In a dramatic shift of tone, President Donald Trump signed an executive order on Friday (September 5, 2025), rebranding the U.S. Department of Defence as the “Department of War”.
The move, projected as a reassertion of U.S. military dominance, comes at a time when Mr. Trump has spent months campaigning for the Nobel Peace Prize.
The order authorises Defence Secretary Pete Hegseth to use the secondary title “Secretary of War” in official correspondence and public communications, according to a White House fact sheet.
The Pentagon’s website was changed from defense.gov to war.gov, and signs around Mr. Hegseth’s office were replaced. On social media, the Pentagon’s X account rebranded as the “Department of War”, complete with a new seal for its profile picture and banner image. Mr. Trump also announced that new stationery would soon be in circulation.
Costly rebranding and its legal flaws
The Department of War was created in 1789, then renamed and reorganised through legislation signed by President Harry Truman in 1947, two years after the end of World War II. The Congress debated for two years before passing the 1947 National Security Act. The sweeping law created a single Pentagon department called “The National Military Establishment”. It also created the National Security Council to advise the President and established the Central Intelligence Agency. The new name – NME – unintentionally read as “Enemy,” prompted the Congress in 1949 to rename it as the “Department of Defence.”
Even though Mr. Trump has rebranded the Department of Defence to the Department of War through an executive order, the move is riddled with legal flaws.
According to a White House fact sheet, the rebranding permits the use of “Department of War” as a secondary title in official communications. That includes revised email footers, signage, and social media branding.

Even using the new title in a secondary capacity comes with a significant price tag. Updating signs, branding, and letterheads — both at the Pentagon and across military installations worldwide — could cost tens of millions of dollars. That figure runs contrary to Mr. Trump’s administration’s long-touted efforts to cut government spending.
While the optics are dramatic, the legal foundation of Mr. Trump’s move is far shakier. The National Security Act of 1947, passed by the Congress and signed into a law by President Truman, codified the Department of Defence as the statutory title of the nation’s military establishment. While the executive order can permit internal and non-statutory use of the new title, it cannot legally override the name.
For it to carry legal weight, the Congress has to pass legislation amending the 1949 statute. Until the Congress passes that legislation, the renaming remains unofficial in legal terms. Mr. Trump is expected to submit the change to the Congress for approval in the coming weeks.
What Trump hopes to achieve

Mr. Trump said the change was intended to signal to the world that the United States remains a force to be reckoned with. He also criticised the current name — Department of Defence — as “woke”. “I think it sends a message of victory. I think it sends, really, a message of strength,” Mr. Trump said, as he authorised the use of “Department of War” as a secondary title for the Pentagon.
The decision comes with Mr. Trump’s broader second-term ambitions: to centralise power and project toughness thereby rallying his political base while reframing America’s military posture in global space.
Throughout his presidency, Mr. Trump has leaned heavily on the military to support his policy agenda — including immigration enforcement and domestic law-and-order initiatives. He has deployed the National Guard in Washington, D.C., and has signalled an intention to expand military involvement to other Democratic-led cities like Chicago and New York. He has also ordered military strikes in the Caribbean, targeting what the administration calls “Venezuelan cartel boats,” and authorised a controversial bombing of Iranian nuclear sites in June.
The rebranding, he said, sends a “message of victory” to the rest of the world.
The latest rebranding forms part of Mr. Trump’s wider push to project strength both at home and abroad during his second term, aligning with his revived “Make America Great Again” policy.
Mr. Trump had earlier complained that the current department name was overly “defensive”. “I don’t want to be defence only. I want defence, but I want offence too,” he said.
Still, the path ahead is uncertain. Until the Congress enshrines the name change into law, the “Department of War” exists only in rhetoric, not reality. And with legal and logistical roadblocks mounting, it remains to be seen whether the new label will be more than a political flourish.
