We must bear in mind that the growth of the power of the Soviet state will increase the resistance of the last remnants of the dying classes. It is precisely because they are dying, and living their last days that they will pass from one form of attack to another, to sharper forms of attack, appealing to the backward strata of the population, and mobilizing them against the Soviet power. There is no foul lie or slander that these ‘have-beens’ would not use against the Soviet power and around which they would not try to mobilize the backward elements. This may give ground for the revival of the activities of the defeated groups of the old counter-revolutionary parties: the Socialist-Revolutionaries, the Mensheviks, the bourgeois nationalists in the centre and in the outlying regions; it may give grounds also for the revival of the activities of the fragments of counter-revolutionary opposition elements from among the Trotskyites and the Right deviationists. Of course, there is nothing terrible in this. But we must bear all this in mind if we want to put an end to these elements quickly and without great loss.
– Josef Stalin, explaining in The Results of the First Five-Year Plan (1933), that criticism of the Dictatorship of the Proletariat could only come from those who were hopeless suckers for capitalism, not because the Soviet Union was a totalitarian state.
