The War Department has not existed since the passage of the National Security Act of 1947 and the government department has been known as the Department of Defense under US law since the act was amended in 1949. If you have an issue with it, take it up with Congress.

		Changing a domain name doesn't actually amend federal law. Just like how changing Kennedy Center letterhead to Trump Kennedy Center for a year didn't actually legally rename it. Once a case with sufficient standing got in front of a judge it reverted to the actual legal name on the basis that only Congress can change the statutorily defined name.
