"The Nation As Person metaphor is pervasive, powerful, and part of an elaborate metaphor system. It is part of an International Community metaphor, in which there are friendly nations, hostile nations, rogue states, and so on. This metaphor comes with a notion of the national interest: Just as it is in the interest of a person to be healthy and strong, so it is in the interest of a Nation-Person to be economically healthy and militarily strong. That is what is meant by the "national interest."

In the International Community, peopled by Nation-Persons, there are Nation-adults and Nation-children, with Maturity metaphorically understood as Industrialization. The children are the "developing" nations of the Third World, in the process of industrializing, who need to be taught how to develop properly and to be disciplined (say, by the International Monetary Fund) when they fail to follow instructions. "Backward" nations are those that are "underdeveloped." Iraq, despite being the cradle of civilization, is seen via this metaphor as a kind of defiant armed teenage hoodlum who refuses to abide by the rules and must be "taught a lesson."
