Today the expenditure of billions of dollars every year on weapons acquired for the purpose of making sure we never need them is essential to the keeping of peace. But surely the acquisition of such idle stockpiles -- which can only destroy and never create -- is not the only, much less the most efficient, means of assuring peace. I speak of peace, therefore, as the necessary, rational end of rational men. I realize the pursuit of peace is not as dramatic as the pursuit of war, and frequently the words of the pursuers fall on deaf ears. But we have no more urgent task.
