“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.”

John Foster Dulles
