War as metaphor

The use of war as metaphor is a longstanding literary and rhetorical trope. In political usage, war metaphors are used to manage a perceived societal problem, with the concept taking the place of an individual or state enemy in true war. The war metaphor is sometimes invoked to pursue ordinary domestic politics.

Philosopher James Childress describes the use of war as a metaphor as a dilemma: "In debating social policy through the language of war, we often forget the moral reality of war." One fundamental problem is that it is often unclear when the "war" is over. Simon Jenkins, Fellow of the Royal Society of Literature, said that "Never, ever, should a government use war as a metaphor in a time of peace."
