This book, first published in 1990, examines the nature and causes of the changes to Soviet national security policy under Gorbachev. Changes in leadership and institutional arrangements, economic policy, ideology and military involvement all fostered new patterns of cooperation and competition. Authors look at the historical, economic and cultural contexts of change and proceed to a discussion of change agents, such as modernization, technology and domestic politics. Specific components of foreign and military policy, such as arms control and relations with Western Europe, the Warsaw Pact and the Third World, are also examined.
