War is often used as a last ditch effort to prevent deteriorating economic conditions or currency crises, particularly by expanding services and employment in the military, and by simultaneously depopulating segments of the population to free up resources and restore the economic and social order. A temporary war economy can also be seen as a means to avoid the need for more permanent militarization. During World War II, United States President Franklin D. Roosevelt stated that if the Axis powers won, then "we would have to convert ourselves permanently into a militaristic power on the basis of war economy."
