“The proletariat thus shared its dictatorship with nobody. As to the question of the "majority", this never troubled Lenin much. In an article "Constitutional Illusions" (Aug. 1917; Works, vol. 25, p. 201) he wrote: "in time of revolution it is not enough to ascertain the ‘ will of the majority’ – you must prove to be stronger at the decisive moment and at the decisive place; you must win … We have seen innumerable examples of the better organized, more politically conscious and better armed minority forcing its will upon the majority and defeating it." (pg. 503) Trotsky, however, answers questions [in The Defence of Terrorism] that Lenin evaded or ignored. "Where is your guarantee, certain wise men ask us, that it is just your party that expresses the interests of historical development? Destroying or driving underground the other parties, you have thereby prevented their political competition with you, and consequently you have deprived yourselves of the possibility of testing your line of action." Trotsky replies: "This idea is dictated by a purely liberal conception of the course of the revolution. In a period in which all antagonisms assume an open character; and the political struggle swiftly passes into a civil war, the ruling party has sufficient material standard by which to test its line of action, without the possible circulation of Menshevik papers. Noske crushes the Communists, but they grow. We have suppressed the Mensheviks and the S. R. s [Socialist Republics] … and they have disappeared. This criterion is sufficient for us" (p. 101). This is one of the most enlightening theoretical formulations of Bolshevism, from which it appears that the "rightness" of a historical movement or a state is to be judged by whether its use of violence is successful. Noske did not succeed in crushing the German Communists, but Hitler did; it would thus follow from Trotsky’ s rule that Hitler "expressed the interests of historical development". Stalin liquidated the Trotskyists in Russia, and they disappeared – so evidently Stalin, and not Trotsky, stood for historical progress.”
