“The Cold War in its original form was a presumably mortal antagonism, arising in the wake of the Second World War, between two rigidly hostile blocs, one led by the Soviet Union, the other by the United States.” (Arthur Schlesinger, Jr. – The Russian Revolution-Fifty Years After). During the Second World War, the United States deliberately abandoned the wartime policy of collaboration and, exhilarated by the possession of the atomic bomb, undertook a course of aggression of its own designed to expel all Russian influence from Eastern Europe and to establish democratic-capitalist states on the very border of the Soviet Union. As the revisionists see it, this radically new American policy - or rather this resumption by Truman of the pre-Roosevelt policy of insensate anti-communism - left Moscow no alternative but to take measures in defence of its own borders. The result was the Cold War.
The origins of the Cold War are diverse, and though it is possible to attribute worth to Stalin’s blockading of Berlin, it would be impulsive to state that this was the most decisive factor that began the Cold War. Other factors may be given weight, whether equal or not, to the subsequent political events.
