“Judged in terms of its own aspirations, the Communist regime was a monumental failure; it succeeded in one thing only - staying in power. But since for Bolsheviks power was not an end in itself but means to en end, its mere retention does not qualify the experiment as a success. The Bolsheviks made no secret of their aims: toppling everywhere regimes based on private property and replacing them with a worldwide union of socialist societies. They succeeded nowhere outside the boundaries of what had been the Russian Empire in spreading their regime until the end of World War II, when the Red Army stepped into the vacuum created in Eastern Europe by the surrender of Germany, the Chinese Communists seized control of their country from the Japanese, and Communist dictatorships, aided by Moscow, established themselves in a number of recently emancipated colonial areas.”
