National self-sufficiency or "autarchy" is the ideal of [Adolf] Hitler, not of [Karl] Marx and [Vladimir] Lenin.

The Soviet Union needs thinking and critical friends, such as are capable not only of singing hymns in the hours of success, but of not shrinking in the hour of defeat and danger.

In Stalin each [Soviet bureaucrat] easily finds himself. But Stalin also finds in each one a small part of his own spirit. Stalin is the personification of the bureaucracy. That is the substance of his political personality.

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.

Yet the proletariat has not only a vanguard, but also a rearguard, and besides the proletariat there are the peasantry and the bureaucracy.

It is therefore not true that the mere existence of the Soviet Union is capable of assuring the victory of the revolution in other countries.

‎The party that leans upon the workers but serves the bourgeoisie, in the period of the greatest sharpening of the class struggle, cannot but sense the smells wafted from the waiting grave.
