“The major prize”: apartheid South Africa’s accession to the Treaty on the Non-Proliferation of Nuclear Weapons, 1988–91

ABSTRACT

This article focuses on the final years of South Africa’s nuclear-weapon program, particularly on the decision-making process leading up to the signature of the 1968 Treaty on the Non-Proliferation of Nuclear Weapons (NPT) by the South African government in 1991. In August 1988, after two decades of defiance, negotiations between the apartheid government and the NPT depository powers (the United Kingdom, the United States, and the Soviet Union) ensued at the International Atomic Energy Agency (IAEA) in Vienna. Despite South Africa being the only state to give up its indigenously developed nuclear weapons and subsequently join the nonproliferation regime, little is known about how the national position on NPT accession and IAEA safeguards evolved. Research carried out in multiple archives using hitherto untapped primary sources and interviews with key actors from several countries show how domestic and regional political dynamics influenced Pretoria’s position on entering the nonproliferation regime. In the process, the F.W. de Klerk government managed to skillfully exploit international proliferation fears to advance its own agenda, thereby connecting South African NPT accession with that of the neighboring Frontline States coalition of Angola, Mozambique, Tanzania, Zambia, and Zimbabwe.     

Japan and Extended Nuclear Deterrence: Security and Non-proliferation

ABSTRACT

To an observer, Japan’s approach to nuclear weapons can appear confused and contradictory. The only country to have been attacked with nuclear weapons is variously described as a pacifist and non-nuclear nation and as a proliferation threat. These widely varied and conflicting conclusions are understandable given that conflicting messages are sent by senior figures. However Japan’s stance is in fact a coherent, if not uncomplicated, response both to its security needs and to domestic public opinion. However, the security provided by US extended nuclear deterrence underlines and enables this approach. The key policies and decisions were taken in both Washington and Tokyo between China’s first nuclear test (1964) and Japan’s ratification of the Nuclear Non-Proliferation Treaty (1976). How the United States came to offer this additional security guarantee to Japan and how Japan came to rely upon it underscore this complex stance and are crucial to understanding a longstanding and ongoing security arrangement and source of stability and security in northeast Asia.     

论自主武器军控的国际法及政策要点

美国退出《中导条约》与俄美关系发展走向

2018年10月,美国宣布单方面退出《中导条约》。《中导条约》是美苏两国在冷战后期达成的,并得到了切实执行的条约,对于维护冷战后全球战略平衡发挥了至关重要的作用。冷战后,俄美曾经企图将《中导条约》多边化,构建俄美新型战略关系,但最终反目成仇,使得俄美关系严重倒退,并迈入新的相互战略遏制的时代。     

Beyond Pessimism: Why the Treaty on the Non-Proliferation of Nuclear Weapons Will Not Collapse

This article questions the predominantly pessimistic assessments over the future of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT). After analysing available evidence on states’ interests and interactions within the NPT’s framework, it argues that several negative expectations are unwarranted. Conversely, the article identifies three potentially threatening scenarios. Therefore, it scrutinizes the likely impact of reactive nuclear proliferation; analyses the probability of significant actors challenging the existent nuclear architecture; and explores whether the treaty’s enforcement might soon be diluted. The article concludes the NPT is unlikely to face fundamental threats in the foreseeable future.     

GLOBALIZING REAGAN'S INF TREATY

When it was concluded more than a quarter century ago, the Intermediate-Range Nuclear Forces (INF) Treaty between the United States and the Soviet Union was hailed as a disarmament watershed, eliminating entire classes of nuclear missiles from the arsenals of the arms-racing Cold War superpowers. Over the intervening decades, there have been repeated calls to convert this legacy treaty into a new international norm against nuclear and missile proliferation by broadening it into a global prohibition on ground-launched ballistic and cruise missiles with ranges between 500 and 5,500 kilometers. Indeed, variations on this proposal have been knocking around for so long and with so little success that the entire concept has come to be dismissed by many knowledgeable insiders as something of a farce. Looking beyond its inauspicious pedigree, however, this viewpoint suggests that the time is opportune for Washington to give the idea a fresh look. Drawing on a detailed review of the history of “Global INF” and an analysis of the contemporary context, the author recommends that the Obama administration consider a simple declaratory approach that promises modest initial benefits, avoids previous and foreseeable pitfalls, and plausibly lays a solid foundation for achieving significant long-term progress.     

VERIFIABILITY,RELIABILITY, AND NATIONAL SECURITY

The rejection of the Comprehensive Nuclear-Test-Ban Treaty (CTBT) by the U.S. Senate in October 1999 could have been avoided, and the consequences of that vote still loom in the minds of supporters of the treaty. President Barack Obama has embraced the vision of a world free of nuclear weapons, and a key element of the Obama administration's arms control agenda is delivering on U.S. CTBT ratification. In order to secure the two-thirds majority in the Senate necessary to ratify the treaty, senators that remain skeptical of nuclear disarmament must also be convinced that the entry into force of the CTBT is in the national security interest of the United States. This article provides an analysis of the issues surrounding U.S. CTBT ratification divided into three segments—verifiability of the treaty, reliability of the U.S. stockpile, and the treaty's impact on U.S. national security—and concludes that CTBT ratification serves the security objectives of the United States. The CTBT constitutes an integral component of the multilateral nonproliferation architecture designed to prevent the proliferation of nuclear weapons, and it constrains the qualitative development of nuclear weapons, thereby hindering efforts by states of concern to develop advanced nuclear weapons.     

ACHIEVING THE VISION OF THE NPT

This article assesses the prospects for a strategy of incrementalism to lead to achievement of the core bargain of the Treaty on the Non-Proliferation of Nuclear Weapons: non-nuclear weapon states' nuclear nonproliferation in exchange for nuclear weapon states' nuclear disarmament to the point of “global zero.” Game theory, prospect theory, and liberal international theory are used to evaluate the potential of a strategy of incrementalism. While separately each has insights to offer, it is when all three theoretical approaches are used in tandem that meaningful explanatory gains emerge. The article concludes that incrementalism probably cannot lead to complete nonproliferation and global nuclear zero. Instead, signal events (as described by prospect theory) are needed to “punctuate” incremental processes in negotiations (best explained by liberal international theory) in order to move past hindrances such as international structural constraints (exemplified by game theory) and the conservative risk-taking propensities of state elites (described by prospect theory).     

The Odyssey of the Comprehensive Nuclear-Test-Ban Treaty

This study examines the failures of the William J. Clinton and Barack Obama administrations to secure ratification of the Comprehensive Nuclear-Test-Ban Treaty (CTBT). It applies an integrated analytical framework for assessing treaty ratification that builds upon previous research in order to understand why the Clinton administration failed to achieve CTBT ratification in 1999 and why the Obama administration has so far failed to advance the treaty in the Senate. The study concludes that CTBT ratification, despite Obama administration pledges of support, remains highly unlikely. Finally, the study analyzes the common domestic political factors present in both cases and suggests areas for further research.
