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.
Leon TrotskyThe 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.
Leon TrotskyA means can be justified only by its end. But the end in its turn needs to be justified.
