Bertrand Russell,
Why Men Fight: A method of abolishing the international duel
“ Fear of the danger within is enhanced by fear of the danger without. Every State is exposed at all times to the risk of foreign invasion. No means has hitherto been devised for minimizing this risk except the increase of armaments. But the armaments which are nominally intended to repel invasion may also be used to invade. And so the means adopted to diminish the external fear have the effect of increasing it, and of enormously enhancing the destructiveness of war when it does break out. ”
