respective security concerns.”357

    209.Alexandra Bell, Senior Policy Director, Center for Arms Control and Non-Proliferation, and BASIC thought there were confidence-building steps that could be explored. Ms Bell suggested a testing moratorium in the region, which “should not be too hard, because none of [the states] has plans to test nuclear weapons”, then getting Israel, Iran and Egypt to ratify the Comprehensive Nuclear-Test-Ban Treaty (discussed in Chapter 4). These measures could “salvage the consensus points that already exist”.358 Ms Nakamitsu suggested building “a number of informal dialogue mechanisms” around the formal UN mandated conference, to “encourage all states in the region to be engaged in such a process.”359

    Towards a conference in 2019?

    210.Dr Elbahtimy said that in 2018 the Arab states had sponsored a UN General Assembly resolution that “asked the UN to convene a weeklong WMDFZ Conference in 2019”. This had been supported by 103 countries, with 71 abstentions and three votes against, from the US, Israel, and Micronesia.360 Ms Nakamitsu said the UN Secretary-General was working on the conference, and there had been “quite a lot of substantive discussion”. She thought it would probably be “a very difficult process”.361

    211.Dr Grossi said the conference would be held in New York “probably in November or by the end of” 2019. He did not know what the outcome would be, but welcomed this “new, added path to this goal to which we all subscribed”.362

    212.He said questions remained over whether the US, Israel, the UK and other P5 states would participate.363 Ms Bell said some countries were “saying they should go ahead and have a conference … without the consent and buy-in of Israel”. The US thought this “a terrible idea—this is a regional problem, so all members of the region should be brought in”.364 Ms Price said that “at the moment” Israel had not agreed to attend, which the UK thought was “a fatal flaw”.365

    213.The FCO said the UK remained “fully committed to the 1995 Resolution”. It was “prepared to actively support and facilitate renewed regional dialogue aimed at bridging the differing views in the region on arrangements for a conference that is freely arrived at by all states in the region as set out in the NPT 2010 Action Plan.”366 Mr Baklitskiy said that the UK, as a co-sponsor of the 1995 resolution, “should try to engage the Arab states as well as Iran and Israel in the talks”.367

    214.The issue of a Weapons of Mass Destruction-Free Zone in the Middle East has become one of the most contentious for successive Non-Proliferation Treaty Review Conferences. The UK should continue to support work towards the forthcoming UN conference on a Middle East Weapons of Mass Destruction-Free Zone, and should encourage Israel to participate.

    215.The Government should also support dialogue and confidence-building steps in the Middle East—such as a regional testing moratorium—with the aim of increasing trust and improving the security environment. We believe that any increase in dialogue and reduction in tensions in the Middle East would be welcome and could make a contribution to the overall success of the 2020 Nuclear Non-Proliferation Treaty Review Conference.

    Dissatisfaction of Non-Nuclear Weapon States

    216.Witnesses said that, as a result of the Nuclear Weapons States not having fulfilled their disarmament obligations, significant dissatisfaction had arisen among Non-Nuclear Weapons States.368 When they had agreed to an indefinite extension of the NPT, Non-Nuclear Weapons States had not accepted indefinite possession of nuclear arsenals, or perpetual modernisation.369

    217.Many witnesses pointed to the inherent lack of balance between the five Nuclear Weapon States and the Non-Nuclear Weapon States as a problem.370 This created “a sense of futility on the part of the Non-Nuclear Weapon States over reaching any meaningful progress”, which led to “more confrontational and obstructive behaviours”—such as blocking Final Documents at RevCons.371 The Humanitarian Impacts initiative grew out of this frustration.

    The Humanitarian Impacts initiative

    218.Dr Rebecca Johnson, Executive Director, Acronym Institute for Disarmament Diplomacy, said that from 2005 “civil society had been encouraging scientists to update studies on the risks, impacts and consequences of nuclear weapons use, deployments and proliferation.372

    219.Dr Tzinieris said that the resulting Humanitarian Impacts initiative “was a turning point for global nuclear diplomacy”. Evidence had been “employed to show the long-standing impacts on the environment, climate and food security”. This was “a new way of framing the debates, which had historically been dominated by ‘techno-strategic’ discourses focused on deterrence theories”.373 An article in the Bulletin of the Atomic Scientists on these data noted that while “improvements in climate modelling have provided greater insights into the long-term consequences of nuclear weapons use”, the studies contained “significant assumptions and uncertainties”.374

    220.Dr Johnson said that at the 2010 RevCon for the first time there was discussion of the issues of “international humanitarian law, the use of nuclear weapons and … the need to negotiate further disarmament instruments” in the Final Document.375 Following this, international conferences on the ‘humanitarian impacts of nuclear weapons’ were hosted by Norway, Mexico and Austria in 2013 and 2014.376 Ms Nakamitsu said there had been “very strong motivation on the part of Non-Nuclear Weapon States to call for an understanding of the catastrophic humanitarian consequences of nuclear weapons”.377

    221.All countries were invited to participate in these conferences.378 The UK attended the final conference, in Vienna in December 2014.379

    222.The conferences were the precursor to the drafting of a resolution, adopted by the UN General Assembly on 23 December 2016, committing “to negotiate a legally binding instrument to prohibit nuclear weapons, leading towards their total elimination”.380

    The Treaty on the Prohibition of Nuclear Weapons (the Ban Treaty)

    Box 5: The Treaty on the Prohibition of Nuclear Weapons (the Ban Treaty)

    The Treaty on the Prohibition of Nuclear Weapons (TPNW) includes a comprehensive set of prohibitions on participating in any nuclear weapon activities. These include undertakings not to:

    • develop;
    • test;
    • produce;
    • acquire;
    • possess;
    • stockpile;
    • use; or
    • threaten to use nuclear weapons.

    The treaty prohibits the deployment of nuclear weapons on national territory, and the provision of assistance to any state in the conduct of prohibited activities.

    States Parties will be obliged to prevent and suppress any activity prohibited under the treaty undertaken by persons or on territory under its jurisdiction or control.

    It also obliges States Parties to provide adequate assistance to individuals affected by the use or testing of nuclear weapons, as well as to take necessary and appropriate measure of environmental remediation in areas under its jurisdiction or control contaminated as a result of activities related to the testing or use of nuclear weapons.

    It was adopted by a vote of 122 states in favour (with one vote against and one abstention) in July 2017.381 It was opened for signature in September 2017. It will enter into force 90 days after the fiftieth instrument of ratification, acceptance, approval or accession has been deposited.

    Source: UN Office for Disarmament Affairs, ‘Treaty on the Prohibition of Nuclear Weapons—Treaty overview’: https://www.un.org/disarmament/wmd/nuclear/tpnw/ [accessed 3 April 2019]

    223.The Ban Treaty opened for signature in September 2017 but is not yet in force.

    224.Mr Kmentt said the Ban Treaty’s “comprehensive prohibition” on nuclear weapons was “something that the NPT does not offer”. The “aspiration” was that this “should become universal at some stage”.382 Ms Fihn said this was “the main difference” between the Ban Treaty and the NPT. The former “rejects the legitimacy of these weapons, whereas the NPT, while trying to achieve disarmament, still acknowledges that these weapons are important for security.”383 The Ban Treaty was “incompatible with theories of nuclear deterrence”.384

    225.Alternative views on the role of deterrence and the right conditions for disarmament are discussed earlier in this chapter, in the assessment of the NPT’s disarmament pillar. Commenting specifically on the Ban Treaty, Mr Miller said the Ban Treaty was based on a misapprehension. It “conceives of nuclear weapons as the over-riding problem to resolve rather than recognising that preventing war among the Great Powers is the paramount security problem of our era.”385 Dr Roberts said that “some NGOs continue to advocate … disarmament steps in ways that appear not to account for the renewal of major power rivalry and the emergence of new nuclear dangers, primarily in Asia”.386 The criticism that the Ban Treaty does not take account of the security conditions facing nuclear possessor states was also made by the FCO and Ms Cox.387

    226.Ms Nakamitsu said the Ban Treaty was “a demonstration of the frustration on the part of Non-Nuclear Weapon States … that the previous commitments on nuclear disarmament and the implementation of Article 6 of the NPT have stalled”.388

    227.The Nuclear Weapon States have made clear their opposition to the Ban Treaty; collective statements by the P5 are discussed later in this chapter. NATO issued a statement in September 2017 that “Allies committed to advancing security through deterrence, defence, disarmament, non-proliferation and arms control, we, the Allied nations, cannot support this treaty. Therefore, there will be no change in the legal obligations on our countries with respect to nuclear weapons.”389

    The negotiation of the Ban Treaty

    228.Dr Johnson said that the negotiations had been informed by a “multilateral humanitarian-based legal process” including the international conferences on the humanitarian impacts (discussed above) and two UN “open-ended working groups” established by the UN General Assembly. There had been “open discussions” at the UN General Assembly, with participation by “up to 140 states”.390

    229.Mr Koenders however thought the negotiation of the Ban Treaty had been “sloppy”. They had been conducted at an unnecessary speed, with the result that “A lot of the legal terms are simply not well defined”, which was a problem because it was important to be “very precise” when discussing issues such as “verification, nuclear umbrellas, responsibilities, testing”.391

    Assessment of the Ban Treaty

    Impact on the NPT regime

    230.Mr Kmentt said that the NPT’s “obligation under Article 6” was “a collective responsibility for the entire membership and not just for the Nuclear Weapon States.”392 The negotiation of the Ban Treaty was “the only way to demonstrate that we are deeply unsatisfied with the status quo and deeply concerned about how the arms control regime and the nuclear disarmament dimension in particular are moving.”393 “Most of all”, the treaty was “a manifestation of the role and responsibility of the Non-Nuclear Weapon States to discharge their obligation”.394

    231.Some witnesses suggested that the Ban Treaty undermined the NPT. Dr Sultan said it was “likely” to do so, because it brought “duplicate obligations upon the signatory states” and complicated the global non-proliferation regime.395 The FCO said it risked “undermining international non-proliferation work and the NPT”,396 a reason given by Ms Cox for why none of the NATO Allies had signed or ratified the treaty.397

    232.Mr Plant said that the “crack in the wall … if it comes; I do not think it is guaranteed to” would occur if a state decided “that it would prefer to discharge its non-proliferation obligations under the Treaty of Prohibition of Nuclear Weapons than it would under the Non-Proliferation Treaty.”398 Dr Roberts was concerned that the Ban Treaty’s standards would “give some states the political cover for abandoning their NPT obligations”.399 The Ban Treaty’s safeguards and verification measures are discussed below.

    233.Dr Tzinieris said the P5 had at different times asserted that it would “‘undermine’, ‘weaken’ and ‘damage’ the NPT”.400 Ms Price described the Ban Treaty as “a rival”,401 which Mr Schulte and Professor Wheeler said could reduce the NPT’s “universality and moral authority”.”402 Ms Price said that it had “a clause in it to say that it is the primary instrument for achieving disarmament in the world. We disagree with that; we think it is the NPT. If you introduce a competition or hierarchy of treaties, you have to believe that one is higher than the other; you have to make a choice.”403

    234.Mr Kmentt said “the assertion that the Treaty on the Prohibition of Nuclear Weapons in any way damages or undermines the NPT is just plain false”. It was “born out of trying to create a narrative that the Ban Treaty is somehow bad”.404 A number of witnesses including Mr Heisbourg, Mr Ingram and Ms Fihn said the Ban Treaty did not undermine the NPT.405 Dr Johnson said the Ban Treaty aimed “to amplify, clarify and strengthen the NPT itself by clarifying what needs to be done”.406 It was “a pathway for the implementation of Article 6”.407 Article 36 said it had been “negotiated to be legally compatible with other nuclear non-proliferation and disarmament treaties, and as an ‘effective measure’ towards fulfilling Article 6 of the NPT”. The role of the NPT in non-proliferation was “acknowledged in the TPNW’s preamble”.408

    235.Some witnesses said the Ban Treaty had created polarisation. Dr Ritchie disagreed: “This is not a matter of creating polarisation; it is a symptom of it.”409 Some witnesses said that the pressure that resulted from polarisation on nuclear possessor states could be helpful:410 “Historically”, progress had “been made on arm treaties where stakes have been high”.411

    Normative impact

    236.Ms Fihn said it was necessary “to do what we have done with biological and chemical weapons: reject them, declare them to be inhumane and stigmatise them. We must make them shameful and dishonourable”.412 Article 36 said experience showed that “building stigma over time is crucial to marginalising” the role of these weapons.413 Dr Ritchie said this represented “an effort to create the conditions for nuclear disarmament to happen”.414

    237.Article 36 said the Ban Treaty could also “have a significant impact on the private financing of nuclear weapons producers”. The “new international legal framework” of the treaty was “likely to make investors consider these companies to be an increasingly risky proposition”.415 The Northern Friends Peace Board said the treaty had caused “more than 50 financial institutions to divest from nuclear weapons” to date.416

    238.The Ban Treaty has a potential implication for the development of customary international law, defined by the International Court of Justice as “evidence of a general practice accepted as law”, which “evolves through ‘state practice’—the widespread repetition of acts, or declaration of the legality of acts, by a significant number of states and the absence of their rejection by a significant number of states”.417 Some witnesses noted that the explicit and repeated rejection of the treaty by Nuclear Weapon States represents an attempt to prevent this.418

    239.Other witnesses were sceptical about the impact of the treaty. Ms Price said that “just wishing nuclear disarmament, which I think the nuclear Ban Treaty tries to do, will not make it happen.”419 Rear Admiral Gower said the Ban Treaty sought to “shame” nuclear possessor states “through a legal statute to which they have not signed up”;420 it was “toothless”.421 Mr Heisbourg compared it to “a temperance union that does not manage to convince any alcoholics to give up the booze”.422

    240.Mr Schulte and Professor Wheeler said it was “not realistic that signatory states comprising under 40 per cent of the world’s population, and even less of its production and communications capability, will be effectively able to ‘stigmatise’ the remainder who include enormous nuclear states such as China, Russia, India, and the US and all its allies.”423 Rear Admiral Gower drew a distinction between the possible impact of the Ban Treaty on different states: it would “shame only America, France and the UK, possibly”; it was “unlikely to shame the other six countries that have nuclear weapons”, a point also made by Dr Roberts.424


    Box 6: Safeguards in the Ban Treaty

    The Ban Treaty obliges each State Party to “at a minimum, maintain its International Atomic Energy Agency safeguards obligations in force at the time of entry into force of this Treaty”. A State Party that has not concluded an IAEA safeguards agreement is obliged to agree with the IAEA to “bring into force a comprehensive safeguards agreement (INFCIRC/153 (Corrected))”.

    Source: UN General Assembly, Treaty on the Prohibition of Nuclear Weapons: http://undocs.org/A/CONF.229/2017/8 [accessed on 15 March 2019]

    241.Ms Price was critical of the Ban Treaty’s safeguards regime. She said it mandated the IAEA comprehensive safeguards agreement, which “we believe is a lesser standard than … the gold standard”—the Additional Protocol (see Box 3).425

    242.Ms Cox said the Ban Treaty did “not … account for the full range of safeguards and the long history of the body of work that has been done under the NPT ”. It gave some countries “an ‘out’ for not tackling the hard challenges”.426 The UK thought this was “dangerous”—“we want to push forward to higher standards”.427

    243.Article 36 said this was a “common criticism” of the Ban Treaty, which was incorrect.428 The treaty “legally requires parties to maintain the safeguards agreements they have”429 (see Box 6). Mr Kmentt said that for the majority of states, this was the Additional Protocol. This meant that the Ban Treaty set a stronger standard than the NPT,430 which did not require or enforce the Additional Protocol.431

    244.Dr Tzinieris said those states which did not have safeguards in place when they signed the Ban Treaty were obliged to “bring into force the Comprehensive Safeguards Agreement (INFCIRC/153 Corrected).” This ensured that “states can upgrade their safeguard standards by adopting an Additional Protocol as well as accommodate any higher standards that might be available”. Proponents of the Ban Treaty therefore argued that it “goes further than the NPT, which only obligates state parties to ‘accept safeguards’ in an unspecified agreement with the IAEA”.432


    245.Ms Price said that the Ban Treaty had “a very weak verification regime”;433 Mr Schulte and Professor Wheeler said it compared unfavourably with the NPT’s provisions.434 It “would not give anybody the assurances that disarmament had happened”.435

    246.Mr Plant said that if states discharged their obligations to both the NPT and the Ban Treaty, the inconsistency in standards would not matter. However, “if states are forum shopping, the verification requirements on non-proliferation … are much less stringent than they are under the NPT. That is a step backwards for disarmament and non-proliferation.”436

    247.Dr Tzinieris acknowledged that the Ban Treaty “provides only an outline” on verification, “with the details to be dealt with by an unspecified ‘competent national authority’”. This “lack of detail” was a recognition that “disarmament was unlikely to take place immediately”.437

    248.Mr Kmentt rejected the idea that it created “a loophole for cheating on nuclear disarmament”.438 The “absence of specific verification provisions was only logical”, because the countries with the “most expertise on verification” were nuclear possessor states, which did not participate in the negotiations. The Ban Treaty provided “space (e.g. through a future verification protocol) to include the input of adhering nuclear armed states to develop concrete verification measures, once they join the treaty.”439 Dr Johnson said in future there would be likely to be new technologies which could be used in this regard.440

    Creating discussion and focus

    249.Mr Kmentt said the treaty “tries at least to change the discourse and the unsatisfactory dynamic that we have seen … since the mid-1990s.”441 Ms Nakamitsu said “the discussions on nuclear weapons, in many European countries in particular, have become more active.” The UN had “started to receive many parliamentary delegations that are studying the new treaty”.442 The Christian Campaign for Nuclear Disarmament said the treaty had also “reinvigorate[d] civil society in the campaign against nuclear weapons and for total disarmament”.443

    The UK’s approach to the Ban Treaty

    250.Ms Price said that the UK “would not have been able to veto” the Ban Treaty,444 and “had no intention of signing it, so we did not participate.”445 The Minister said the UK did “not think the moment is there to try to abolish nuclear weapons altogether”, and thought the Ban Treaty “would compete with the NPT in a way that would not deliver as good an outcome”.446

    251.Ms Price said the UK had “strongly made clear … our concerns about its shortcomings” and “engaged with those proponents”.447 The Minister said the UK had wanted “to be frank and honest and not pretend that we support something or that it will be effective when we think otherwise”.448

    UK participation in conferences and negotiations

    252.UNA-UK said the UK’s approach to the Ban Treaty had been “surprising and concerning”. It had “failed to participate in a string of multilateral discussions on nuclear disarmament”. It described this approach as “irreconcilable with the UK’s international obligation under Article 6 of the NPT”.449 Mr Ingram said participation would have been an opportunity “to demonstrate good will and to treat Non-Nuclear Weapon States’ concerns seriously”. The Government should have shown “a little more humility by turning up to these events and voting in a way that was consistent with our policies.”450

    253.Dr Ritchie said that nuclear possessor states could have participated in the conferences and the Ban Treaty negotiations, but acknowledged that it was “highly unlikely that they were going to engage meaningfully in a process that challenges the legitimacy of nuclear weapons and nuclear deterrence”.451

    UK response to the signature of the Ban Treaty

    254.Dr Roberts regarded opposition to the treaty to be the right approach: the UK should inhibiting the treaty’s entry into force, including using “a diplomatic strategy aimed at persuading signatories not to pursue ratification at this time”.452

    255.Other witnesses took a different view. Mr Ingram said the UK had “misplayed” its rejection of the Ban Treaty.453 UNA-UK said the UK was “ill advised to … declare that the action of the significant number of 122 member states … does not constitute customary international law”.454 The UK’s response had “been picked up by a certain grouping within the international community, of a level of arrogance and a commitment to possessing nuclear weapons indefinitely, which … undermines our claim … that we are in favour of non-proliferation, both vertical and horizontal”.455

    256.Witnesses suggested possible changes to the UK’s attitude to the Ban Treaty. First, a change in tone.456 Mr Ingram said the UK should “acknowledge the frustration that lies behind the Ban Treaty and then get on with … [a] step-by-step approach to disarmament.”457

    257.Similarly, Ms Shetty suggested that the UK should continue to oppose the Ban Treaty, “but … in a more constructive and respectful manner”. It could “legitimately express its concerns about the treaty”, but in order to “try to halt the deepening polarisation”, it would have to “help to foster a more positive atmosphere in the run-up to the 2020 Review Conference and … choose to adopt a less confrontational tone in public statements with other nuclear-weapons states.”458

    258.Ms Fihn said the UK “might not be in a position to join the treaty right now” but should “stop undermining it by trying to prevent other countries from signing”.459

    259.These suggestions were consistent with Ms Nakamitsu’s view that the “divisions” between proponents and opponents of the Ban Treaty would “need to be bridged”.460 Mr Koenders took a similar view.461 Ms Nakamitsu said she and the Secretary-General “always appeal to member states to remember that there is no one path to the elimination of nuclear weapons.”462

    260.Second, the UNA-UK said that in future, the UK should “commit to attending all multilateral meetings on nuclear disarmament. Objections to the substance of any such meeting should be made from within the room.”463

    261.Third, UNA-UK said the UK “should follow Sweden’s lead … by embarking upon an independent or public consultation on the consequences of a possible future implementation” of the Ban Treaty.464 A number of witnesses including the International Campaign to Abolish Nuclear Weapons and Article 36 advocated the signature of the Ban Treaty, within varying timeframes.465

    262.The Ban Treaty has little chance of achieving its goals in the short to medium term, not least because none of the nuclear possessor states are signatories. While we welcome evidence from its proponents that it will not undermine the Nuclear Non-Proliferation Treaty, we believe the Ban Treaty risks exacerbating existing polarisation between Nuclear and Non-Nuclear Weapon States while delivering no immediate disarmament benefits. We understand and accept that the Government will remain opposed to the Ban Treaty.

    263.We also believe however that the increasing signs of division between Nuclear and Non-Nuclear Weapon States are matters of concern, and that the dissatisfaction of the Ban Treaty’s proponents with the status quo on disarmament should be taken seriously. We therefore recommend that the Government should adopt a less aggressive tone about this treaty and seek opportunities to work with its supporters towards the aims of Article 6 of the Nuclear Non-Proliferation Treaty, which concerns disarmament.

    264.More openness from the UK, as a responsible nuclear state, on the possible humanitarian impact of nuclear weapons, and a willingness to engage on developing strategies to manage the consequences of nuclear weapons use, would be welcome.

    339 Written evidence from Dr Rebecca Johnson (NPT0034) The Middle East peace process began with the Madrid Conference of 1991 and is a set of bilateral and multilateral negotiations between Israel and its Arab neighbours, addressing several concerns including regional security. The 1995 Resolution on the Middle East establishes the link between the Middle East peace process and the establishment of a WMDFZ.

    348 Written evidence from Dr Hassan Elbahtimy (NPT0032) Dr Johnson said the “formal reason” for this was “that Canada, the UK and the United States blocked consensus over the wording of a paragraph on the organization and timeline for another proposed conference to rid the Middle East of nuclear and other WMD”.

    356 Written evidence from Diana Ballestas de Dietrich (NPT0027). Dr Elbahtimy said that while nuclear weapons were “ the key hurdle”, “other weapon systems can also pose significant problems”. The use of chemical weapons in Syria “has highlighted the regional gaps in membership of the Chemical Weapons Convention”—Egypt, Israel and South Sudan are outside it. Israeli and Iranian missile programmes also “pose a challenge to a region-wide curtailment of missile capabilities”. A number of regional states have not joined the Biological and Toxin Weapons Convention, “notably Egypt, Israel and Syria”. Written evidence from Dr Hassan Elbahtimy (NPT0032)

The government of the Netherlands participated in the Humanitarian Impacts conferences and in the negotiation of the Ban Treaty, despite “virulent” opposition from other members of NATO. It then voted against it.
