The pillars of Hercules of the United States are vulgarity and stupidity.

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

Only when the kulak refused to deliver grain to the State did [Joseph] Stalin, under the pressure of the Left Opposition, accomplish a sharp turn. Being the empiricist that he is, he moved, to the opposite extreme, and set as a task for two or three years the collectivization of all the peasantry, the liquidation of the kulaks as a class, and the compression of the Five Year Plan into four years.

In spite of the existence of the Soviet Union, however, the proletarian revolution during the past years has not recorded a victory in any other country.

History has different yardsticks for the cruelty of the Northerners and the cruelty of the Southerners in the Civil War. A slave-owner who through cunning and violence shackles a slave in chains, and a slave who through cunning or violence breaks the chains – let not the contemptible eunuchs tell us that they are equals before a court of morality!

The clearer and deeper the public opinion of the world, in the first instance the opinion of the working masses, will understand the contradictions and the difficulties of the socialist development of an isolated country, the higher will it appreciate the results achieved. The less it identifies the fundamental methods of Socialism with the zigzags and errors of the Soviet bureaucracy, the less will be the danger that, by the inevitable revelation of these errors and of their consequences, the authority, not only of the present ruling group, but of the workers' State itself, may decline.

It is also false that the revolution ripens and comes to development only in the national soil.
