With a blinding flash the world entered the nuclear age in 1945, bringing to an end the greatest calamity in human history. In the aftermath of Hiroshima and Nagasaki, the speculation grew (and continues today) that the A-bombs had been used?at least in part?to demonstrate American strength and resolution to the Soviet Union. The devil?s bargain of alliance with Stalin had rapidly degenerated as Nazi defenses collapsed. The seeds of the Cold War were sown well before VE-Day.
The postwar division of Europe was inevitable given the fact of Soviet military occupation. Unless the U.S. (and other Allies) went to war with the U.S.S.R. to liberate eastern Europe, Soviet control was a fait accompli. Postwar tensions (e.g. the communist revolution in Greece) quickly led to the development of the Truman Doctrine?the U.S. would seek to ?contain? the expansion of the Soviet empire by all means short of total war.
In Europe, the Iron Curtain (in Churchill?s eloquent description) would be the trip line for total war?hostilities between the U.S. and U.S.S.R. would rapidly escalate beyond diplomacy unless cool heads prevailed. When the Berlin crisis occurred in 1948, the U.S. monopoly on nuclear weapons undoubtedly deterred further Soviet aggression. Within a year, the monopoly ended and the nuclear arms race began. The arsenal of megadeath still stands poised for World War III.
Should (could) the western allies have freed eastern Europe from communism in 1945? Was Cold War a better choice (more cost effective, less deadly, etc.)?
