In this study, CISAC tackles the technical dimensions of a longstanding controversy: To what extent could existing and plausibly attainable measures for transparency and monitoring make possible the verification of all nuclear weaponsâ€"strategic and nonstrategic, deployed and nondeployedâ€"plus the nuclear-explosive components and materials that are their essential ingredients? The committee's assessment of the technical and organizational possibilities suggests a more optimistic conclusion than most of those concerned with these issues might have expected.

Nuclear disarmament is firmly back on the international agenda. But almost all current thinking on the subject is focused on the process of reducing the number of weapons from thousands to hundreds. This rigorous analysis examines the challenges that exist to abolishing nuclear weapons completely, and suggests what can be done now to start overcoming them. The paper argues that the difficulties of 'getting to zero' must not preclude many steps being taken in that direction. It thus begins by examining steps that nuclear-armed states could take in cooperation with others to move towards a world in which the task of prohibiting nuclear weapons could be realistically envisaged. The remainder of the paper focuses on the more distant prospect of prohibiting nuclear weapons, beginning with the challenge of verifying the transition from low numbers to zero. It moves on to examine how the civilian nuclear industry could be managed in a nuclear-weapons-free world so as to prevent rearmament. The paper then considers what political-security conditions would be required to make a nuclear-weapons ban enforceable and explores how enforcement might work in practice. Finally, it addresses the latent capability to produce nuclear weapons that would inevitably exist after abolition, and asks whether this is a barrier to disarmament, or whether it can be managed to meet the security needs of a world newly free of the bomb.

This book fills a clear gap in the literature for a technically-focused book covering nuclear proliferation and related issues post-9/11. Using a concept-led approach which serves a broad readership, it provides detailed overview of nuclear weapons, nuclear proliferation and international nuclear policy. The author addresses topics including offensive and defensive missile systems, command and control, verification, weapon effects, and nuclear testing. A chronology of nuclear arms is presented including detailed discussion of the Cold War, proliferation, and arms control treaties. The book is tailored to courses on nuclear proliferation, and the general reader will also find it a fascinating introduction to the science and strategy behind international nuclear policy in the modern era.

This two-volume book provides a comprehensive analysis of the lawfulness of the use of nuclear weapons, based on existing international law, established facts as to nuclear weapons and their effects, and nuclear weapons policies and plans of the United States. Based on detailed analysis of the facts and law, Professor Moxley shows that the United States’ arguments that uses of nuclear weapons, including low-yield nuclear weapons, could be lawful do not withstand analysis. Moxley opens by examining established rules of international law governing the use of nuclear weapons, first analyzing this body of law based on the United States’ own statements of the matter and then extending the analysis to include requirements of international law that the United States overlooks in its assessment of the lawfulness of potential nuclear weapons uses. He then develops in detail the known facts as to nuclear weapons and their consequences and U.S. policies and plans concerning such matters. He describes the risks of deterrence and the existential nature of the effects of nuclear war on human life and civilization. He proceeds to pull it all together, applying the law to the facts and demonstrating that known nuclear weapons effects cannot comply with such legal requirements as those of distinction, proportionality, necessity, precaution, the corollary requirement of controllability, and the law of reprisal. Moxley shows that, when the United States goes to apply international law to potential nuclear weapons uses, it distorts the law as it has itself articulated it, overlooks law in such areas as causation, risk analysis, mens rea, and per se rules, and disregards known risks as to nuclear weapons effects, including radioactive fallout, nuclear winter, electromagnetic pulses, and potential escalation. He then shows that the policy of deterrence is unlawful because the use of such weapons would be unlawful. Moxley urges that the United States and other nuclear weapons States take heed of the requirements of international law as to nuclear weapons threat and use. He argues that law can be a positive force in society’s addressing existential risks posed by nuclear weapons and the policy of nuclear deterrence.

In recent years, senior policy officials have highlighted increased signs of convergence between terrorism and unconventional (CBRN) weapons. Terrorism now involves technologies available to anyone, anywhere, anytime, deployed through innovative solutions. This indicates a new and more complex global security environment with increasing risks of terrorists trying to acquire and deploy a CBRN (Chemical Biological Radiological Nuclear) attack. This book addresses the critical importance of understanding innovation and decision-making between terrorist groups and unconventional weapons, and the difficulty in pinpointing what factors may drive violence escalation. It also underscores the necessity to understand the complex interaction between terrorist group dynamics and decision-making behaviour in relation to old and new technologies. Unconventional Weapons and International Terrorism seeks to identify a set of early warnings and critical indicators for possible future terrorist efforts to acquire and utilize unconventional CBRN weapons as a means to pursue their goals. It also discusses the challenge for intelligence analysis in handling threat convergence in the context of globalisation. The book will be of great interest to students of terrorism studies, counter-terrorism, nuclear proliferation, security studies and IR in general.

The articles and essays in this volume consider the problem of international terrorism from an international legal perspective. The articles address a range of issues starting with the dilemma of how to reach agreement on what constitutes terrorism and how to encapsulate this in a legitimate definition. The essays move on to examine the varied responses to terrorism by states and international organisations. These responses range from the suppression conventions of the Cold War, which were directed at criminalising and punishing various manifestations of terrorism, to more coercive, executive-led responses. Finally, the articles consider the role of the Security Council in developing legal regimes to combat terrorism, for example by the use of targeted sanctions, or by general legislative measures. An evaluation of the contribution of the sum of these measures to the goals of peace and security as embodied in the UN Charter is central to this collection.
