"In order to bring a nation to support the burdens of 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. 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 sacrifice. Once these exist, we have gone a long way on the path to war."
