President Donald Trump on Friday signed an executive order renaming the Department of Defense the "Department of War," a move that administration officials and supporters hailed as a return to historical candor while critics warned it risks glorifying conflict and unsettling allies amid ongoing U.S. military operations.

The order directs Pentagon chief Pete Hegseth, who took the new title of secretary of war, to propose both legislative and executive measures to enshrine the name change, though administration officials acknowledged questions remain about whether the change can be made permanent without congressional approval. The order also allows the department to continue using "Department of Defense" as a secondary name, a concession meant to ease the logistical and symbolic transition across seals, emblems and bureaucratic references.

Supporters said the change restores what they described as an honest label for an institution whose forces have spent decades engaged in combat operations overseas. Secretary of War Hegseth said in an interview that the move was intended as a cultural reset. "Words matter. Titles matter, cultures matter," he told Fox News Digital, adding that the War Department dated to the nation's founding under George Washington.

Jennifer Kavanaugh, a senior fellow at Defense Priorities, said recent U.S. strikes — including attacks on Iranian targets earlier this summer and a strike on a Venezuelan drug-smuggling vessel — have emboldened the administration to lean more heavily on military means. "These two strikes, as well as other small things, are maybe pushing Trump to be more aggressive than he was on the campaign trail," she said. Kavanaugh added that restoring the "War" name may underscore the military's lethality and prompt debate about the armed forces' traditional role in intervening abroad.

Critics argued the renaming is largely symbolic and diverts attention from more pressing strategic decisions, including an impending National Defense Strategy that Pentagon officials plan to release soon. Frank Rose, a former Defense Department and Nuclear Security Administration official, said the title change does not address capability shortfalls. "I have no problem with the [new] name," Rose said. "The real question is this: Will this name change allow us to get capability faster to the warfighter and stay ahead of Russia and China? I’m skeptical. Names don’t deter. Capabilities deter."

John Byrnes, strategic director for Concerned Veterans for America, expressed frustration that the renaming debate could overshadow the forthcoming strategy document, which news reports suggest will pivot resources toward homeland defense and the Western Hemisphere. "This story is overshadowing more important news," Byrnes said.

The renaming revives terminology not used in Washington since the mid-20th century. The original Department of War, established in 1789, oversaw the Army and coastal defenses; the Navy was a separate department. After World War II, the 1947 National Security Act reorganized the nation's military apparatus and in 1949 the National Military Establishment was renamed the Department of Defense to emphasize deterrence and collective security during the Cold War. For more than seven decades, that title has framed U.S. military policy as oriented toward defense and stability rather than overt war-making. Restoring the older name places the United States at odds with the international trend of adopting language that frames armed forces as protectors rather than aggressors.

Some lawmakers quickly criticized the decision. "Totally something my 8-year-old would come up with," Sen. Andy Kim, D-N.J., wrote on X. "Americans want to prevent wars, not tout them." Sen. Mark Kelly, D-Ariz., added on the platform that "Only someone who avoided the draft would want to rename the Department of Defense to the Department of War."

Legal and practical hurdles remain. The executive order instructs the secretary to prepare proposals for both legislative and administrative steps to cement the change, but legal scholars and former officials say a permanent renaming likely requires congressional action because the department's statutory name is set in federal law. The administration's allowance of the old name as a secondary label may blunt some immediate costs and operational disruptions while the question of statutory authority is sorted out.

Analysts noted potential diplomatic and informational consequences. Critics warned that adopting the "Department of War" label could provide adversaries with new propaganda opportunities and unsettle allies who have long framed the U.S. role in security partnerships around deterrence and collective defense. Supporters countered that the label simply reflects long-standing reality about how U.S. military power is used and could strengthen deterrence by signaling willingness to use force.

The renaming comes as U.S. forces continue to carry out targeted strikes abroad and as the administration prepares to publish a new National Defense Strategy, a document produced once per administration that sets priorities and resource allocations. Politico and other outlets have reported that the upcoming strategy will emphasize homeland defense and the Western Hemisphere, a shift that Pentagon officials say reflects evolving threat assessments.

Administration officials framed the executive order as both a historical restoration and a statement of intent about military readiness. Opponents said the change risks elevating rhetoric over substantive investments in modernization, force posture and alliances. With the Department allowed to use its previous name in parallel and with Congress signaling resistance, the practical and legal contours of the renaming effort are likely to be debated in the days and weeks ahead.

Department of Defense seal

The administration has said the department will continue essential operations while the secretary prepares the legislative and regulatory packages called for in the order. The National Defense Strategy, the timeline for congressional review and reactions from U.S. allies are expected to shape whether the "Department of War" becomes a lasting change or a temporary rebranding pending further legal and political negotiation.
