The United States underwent an unprecedented mobilization of national resources for the Second World War. Conditions in the United States were not as strained as they were in the United Kingdom or as desperate as they were in the Soviet Union, but the United States greatly curtailed nearly all non-essential activities in its prosecution of the Second World War and redirected nearly all available national resources to the conflict, including reaching the point of diminishing returns by late 1944, where the U.S. military was unable to find any more males of the correct military age to draft into service.
