"We have a system which, though far from perfect, is strong with idealism. It gives elbow room for men of all races and all beliefs. It is vital and dynamic. And it works. We have the means of shaping the world in our pattern. If we do, freedom will be assured for all men. The decision is in the hands of this generation. It is a challenge to our political competence. For Western civilization it is the greatest challenge of all time."
