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

It is difficult for me to imagine what "personal liberty" is enjoyed by an unemployed person, who goes about hungry, and cannot find employment.

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

History shows that when any state intends to make war against another state, even not adjacent, it begins to seek for frontiers across which it can reach the frontiers of the state it wants to attack. Usually, the aggressive state finds such frontiers.

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.

...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.
