"Many forces have converged to make the modern world. Atomic power is very high among those forces, but what has the atomic age meant for those of us who have come here to this dinner tonight? It means, I think, that we have a unique responsibility, unique in history, for the defense of freedom. Our nuclear power alone has deterred Soviet aggression. Under the shadow of our strength, our friends have kept their freedom and have built their nations. It means that we can no longer wait for the tides of conflict to touch our shores. It means that great powers can never again delude themselves into thinking that war will be painless or that victory will be easy. Thus, atomic power creates urgent pressure for peaceful settlements, and for the strengthening of the United Nations. It means a change must come in the life of nations. Man has fought since time began, and now it has become clear that the consequences of conflict are greater than any gain, and man just simply must change if man is to survive. For Americans, it means that control over nuclear weapons must be centralized in the hands of the highest and the most responsible officer of government--the President of the United States. He, alone, has been chosen by all the people to lead all the Nation. He, alone, is the constitutional Commander in Chief of the Nation. On his prudence and wisdom alone can rest the decision which can alter or destroy the Nation."
