Lightly armed nations can move toward war just as easily as those which are armed to the teeth, and they will do so if the usual causes of war are not removed.
When distrust exists between governments, when there is a danger of war, they will not be willing to disarm even when logic indicates that disarmament would not affect military security at all.
Armaments are necessary - or are maintained on the pretext of necessity - because of a real or an imagined danger of war.
Let us assume that the ideal were reached; let us imagine a state of international life in which the danger of war no longer exists. Then no one would dare to demand a penny for obviously completely superfluous armaments.
