Although both Truman and Stalin helped increase tensions in Europe and East Asia in the years immediately following World War II, the Cold War itself was likely inevitable. The alliance that had formed between the United States and the USSR during World War II was not strong enough to overcome the past decades of suspicion and unease between the two nations. Moreover, as both leaders sought to achieve their postwar security objectives, which were often mutually exclusive, neither was willing to compromise.

Americans had hated and feared Communism ever since it had appeared in the Bolshevik Revolution of 1917 and had refused to recognize the new Soviet government, especially after Bolshevik leaders promoted the destruction of capitalism. During World War II, Roosevelt and British prime minister Winston Churchill delayed their decision to open a second front, which would have distracted the Nazis and taken pressure off the Red Army entrenched at Stalingrad. Stalin resented this delay, just as he resented the fact that the United States and Great Britain refused to share their nuclear weapons research with the Soviet Union.

Whereas other major world powers such as Great Britain, France, Italy, and Germany lay in ruins, the Soviet Union and the United States still had manufacturing and military capabilities. The world had been a multipolar one before the war but was bipolar afterward, and this
