...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.

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.

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.

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

...a great army of the proletarian party [must be] prepared to smash the reactionary forces and to clear the way for the advanced forces of society.

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