In the last year the world has witnessed changes in East-West relations that would have been unthinkable only a short time ago. The Berlin Wall has crumbled, Eastern Europe has thrown out its authoritarian leaders, and the Soviet Union itself has undergone dramatic changes in political structure and foreign policy. The U.S. public no longer regards the Eastern Bloc as the principal threat to national security. Yet even with the undeniable thaw in the Cold War many of the oldscenarios for "World War III" remain as plausible as they were in the past, and new sources of instability could arise from ethnic conflicts, economic competition, or other sources. The second volume of Behavior, Society, and Nuclear War addresses the potential causes of nuclear war within the contextof this changing political landscape. As in the first volume of this series, leading scholars review specific behavioral and social phenomena and processes that may be critical in determining war and peace-how foreign policy decision are made, the role of arms races, and the activities of third-party moderators. Volume Two also explores the effects of changing international conditions on the potential for the growing importance of conflicts between small powers, the possibility thattechniques of reassurance can supplement deterrence, and the sources of moderation in Soviet security policy. Informed by the most up-to-date scholarship, Behavior, Society, and Nuclear War will be essential reading for anyone interested in international relations, disarmament, political science, andsociology.
