If it were necessary to give the briefest possible definition of imperialism, we should have to say that imperialism is the monopoly stage of capitalism.
Freedom in capitalist society always remains about the same as it was in ancient Greek republics: Freedom for slave owners.
When there is state there can be no freedom, but when there is freedom there will be no state.

Can a nation be free if it oppresses other nations? It cannot.
Without revolutionary theory there can be no revolutionary movement.
