Despite the ongoing drawdown of strategic forces under the terms of START, both the United States and Russia maintain large arsenals of nuclear weapons poised for immediate launch. Under the most optimistic current scenarios, these arsenals will remain very large and launch-ready for more than a decade. This book, by a distinguished group of coauthors, critically evaluates the current policy of retaining and operating large nuclear arsenals. It reviews U.S. nuclear doctrine and strategy, and the role of nuclear weapons in deterring aggression by former Cold War adversaries and other countries with weapons of mass destruction. The risks of inadvertent as well as deliberate nuclear attack are assessed. The authors argue that small arsenals (low hundreds) on low alert satisfy all justifiable requirements for nuclear weapons. They present a blueprint for making deep cuts in U.S. and Russian deployments, and for lowering their alert level. They explain the implications of shifting to small arsenals for further constraining anti-ballistic missile defenses, strengthening verification, and capping or reducing the nuclear arsenals of China, France, and Britain as well as the threshold nuclear states. The political challenges and opportunities, both domestic and international, for achieving deep reductions in the size and readiness of nuclear forces are analyzed by the authors and by distinguished experts from other countries. The coauthors are Bruce Blair, Jonathan Dean, James Goodby, Steve Fetter, Hal Feiveson, George Lewis, Janne Nolan, Theodore Postol, and Frank von Hippel. An appendix with international perspectives by Li Bin (China), Alexei Arbatov (Russia), Therese Delpech (France), PervezHoodbhoy (Pakistan), Shai Feldman (Israel), Harald Mueller (Germany), and Zia Mian and M.V.

A new approach to nuclear disarmament, nonproliferation, and the prevention of nuclear terrorism that focuses on controlling the production and stockpiling of nuclear materials. Achieving nuclear disarmament, stopping nuclear proliferation, and preventing nuclear terrorism are among the most critical challenges facing the world today. Unmaking the Bomb proposes a new approach to reaching these long-held goals. Rather than considering them as separate issues, the authors-physicists and experts on nuclear security-argue that all three of these goals can be understood and realized together if we focus on the production, stockpiling, and disposal of plutonium and highly enriched uranium-the fissile materials that are the key ingredients used to make nuclear weapons. The authors describe the history, production, national stockpiles, and current military and civilian uses of plutonium and highly enriched uranium, and propose policies aimed at reducing and eventually eliminating these fissile materials worldwide. These include an end to the production of highly enriched uranium and plutonium for weapons, an end to their use as reactor fuels, and the verified elimination of all national stockpiles.
