The debate about appropriate purposes and policies for U.S. nuclear weapons has been under way since the beginning of the nuclear age. With the end of the Cold War, the debate has entered a new phase, propelled by the post-Cold War transformations of the international political landscape. This volume--based on an exhaustive reexamination of issues addressed in The Future of the U.S.-Soviet Nuclear Relationship (NRC, 1991)--describes the state to which U.S. and Russian nuclear forces and policies have evolved since the Cold War ended. The book evaluates a regime of progressive constraints for future U.S. nuclear weapons policy that includes further reductions in nuclear forces, changes in nuclear operations to preserve deterrence but enhance operational safety, and measures to help prevent proliferation of nuclear weapons. In addition, it examines the conditions and means by which comprehensive nuclear disarmament could become feasible and desirable.

On January 27, 2017, President Donald Trump directed Secretary of Defense James Mattis to initiate a new Nuclear Posture Review (NPR). The President made clear that his first priority is to protect the United States, allies, and partners. He also emphasized both the long-term goal of eliminating nuclear weapons and the requirement that the United States have modern, flexible, and resilient nuclear capabilities that are safe and secure until such a time as nuclear weapons can prudently be eliminated from the world.The United States remains committed to its efforts in support of the ultimate global elimination of nuclear, biological, and chemical weapons. It has reduced the nuclear stockpile by over 85 percent since the height of the Cold War and deployed no new nuclear capabilities for over two decades. Nevertheless, global threat conditions have worsened markedly since the most recent 2010 NPR, including increasingly explicit nuclear threats from potential adversaries. The United States now faces a more diverse and advanced nuclear-threat environment than ever before, with considerable dynamism in potential adversaries' development and deployment programs for nuclear weapons and delivery systems.

Originally published in 1983, this book presents both the technical and political information necessary to evaluate the emerging threat to world security posed by recent advances in uranium enrichment technology. Uranium enrichment has played a relatively quiet but important role in the history of efforts by a number of nations to acquire nuclear weapons and by a number of others to prevent the proliferation of nuclear weapons. For many years the uranium enrichment industry was dominated by a single method, gaseous diffusion, which was technically complex, extremely capital-intensive, and highly inefficient in its use of energy. As long as this remained true, only the richest and most technically advanced nations could afford to pursue the enrichment route to weapon acquisition. But during the 1970s this situation changed dramatically. Several new and far more accessible enrichment techniques were developed, stimulated largely by the anticipation of a rapidly growing demand for enrichment services by the world-wide nuclear power industry. This proliferation of new techniques, coupled with the subsequent contraction of the commercial market for enriched uranium, has created a situation in which uranium enrichment technology might well become the most important contributor to further nuclear weapon proliferation. Some of the issues addressed in this book are: A technical analysis of the most important enrichment techniques in a form that is relevant to analysis of proliferation risks; A detailed projection of the world demand for uranium enrichment services; A summary and critique of present institutional non-proliferation arrangements in the world enrichment industry, and An identification of the states most likely to pursue the enrichment route to acquisition of nuclear weapons.

The 1968 Nuclear Non-proliferation Treaty has proven the most complicated and controversial of all arms control treaties, both in principle and in practice. Statements of nuclear-weapon States from the Cold War to the present, led by the United States, show a disproportionate prioritization of the non-proliferation pillar of the Treaty, and an unwarranted underprioritization of the civilian energy development and disarmament pillars of the treaty. This book argues that the way in which nuclear-weapon States have interpreted the Treaty has laid the legal foundation for a number of policies related to trade in civilian nuclear energy technologies and nuclear weapons disarmament. These policies circumscribe the rights of non-nuclear-weapon States under Article IV of the Treaty by imposing conditions on the supply of civilian nuclear technologies. They also provide for the renewal and maintaintenance, and in some cases further development of the nuclear weapons arsenals of nuclear-weapon States. The book provides a legal analysis of this trend in treaty interpretation by nuclear-weapon States and the policies for which it has provided legal justification. It argues, through a close and systematic examination of the Treaty by reference to the rules of treaty interpretation found in the 1969 Vienna Convention on the Law of Treaties, that this disproportionate prioritization of the non-proliferation pillar of the Treaty leads to erroneous legal interpretations in light of the original balance of principles underlying the Treaty, prejudicing the legitimate legal interests of non-nuclear-weapon States.

Nuclear Weapons under International Law is a comprehensive treatment of nuclear weapons under key international law regimes. It critically reviews international law governing nuclear weapons with regard to the inter-state use of force, international humanitarian law, human rights law, disarmament law, and environmental law, and discusses where relevant the International Court of Justice's 1996 Advisory Opinion. Unique in its approach, it draws upon contributions from expert legal scholars and international law practitioners who have worked with conventional and non-conventional arms control and disarmament issues. As a result, this book embraces academic consideration of legal questions within the context of broader political debates about the status of nuclear weapons under international law.

A unique and indispensible work that serves both as a basic introduction to the disarmament scene and a reference book for experts' - "Disarmament Times " The revised and updated edition of Arms Control: The New Guide to Negotiations and Agreements contains the most authoritative and comprehensive survey ever published of the documents related to arms control.
