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. 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."

United States (US)
Early examples of war as metaphor in US political discourse include J. Edgar Hoover's "war on crime" in the 1930s.

Other high-profile examples include the War on Poverty, War on Cancer, War on Drugs, War on Gangs, War on Women, and the War on Christmas.
