"Human beings have got a lot of good, noble impulses inside them, and most people want to be good and do more good than they do evil. Hell, we've had nuclear weapons now for thirty or thirty-five years and nothing's happened yet. That in itself seems to be a miracle. If Reagan pushes the button or somebody pushes the button in Russia or somebody pushes it in Costa Rica, they can put a big tombstone in outer space that says, "We gave it a good try." Because we have."
