In 1917 there was not a single Bolshevik who considered possible the realization of a socialist society in a single country, and least of all in Russia.

Our differences with [Joseph] Stalin are entirely of a strategical character.

All 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.

The slanders poured down like Niagara. If you take into consideration the setting - the war and the revolution - and the character of the accused - revolutionary leaders of millions who were conducting their party to the sovereign power - you can say without exaggeration that July 1917 was the month of the most gigantic slander in world history.

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.

Technique is noticed most markedly in the case of those who have not mastered it.

If we close our eyes to the dark sides of the workers' State which we have helped to create, we shall never reach socialism.
