Two years ago I told this body that the United States had proposed, and was willing to sign, a limited test ban treaty. Today that treaty has been si… - John F. Kennedy

One hundred years of delay have passed since President Lincoln freed the slaves, yet their heirs, their grandsons, are not fully free. They are not yet freed from the bonds of injustice. They are not yet freed from social and economic oppression. And this Nation, for all its hopes and all its boasts, will not be fully free until all its citizens are free.

In short, we are neither "warmongers" nor "appeasers," neither "hard" nor "soft." We are Americans, determined to defend the frontiers of freedom, by an honorable peace if peace is possible, but by arms if arms are used against us. And if we are to move forward in that spirit, we shall need all the calm and thoughtful citizens that this great University can produce, all the light they can shed, all the wisdom they can bring to bear. It is customary, both here and around the world, to regard life in the United States as easy. Our advantages are many. But more than any other people on earth, we bear burdens and accept risks unprecedented in their size and their duration, not for ourselves alone but for all who wish to be free.

A war today or tomorrow, if it led to nuclear war, would not be like any war in history. A full-scale nuclear exchange, lasting less than 60 minutes, with the weapons now in existence, could wipe out more than 300 million Americans, Europeans, and Russians, as well as untold numbers elsewhere. And the survivors, as Chairman Khrushchev warned the Communist Chinese, "the survivors would envy the dead." For they would inherit a world so devastated by explosions and poison and fire that today we cannot even conceive of its horrors. So let us try to turn the world away from war. Let us make the most of this opportunity, and every opportunity, to reduce tension, to slow down the perilous nuclear arms race, and to check the world's slide toward final annihilation.
