Richard Ned Lebow spells out the implications of historical experience for American perceptions of the place of crisis management in superpower strategic relations. identifying and discussing three reasons for the outbreak of World War I--preemption, loss of control, and miscalculated escalation--he argues that all three are equally serious threats to peace and survival. He documents how psychological stress in past crises has induced erratic, dysfunctional behavior from national leaders, even paralysis. A nuclear crisis, he argues, would generate even more acute stress because of the unprecedented destructiveness of nuclear weapons and the extreme time pressure that leaders are likely to face.
