This book, first published in 1983, examines the role that arms control has to play, alongside defence and deterrence, in stabilising East-West relations and reducing tensions during the Cold War. Arms control agreements were designed in the attempt to achieve parity between the nuclear forces of the superpowers, without making war more likely. A danger of confrontation between the USSR and the USA came from their involvement in Third World conflicts, and this arena is also discussed. The diplomatic approaches of the Soviet Union, the Third World and the West, and their aims in arms control, are also analysed.
