I thought the executive had the power to rename existing departments and map landmarks. That's why we got "DOGE" disgused under the USDS and the "Gulf of America".
If that's not legal, I'll do my best to act shocked.
In this case, the executive had the power to add a secondary title, Department of War. It does not override the primary name of Dept of Defense but it appears to be the proper amount of appeasement.
> Within 60 days of the date of this order, the Secretary of War shall submit to the President (...) a recommendation on the actions required to permanently change the name of the Department of Defense to the Department of War. This recommendation shall include the proposed legislative and executive actions necessary to accomplish this renaming.
It may currently be a second name, but the explicit intention is for it to become the only one. In HN terms I'd argue that saying "there is no Department of War" is akin to arguing that a piece of software doesn't have feature X because it's only available in the beta release.
AKA - it’s the department of defense in the same way Robert Kennedy was named Robert but went by Bobby sometimes. Trump doesn’t get to change the name, just assign an unofficial nickname that he thinks sounds more tough. Sort of like his pretend tough guy Secretary of defense that dresses up as a Secretary of war for TV moments. The fact they drag along the entire military and its leadership in their charade is embarrassing, and the asinine nickname is expensive and likely causes operational confusion.
