“I have, therefore, chosen this time and place to discuss a topic on which ignorance too often abounds and the truth too rarely perceived. And that is the most important topic on earth: peace. What kind of peace do I mean and what kind of a peace do we seek? Not a Pax Americana enforced on the world by American weapons of war. Not the peace of the grave or the security of the slave. I am talking about genuine peace, the kind of peace that makes life on earth worth living, and the kind that enables men and nations to grow, and to hope, and build a better life for their children -- not merely peace for Americans but peace for all men and women, not merely peace in our time but peace in all time.
“I speak of peace because of the new face of war. Total war makes no sense in an age where great powers can maintain large and relatively invulnerable nuclear forces and refuse to surrender without resort to those forces. It makes no sense in an age where a single nuclear weapon contains almost ten times the explosive force delivered by all the allied air forces in the Second World War. It makes no sense in an age when the deadly poisons produced by a nuclear exchange would be carried by wind and water and soil and seed to the far corners of the globe and to generations yet unborn.
“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.” ~ John F. Kennedy
