So in your discussions of the nuclear freeze proposals, I urge you to beware the temptation of pride -- the temptation blithely to declare yourselves above it all and label both sides equally at fault, to ignore the facts of history and the aggressive impulses of an evil empire, to simply call the arms race a giant misunderstanding and thereby remove yourself from the struggle between right and wrong, good and evil.
History teaches that wars begin when governments believe the price of aggression is cheap. To keep the peace, we and our allies must be strong enough to convince any potential aggressor that war could bring no benefit, only disaster.

Above all, we must realize that no arsenal, or no weapon in the arsenals of the world, is so formidable as the will and moral courage of free men and women. It is a weapon our adversaries in today's world do not have.
