“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.”

“Because totalitarian rule strives for the impossible and wants to place at its disposal the personality of man and destiny, it can be realized only in a fragmentary manner. It lies in its being that its goal can never be attained and made total but must remain a tendency, a claim to rule. . . . Totalitarian rule is not a thoroughly rationalized apparatus, that works with equal effectiveness in all its parts. This is something it would well like to be and in some places it may perhaps approach this ideal, but seen as a whole, its claim to power is realizable only in a diffuse manner, with very different intensities at various times in various realms of life; at the same time, totalitarian and non-totalitarian features are always commingled. But this is precisely why the consequences of the totalitarian claim to power are so dangerous and oppressive, because they are so hazy, so incalculable, and so difficult to demonstrate. . . . This contortion follows from the unfulfillable aspiration to power: it characterizes life under such a regime and makes it so exceedingly difficult for all outsiders to grasp.”
