The completion of the socialist revolution within national limits is unthinkable. - Leon Trotsky

The permanent revolution, in the sense which Marx attached to this concept, means a revolution which makes no compromise with any single form of class rule, which does not stop at the democratic stage, which goes over to Socialist measures and to war against reaction from without; that is, a revolution whose every successive stage is rooted in the preceding one and which can end only in the complete liquidation of class society.

The [Soviet Union] bureaucracy not only has not disappeared, yielding its place to the masses, but has turned into an uncontrolled force dominating the masses.

The principles of liberalism can have a real existence only in conjunction with a police system. Anarchism is an attempt to cleanse liberalism of the police. But just as pure oxygen is impossible to breathe, so liberalism without the police principle means the death of society. Being a shadow-caricature of liberalism, anarchism as a whole has shared its fate. Having killed liberalism, the development of class contradictions has also killed anarchism. Like every sect which founds its teaching not upon the actual development of human society, but upon the reduction to absurdity of one of its features, anarchism explodes like a soap bubble at that moment when the social contradictions arrive at the point of war or revolution.
