Trump Signs Order Renaming Defense Department to War Department

US President Donald Trump has signed an executive order renaming the Department of Defense to the Department of War, marking a return to the name used for 158 years until 1947. The announcement was made today, September 5, 2025, during a press briefing at the White House.

The decision to revert to the historical name aims to emphasize a more aggressive military posture, according to sources close to the administration. Trump stated that the change reflects a commitment to national security and a more transparent approach to military engagements.

The Department of War was originally established in 1789, overseeing military operations until it was restructured into the Department of Defense after World War II. This name change has sparked debate among lawmakers and military analysts, with some arguing it could alter public perception of military actions and increase support for military initiatives.

Critics have raised concerns about the implications of this decision, fearing it might lead to escalated military action abroad. As the administration moves forward with this rebranding, it remains to be seen how this will influence military policy and international relations.
