Peace is never long preserved by weight of metal or by an armament race. Peace can be made tranquil and secure only by understanding and agreement fortified by sanctions. We must embrace international cooperation or international disintegration. Science has taught us how to put the atom to work. But to make it work for good instead of for evil lies in the domain dealing with the principles of human dignity. We are now facing a problem more of ethics than of physics.
Bernard Baruch
