‎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.

That the existence of the Soviet Union has an international revolutionary significance is a commonplace equally recognized by friends and foes.

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.

No one revolution up to now has brought all that was expected of it by the masses. Hence the inevitability of a certain disillusionment, of a lowering of the activity of the vanguard, and consequently, of the growing importance of the rearguard. [Joseph] Stalin's faction has raised itself on the wave of reaction against the October revolution.

The Left Opposition declared that the new tempo of industrialization were above our forces, and that the liquidation of the kulaks as a class in the course of three years was a fantastic task, if one wishes to say so, we find ourselves this time "less radical" than the Stalinists.

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

Fascism is nothing but capitalist reaction...
