No more important issue faces us today than the future success of efforts to manage and control nuclear arsenals. Reykjavik and Beyond represents the careful consideration of this subject by a group of experts deeply involved in arms control. The authors consider what changes in force structures, strategic thought, and political relations would be necessary to make possible large reductions in the superpowers’ nuclear arsenals. They also examine how very deep cuts would affect other aspects of the military balance and the political and international order more broadly.
