America's leadership and prestige depend, not merely upon our unmatched material progress, riches and military strength, but on how we use our power in the interests of world peace and human betterment.

... The future is very markedly in your hands, its value and its moral standing in the world and among ourselves. If you will take the power you have and use it, I have no fear of the outcome of the future.

Against the dark background of the atomic bomb, the United States does not wish merely to present strength, but also the desire and the hope for peace.

I call upon those who love freedom to stand with us now. Together we shall achieve victory.

The free world must not prove itself worthy of its own past.

. . .a sense of humor can be a great help-particularly a sense of humor about (oneself). William Howard Taft joked about his own corpulence and people loved it; took nothing from his inherent dignity. Lincoln eased tense moments with bawdy stories, and often poked fun at himself-and history honors him for this human quality. A sense of humor is part of the art of leadership, of getting along with people, of getting things done.

The United States pledges before you-and therefore before the world-its determination to help solve the fearful atomic dilemma-to devote its entire heart and mind to find the way by which the miraculous inventiveness of man shall not be dedicated to his death, but consecrated to his life.
