Thirty years ago, President Eisenhower's Atoms for Peace proposal to the United Nations provided the basis for development of nuclear cooperation, trade, and nonproliferation policy in the noncommunist world. Ever since its inception, however, the policy has sparked widespread debate, and it remains controversial today. Exploring the past, present, and future significance of Atoms for Peace, the contributors to this volume analyze the future role of the United States in international affairs, the nature of controls over nuclear cooperation and trade, the scope and limitations of international cooperation in nuclear energy and nonproliferation matters, and the prospects for multinational and international institutional measures to achieve these ends.
