In the appendix to my History of the Russian Revolution I give a detailed and documented study of the ideas of the Bolshevik party on the October revolution. This study, I hope, will make it impossible in the future to ascribe to [Vladimir] Lenin the theory of Socialism in a single country.
Leon TrotskySocialist economy cannot reject the huge advantages of the world division of labor: on the contrary, it will carry it to the highest development. But in practise, it is not a question of the future socialist society, with an established internal equilibrium, but of the given technically and culturally backward country which in the interests of industrialisation and collectivization is forced to export as much as possible in order to import as much as possible.
Leon TrotskyAll the parties of capitalist society, all its moralists and all its sycophants will perish beneath the debris of the impending catastrophe. The only party that will survive is the party of the world socialist revolution.
Leon TrotskyIt is therefore not true that the mere existence of the Soviet Union is capable of assuring the victory of the revolution in other countries.
Leon TrotskyCan and must! The proclamation of this new conception of [Joseph Stalin] is closed by the same words, "Such are in general the characteristic features of Lenin's conception of the proletarian revolution." In the course of a single year Stalin ascribed to [Vladimir] Lenin two directly opposed conceptions of the fundamental question of socialism. The first version represents the real tradition of the party; the second took shape in Stalin's mind only after the death of Lenin, in the course of the struggle against "Trotskyism".
