War may break out unexpectedly. Wars are not declared, nowadays. They simply start.

In socialist society certain inequalities in property still exist. But in socialist society there is no longer unemployment, no exploitation, no oppression of nationalities. In socialist society everyone is obliged to work, although he does not, in return for his labour receive according to his requirements, but according to the quantity and quality of the work he has performed.

Capitalism, in its imperialist phase, is a system which considers war to be a legitimate instrument for settling international disputes, a legal method in fact, if not in law.

It was not Soviet people who formed the American Communist Party.

American democracy and the Soviet system may peacefully exist side by side and compete with each other. But one cannot evolve into the other.

...the transition from capitalism to Socialism and the liberation of the working class from the yoke of capitalism cannot be effected by slow changes, by reforms, but only by a qualitative change of the capitalist system, by revolution. Hence, in order not to err in policy, one must be a revolutionary, not a reformist.

We Marxists believe that a revolution will also take place in other countries. But it will take place only when the revolutionaries in those countries think it possible, or necessary. The export of revolution is nonsense. Every country will make its own revolution if it wants to, and if it does not want to, there will be no revolution.
