This book, first published in 1989, is a comprehensive examination of the profound impact of World War II on Soviet military affairs. It systematically assesses the costs and lessons of the war and their substantial impact on Soviet military and Party leaders in the Cold War era and particularly in the 1980s. Starting with the experiences of the war and its influence on the development of Soviet military thinking, the book addresses the relationship between the military and the Soviet political system, threat perception, decision making, and crisis and risk assessment. Also discussed are the war’s influence on the structure and operations of the military in the 1980s, focusing on doctrine, conventional forces, the defence industry and historiography.
