They are moving it back to it's original name [1] likely signalling a move to a world war footing.

The War Department existed for 158 years, from August 7, 1789, to September 18, 1947,[1] when it split into the Department of the Army and the Department of the Air Force under the National Security Act of 1947, joining the Department of the Navy to form the National Military Establishment (NME). In 1949, the NME was renamed the Department of Defense (DOD).

As a 2 flag triangle family household, this is disrespectful and agro.

To be consistent, they might as well rename the Department of Homeland Security "The Ministry of Information Retrieval".
