Mankind will never win lasting peace so long as men use their full resources only in tasks of war. While we are yet at peace, let us mobilize the potentialities, particularly the moral and spiritual potentialities, which we usually reserve for war.

In order to bring a nation to support the burdens incident to maintaining great military establishments, it is necessary to create an emotional state akin to war psychology. There must be the portrayal of an external menace or of internal conditions rendered intolerable by the unjust restraints of foreign nations. This involves the development to a high degree of the nation-hero nation-villain ideology and the arousing of the population to a sense of the duty of sacrifice.

Peace will never be won if men reserve for war their greatest efforts, Peace, too, requires well-directed and sustained sacrificial endeavor. Given that, we can, I believe, achieve the great goal of our foreign policy, that of enabling our people to enjoy in peace the blessings of liberty.

The U.S. has no friends, only interests.
