I emphasized the significance of revolutionary strategy.

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.

Where force is necessary, there it must be applied boldly, decisively and completely.

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

The depth and strength of a human character are defined by its moral reserves. People reveal themselves completely only when they are thrown out of the customary conditions of their life, for only then do they have to fall back on their reserves.

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

The task of the proletariat is to create a still more powerful fatherland with a far greater power of resistance, the Republican United States of Europe, as the foundation of the United States of the World.
