Triumphant science and technology are only at the threshold of man's command over sources of energy so stupendous that, if used for military purposes, they can wipe out our entire civilization.

There is no greater responsibility resting upon peoples and governments everywhere than to make sure that enduring peace will this time - at long last - be established and maintained.

Please let me assure you, however, that the keen disappointment and regret which I feel in this regard serve only to enhance my profound appreciation of the great honor which you have done me; and my sincere gratitude for your generous action.

Under the ominous shadow which the second World War and its attendant circumstances have cast on the world, peace has become as essential to civilized existence as the air we breathe is to life itself.

Fortunately, the war has brought with it not alone a stark realization of what another war would mean to the world, but as well the creation of an international agency through which the nations of the world can, if they so desire, make peace a living reality.

That war has brought with it a truly incredible development of means of destruction and a terrifying prospect of rapid and almost limitless development in that direction.

To be sure, no piece of social machinery, however well constructed, can be effective unless there is back of it a will and a determination to make it work.
