This book studies the impact of the nuclear revolution on the course of the rivalry between the former USSR and the USA. It explains why it has been so different from great power rivalry in prenuclear times, in avoiding war and leading first to a co-operative relationship and then ending peacefully. The book analyses four aspects of the nuclear revolution: reciprocal restraint, security co-operation, the deadlock of nuclear strategy (including strategic defence) and common deterrence.Introduction - Peace and War - Nuclear Danger and the Development of Reciprocal Restraint - The Deadlock of Nuclear Strategy - The Development of Common Deterrence - Will the Nuclear Age Last? - The Nuclear Revolution and Global Pacification - Bibliography - Index
