Vladimir Lenin Quote
Peaceful surrender of power by the bourgeoisie is possible, if it is convinced that resistance is hopeless and if it prefers to save its skin. It is much more likely, of course, that even in small states socialism will not be achieved without civil war, and for that reason the only programme of international Social-Democracy must be recognition of civil war, though violence is, of course, alien to our ideals.
