We know now that the basic proposition of the worth and dignity of man is not a sentimental aspiration or a vain hope or a piece of rhetoric. It is the strongest, most creative force now present in this world.
Now let us use that force and all our resources and all our skills in the great cause of a just and lasting peace!
The Three Great Powers are now more closely than ever bound together in determination to achieve that kind of peace. From Teheran, and the Crimea, from San Francisco and Berlin — we shall continue to march together to a lasting peace and a happy world!
