This book provides important new evidence to support the thesis that the primary reason for bombing Hiroshima and Nagasaki was not to end the war in Japan, as was said at the time, but to 'make the Russians more manageable'.Drawing on recently released diaries and records of Truman, Eisenhower and others, Alperovitz re-evaluates the assumptions, hesitations and decisions that precipitated the use of atomic weapons and traces how possession of the bomb changed American strategy toward the Soviet Union at the Potsdam Conference and helped to set it on a course that contributed to the swift beginning of the Cold War.Most historians of the period now agree that diplomatic considerations related to the Soviet Union played a major role in the decision to use the bomb. Atomic Diplomacy pioneered this new understanding. Today we still live in Hiroshima's shadow; this path breaking work is timely and urgent reading for anyone interested in the history - and future - of peace and war.
