Not believing in force is the same as not believing in gravity.

A program of "disarmament," while imperialist antagonisms survive, is the most pernicious of fictions. Even if it were realized by way of general agreement - an obviously fantastic assumption!- that would by no means prevent a new war. The imperialists do not make war because there are armaments; on the contrary, they forge arms when they need to fight.
