This is an authoritative and comprehensive history of the Fifty Years' war and the relationship that dominated world politics in the second half of the twentieth century. For fifty years relations between the United States and the Soviet Union were deciding factors in international affairs. Available for the first time in paperback, Richard Crockatt's acclaimed book is an examination of this relationship in its global context. It breaks new ground in seeking a synthesis of historical narrative and analysis of the global structures within which superpower relations developed. Attention is given to economic as well as political and military factors.
