The renaming of the Defense Department should have surprised no one. The recent rechristening of the Department of Defense as the Department of War was certainly a culture-war stunt like Trump’s demand that the Gulf of Mexico be renamed the Gulf of America. The Department of Defense has always been the Department of War. It was in such a climate that American officials moved to abandon the title of the Department of War in 1947, rebranding it as the Department of Defense two years later. The reversion of the Defense Department to the War Department should be seen less as a rupture than a revelation.
