When I first saw this headline, I thought it was from The Onion or The Bablyon Bee, but apparently it is real.
The article notes the US had a Department of War up until 1947. I always admired the marketing behind that decision: your military seems much more just if it's always acting in defense...
But maybe there was a negative side to it: if you only have a department of defense, you aren't very threatening.
I wonder how much we should read into the fact that the people who fought one of the largest wars our nation has ever been involved in decided to change the name of to the Department of Defense -- while the people who have not fought wars against any serious enemy are now deciding to revert the name to the Department of War.
