Nuclear Disarmament Resource Collection


More than seven decades after their development and use during World War II, nuclear weapons continue to be the basis for a number of states' national security policies. The Treaty on the Non-Proliferation of Nuclear Weapons (NPT) prohibits non-nuclear weapon state parties from developing nuclear weapons. However, the NPT exempts five de jure nuclear weapon states (NWS) (France, the People's Republic of China, the Russian Federation, the United Kingdom, and the United States) from this ban. These five states had tested nuclear weapons before the treaty was negotiated in 1968. This "exemption" is, however, countered with a legal obligation in Article VI of the NPT for the five nuclear weapon states to fully disarm. Three other nuclear armed states—India, Israel, and Pakistan—have never joined the NPT, but possess nuclear weapons. North Korea also possesses nuclear weapons, but unlike India, Israel, and Pakistan, was previously a member of the NPT obliged not to develop nuclear weapons. North Korea withdrew from the NPT in 2003, and has tested nuclear devices multiple times since 2006 despite international condemnation and sanctions. [1]

Approximately 14,900 nuclear warheads remain in the arsenals of the nine states, approximately 4,000 of these warheads are actively deployed. [2] Five European NATO countries (Belgium, Germany, Italy, the Netherlands, and Turkey) also host approximately 150 U.S. tactical nuclear weapons as part of NATO's extended deterrence mission. [3] The United States has reduced its globally deployed tactical nuclear weapons, but tensions between Russia and NATO make further near-term reductions unlikely. [4] Large stockpiles of fissile material, including directly weapons-useable highly enriched uranium and separated plutonium, also still exists globally. [5]

The majority of countries in the world—the non-nuclear-weapon states (NNWS) — are committed to remaining free of nuclear weapons, including some countries that once possessed nuclear weapons. South Africa announced in July 1993 that it had developed a small arsenal before destroying it in 1991 in order to join the NPT as a NNWS. Belarus, Kazakhstan, and Ukraine returned large arsenals of nuclear warheads and associated delivery systems inherited from the former Soviet Union to Russia in the mid-1990s, subsequently joining the NPT as NNWS.

Other countries, including Brazil and Argentina, considered acquiring nuclear weapons, but abandoned their programs before accepting binding restraints on nuclear weapons development. Brazil and Argentina decided to join the NPT in 1994 and 1995, respectively, as NNWS.

Many NNWS are party to nuclear weapon-free zones (NWFZs), and have thereby accepted additional legal obligations not to develop, manufacture, stockpile, acquire, possess, or control any nuclear explosive devices on their territories. Today, more than 110 countries belong to NWFZ treaties. [6] Nuclear weapon-free zones are in force in South America and the Caribbean, Southeast Asia, the South Pacific, Africa, Central Asia, and Mongolia. [7]

On 7 July 2017, a United Nations conference adopted the Treaty on the Prohibition of Nuclear Weapons, the first international treaty to prohibit nuclear weapons comprehensively, including banning the development, acquisition, test, use, threat of use and possession of nuclear weapons. Although no nuclear weapons possessing states have signed the treaty, the treaty’s passage is a significant development in disarmament politics. [8]

Nuclear Disarmament and the Nuclear Nonproliferation Treaty (NPT)

The NPT prohibits nuclear weapon states from transferring nuclear weapons to, or assisting NNWS in the development of nuclear weapons. At the same time, NNWS are legally required not to receive, manufacture, or acquire nuclear weapons, and to place all their peaceful use nuclear materials and facilities under IAEA safeguards. [9]

Article VI requires all of its state parties 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." [10] The article does not specify a time frame or verification mechanism for disarmament, but it places a legal obligation on states with nuclear weapons to stop the nuclear arms race and to eventually disarm. As such, this obligation is one of the three main "pillars" of the treaty, the other two being nuclear nonproliferation and the right to use nuclear technology for peaceful purposes.

At the 1995 NPT Review and Extension Conference, state parties agreed to indefinitely extend the treaty based on a package of decisions that included Principles and Objectives for Nuclear Nonproliferation and Disarmament. This package called for a Comprehensive Nuclear Test Ban Treaty (CTBT), negotiations on a verifiable treaty banning the production of fissile material for nuclear weapons, and for "systematic and progressive efforts to reduce nuclear weapons globally." The package also included the Resolution on the Middle East, which calls for all states in the Middle East to accede to the NPT (i.e., Israel) and for action to be taken towards the "establishment of an effectively verifiable Middle East zone free of weapons of mass destruction." [11] It is likely that it would not have been possible to indefinitely extend the NPT without the concurrent commitment to this program of action.

Further building on this action plan, the 2000 NPT Review Conference, laid out 13 practical steps towards nuclear disarmament, including an "unequivocal undertaking by the nuclear weapons states to accomplish the total elimination of their nuclear arsenals." [12] This "unequivocal undertaking" was significant in that it re-committed NWS to their Article VI obligations, and for the first time in the NPT's history the NWS agreed to "the total elimination of their nuclear arsenals."

The successes of the 1995 and 2000 NPT Review Conferences were not repeated in 2005. State parties failed to adopt further substantive recommendations. [13] The failure epitomized the decade's limited progress on nuclear nonproliferation and disarmament. However, the election of Barack Obama as President of the United States heralded a new era for U.S. engagement in multilateral disarmament diplomacy. In the lead-up to the 2010 NPT Review Conference, the United States signed the New START Treaty with Russia, diminished the role of its nuclear arsenal in its new Nuclear Posture Review, and held the first in a series of Nuclear Security Summits. These initiatives demonstrated a commitment by the United States to make progress toward the ultimate goal of a "world free of nuclear weapons" as stated in President Obama’s April 2009 Prague Speech. [14]

Widely considered a success, the 2010 NPT Review Conference's final outcome document included a 64-item action plan covering the NPT's three pillars and a commitment to implement the 1995 Resolution on the Middle East. Many NNWS, and mainly the Non-Aligned Movement (NAM) countries, strongly supported the idea of negotiating a nuclear weapons convention that would delegitimize nuclear weapons and eliminate them within a clear timeframe. Although these ideas were opposed by the NWS, the final document noted the Secretary General's five-point proposal for nuclear disarmament, including consideration of negotiations on a nuclear weapons convention. [15] The action plan set clear benchmarks for the implementation of Article VI.

The 2015 NPT Review Conference was unsuccessful in producing a final outcome document. The most contentious issues were nuclear disarmament and discussions of a Middle East WMD-Free Zone. The Review Conference highlighted deep divisions between the NWS and NNWS. The discussion on the humanitarian approach to nuclear disarmament drew a wide range of support, but was also a source of tension and disagreement. While disarmament issues prompted the most contentious debates among states parties, in the end, the disagreement over convening a conference on a Middle East WMD-Free Zone prevented the Review Conference from adopting a final document. [16]

Has Any Progress Been Made Towards Disarmament?

Gauging progress towards nuclear disarmament is complicated because shifts both in numbers of weapons and in the overarching policies governing these weapons are relevant. In terms of quantitative reductions, measurable steps have been undertaken by key NWS both unilaterally and bilaterally. The NWS collectively reduced the size of their nuclear arsenals from over 70,000 warheads at the height of the Cold War to approximately 14,200 by 2018. [17] These reductions have been carried out unilaterally by at least four NWS, as well as through bilateral legally binding arrangements between the United States and the Soviet Union/Russian Federation.

The United States has reduced its stockpile by about 87% from a Cold War peak of 31,255 warheads in 1967, to the current stockpile of approximately 4,000 operational and reserved warheads. [18] While France has reduced its arsenal unilaterally, and the United Kingdom announced ambitious reductions to its arsenal in 2010, both states plan to maintain a credible nuclear deterrent for the foreseeable future. [19] China is the only NWS that appears to be increasing its nuclear stockpile, albeit slowly. [20] Experts estimate that India and Pakistan have been rapidly expanding their nuclear arsenals and capabilities. [21]

Bilateral Efforts

There is an extensive precedent for bilateral U.S.-USSR/Russia arms control. Since 1969, the United States and Russia have been limiting/reducing their strategic nuclear arsenals through bilateral treaties. These arrangements began modestly with SALT I, which only limited the number of ICBMs and SLBMs, leaving both nations to increase numbers of both bombers and warheads. SALT I also produced the ABM treaty in 1972, which banned nationwide strategic missile defenses (the U.S. withdrew from the ABM treaty in 2002). [22] Following the Cold War, START I (enacted in 1994), placed limitations on the numbers of deployed launchers and, for the first time, warheads. While both START II and III failed to materialize, the United States and Russia negotiated the Strategic Offensive Reductions Treaty (SORT) in 2002. SORT provided for a significant reduction of deployed strategic nuclear warheads in each arsenal to 1,700 - 2,200. However, SORT was often criticized for having a weak verification regime that relied on the START I regime. Fears that this treaty and the START agreement would expire without anything to fill the void were allayed with the signing of the New START Treaty in April 2010, and its subsequent entry into force in February 2011. New START limits the United States and Russia to no more than 1,550 deployed nuclear warheads and 700 launchers by 2018. [23] Both the United States and Russia met those limits on schedule, according to a February 2018 information exchange. [24]

New START expires in 2021, and tensions between the U.S. and Russia complicate negotiations for further strategic reductions. [25] Both countries are pursuing new types of weapons: at a speech in March 2018, Russian President Vladimir Putin announced several new nuclear weapon delivery systems, including an intercontinental cruise missile, while U.S. President Donald Trump’s 2018 Nuclear Posture Review called for lower-yield warheads for submarine-launched ballistic missiles and submarine-launched cruise missiles. [26]

Multilateral Efforts

Attempts at negotiating legally binding multilateral nuclear disarmament treaties have proven challenging. The United Nations established the Conference on Disarmament (CD) as the sole multilateral disarmament-negotiating forum in 1979. The 65-member, consensus-ruled body has only negotiated one treaty related to nuclear disarmament over the past 30 years, the Comprehensive Nuclear Test-Ban Treaty (CTBT) in 1996. Widely considered to be a milestone towards nuclear disarmament, the CTBT would prohibit all nuclear testing. Nineteen years after it opened for signature the CTBT has yet to enter into force. Entry into force of the CTBT requires ratification by all states with nuclear power reactors and/or research reactors (in 1996), known as Annex II states. Eight of these countries, including the United States and China, have yet to ratify. [27]

Since the conclusion of CTBT negotiations in 1996, the CD has been locked in a perpetual stalemate. Negotiations on a Fissile Material Cut-Off Treaty (FMCT) have not commenced even 18 years after agreement on the Shannon Mandate (a mandate adopted by the CD in 1995 that proposed the negotiation of a treaty banning the production of fissile material [28]). Many consider an FMCT ripe for negotiation and the next logical step toward nuclear disarmament. In 2009, CD member states agreed upon a program of work, CD/1864, but were unable to implement it due to procedural blockages. [29] Over the past three years Pakistan has emerged as the single detractor, objecting on the basis of national security and substance. Pakistan fears its national security will be at risk if its rival and neighbor, India, is left with a larger existing fissile material stockpile, and therefore has the capability to continue to produce nuclear weapons after the implementation of the treaty. [30] Pakistan argues that an FMCT would not address existing stockpiles of fissile materials, and would therefore further nonproliferation but not disarmament. [31]

Pakistan's conceptual argument taps into the longstanding confrontation between the nuclear weapon "haves and have nots." Paradoxically, as Non-Aligned Movement (NAM) members, Pakistan and India vocally support nuclear disarmament while simultaneously increasing their nuclear arsenals and delivery systems. Many NAM members and other NNWS believe that the NWS are not fully meeting their Article VI obligation. [32] Apart from the bilateral negotiations on New START, there have been no negotiations or efforts on disarmament measures since the conclusion of the CTBT negotiations. Moreover, unilateral and U.S.-Russia reductions have been perceived by many NNWS as nothing more than efforts to streamline existing nuclear arsenals, rather than steps towards complete nuclear disarmament. Perhaps most notably, all nuclear weapon states are pursuing some degree of nuclear modernization. [33]

Other Significant Efforts to Promote Nuclear Disarmament

Certain national governments and members of civil society have cooperated on initiatives to promote progress towards a world free of nuclear weapons. A progressive approach to promote nuclear disarmament was taken by the New Agenda Coalition (NAC). In June 1998, foreign ministers from Brazil, Egypt, Ireland, Mexico, New Zealand, South Africa, Slovenia, and Sweden (the latter two eventually withdrawing), issued a statement calling for a new nuclear disarmament agenda, "Toward a Nuclear-Weapons-Free World: Time for a New Agenda." The NAC played an instrumental role in convincing the NWS to agree to the thirteen practical steps towards nuclear disarmament in the final document of the 2000 NPT Review Conference.

Around the same time, the Middle Powers Initiative was established in support of NNWS efforts to reduce and eliminate worldwide nuclear weapons arsenals. Following the failure of the 2005 NPT Review Conference, the Middle Powers Initiative launched the "Article VI Forum" in October 2005 to examine the legal, technical, and political requirements to fulfill nonproliferation and disarmament commitments for a nuclear weapon-free world. [34]

Several independent international commissions have played an important role by providing expert recommendations in the form of nuclear disarmament action plans. These commissions include the 1996 Canberra Commission on the Elimination of Nuclear Weapons sponsored by the Australian Government, the 1998 Tokyo Forum for Nuclear Nonproliferation and Disarmament sponsored by the Japanese government, and the Weapons of Mass Destruction (WMD) Commission.

The Weapons of Mass Destruction Commission was established in 2003 amidst stagnation on nuclear disarmament and serious challenges facing the nuclear nonproliferation regime. It issued a report that concluded "the nuclear weapon states no longer seem to take their commitment to nuclear disarmament seriously-even though this was an essential part of the NPT bargain, both at the treaty's birth in 1968 and when it was extended indefinitely in 1995." [35] The report offered several recommendations for multilateral cooperative actions to counter this trend, including a call to adhere to disarmament obligations, ratify the CTBT and FMCT, and change nuclear postures.

An initiative undertaken by four former high- ranking U.S. officials — George Shultz, William Perry, Henry Kissinger, and Sam Nunn — created significant momentum for a world free of nuclear weapons. The four statesmen originally published their proposals in a 4 January 2007 Wall Street Journal op-ed, "A World Free of Nuclear Weapons," followed a year later by another op-ed, "Toward a Nuclear Weapon Free World." This initiative came at a critical juncture, with the international community facing new and ongoing nuclear threats, when no new significant arms control reductions between the United States and Russia were being pursued. [36] The four statesmen called for U.S. leadership and global cooperation on nonproliferation.

In 2008, Japan and Australia established the International Commission on Nuclear Non-Proliferation and Disarmament (ICNND) to reinvigorate international nonproliferation and disarmament efforts and to help shape a consensus at the then-upcoming 2010 NPT Review Conference. Japan and Australia joined together again in September 2010 to create the Nonproliferation and Disarmament Initiative (NPDI). The group consisted of twelve countries (Australia, Canada, Chile, Germany, Japan, Mexico, the Netherlands, Nigeria, the Philippines, Poland, Turkey and the United Arab Emirates) that aimed to facilitate the implementation of the measures from the consensus document of the 2010 NPT Review Conference. [37] In April 2014, the NPDI adopted the "Hiroshima Declaration" that contained concrete proposals for both disarmament and nonproliferation, including calls to negotiate the FMCT, increase nuclear safety and safeguards, encourage the entry into force of the CTBT, and increase transparency in disarmament reporting. [38] However, as the NPDI consists mainly of U.S. allies protected by U.S. extended nuclear deterrence, its disarmament approach is often considered more moderate than the ones of the NAC or NAM that call for delegitimizing nuclear weapons.

The Humanitarian Initiative for Nuclear Disarmament

The humanitarian impact of nuclear weapons has increasingly drawn attention. The 2010 NPT Review Conference final document expressed concern about the humanitarian consequences of any use of nuclear weapons. [39] A coalition of state parties and civil society groups has continued to push this issue, resulting in three international conferences on the humanitarian impact of nuclear weapons in Oslo, Nayarit, and Vienna, where there have been discussions about negotiating a prohibition against nuclear weapons. [40] The third conference in Vienna produced the Humanitarian Pledge (formerly the "Austrian Pledge"), which over 100 countries have supported. [41] The statement emphasized that nuclear weapons should never be used again "under any circumstances." [42] The nuclear weapon states did not participate in the first two conferences, but the United States and United Kingdom sent representatives to attend the third conference in Vienna. [43] Another group of state parties, mainly consisting of NNWS who rely on U.S. extended nuclear deterrence has pushed an alternative humanitarian pledge that is less extensive. [44]

To some extent countering the humanitarian initiative, the five NPT-recognized NWS have taken a so-called "P5 step," affirming that they intend to continue to seek progress on the step-by-step approach to nuclear disarmament as opposed to aiming to eliminate nuclear weapons within a specific timeframe. [45] The P-5 states have held seven conferences to increase dialogue and transparency in disarmament progress. For that purpose, at the 2015 Review Conference each of the P5 states submitted its national report, and completed a first edition of a glossary of key nuclear terms. However, most of the NNWS, especially NAM countries and civil society members, are critical about the P5 process since it is generally perceived that this process has not contributed to the actual reduction of nuclear weapons. [46]

Since the CD remains stalemated and the five NPT-recognized NWS have continually refused to participate in other multilateral negotiations on nuclear disarmament, the international community's ability to advance nuclear disarmament is highly limited. [47]

The important role of disarmament and nonproliferation education in promoting and facilitating nuclear disarmament must also be recognized, as evinced by the adoption of UN General Assembly Resolution 57/60 in November 2002, which reaffirms the need to support education in the field and include the topic in future meetings. [48] Education and training will remain vital to the success of future disarmament initiatives.

Nuclear Weapons Ban Treaty

After the failure of states parties to the 2015 NPT Review Conference to reach consensus, many countries sought to press forward the nuclear disarmament agenda in the United Nations General Assembly. Over the course of three sessions in 2016, an Open-Ended Working Group (OEWG) of states recommended that the UN General Assembly convene a conference in 2017 to "negotiate a legally binding instrument to prohibit nuclear weapons, leading toward their total elimination." [49] On 27 October 2016, The First Committee of the UN General Assembly voted to adopt the resolution to convene the nuclear ban conferenence, and the full UN General Assembly followed suit on 23 December 2016. [50]

On 7 July 2017 the Treaty on the Prohibition of Nuclear Weapons was adopted by a recorded vote of 122 in favor to one against (the Netherlands), with one abstention (Singapore). [51] Proponents of the treaty believe that it can strengthen norms against nuclear weapons and stigmatize such weapons. Opponents, including nuclear possessing states and states under extended nuclear deterrence, boycotted the negotiations (with the exception of the Netherlands). NWS have been sharply critical of the treaty process; France, the UK, and the U.S. released a joint statement asserting that the treaty deepens the division between nuclear weapon states and non-nuclear weapon states, and that they do not “intend to sign, ratify or ever become party to it.” [52] Russia used similar language, claiming the treaty would “have a destabilizing effect on the nonproliferation regime.” [53] However, the majority of the international community welcomed the adoption of the treaty as a significant achievement. In recognition of the role of civil society and grass-roots activism in the treaty’s passage, the International Campaign to Abolish Nuclear Weapons (ICAN) was awarded the 2017 Nobel Peace Prize for its “ground-breaking efforts to achieve a treaty-based prohibition of nuclear weapons.” [54] As part of an effort to build bridges between parties with opposing views, the Japanese government established the “Group of Eminent Persons for Substantive Advancement of Nuclear Disarmament,” and submitted its recommendations to the second session of the PrepCom for the 2020 NPT Review Conference.
