Department of War & Defense
Military policy has become one of the most contested corners of the administration's agenda: a 108-day war with Iran, a record-setting budget, repeated bipartisan pushback in Congress, and a fight over renaming the Pentagon itself.
- A major U.S.-Israel-Iran war erupted and then reached a fragile truce — A June 2025 U.S. strike on Iranian nuclear sites ("Operation Midnight Hammer") was followed by a 108-day war beginning February 28, 2026, ending with a June ceasefire and a 14-point U.S.-Iran memorandum of understanding, even as strikes briefly flared again in June (Wikipedia, Republic World, CNN).
- Congress voted repeatedly, and with growing bipartisan support, to try to end U.S. involvement in the Iran war — After several failed attempts (a 53-47 Senate defeat in March, a 213-214 House defeat in April, and a 212-212 tied House defeat in May), a War Powers Resolution to end U.S. hostilities with Iran passed the House 215-208 on June 3, 2026, and the Senate 50-48 on June 23, 2026, with several Republicans crossing party lines each time (NPR, CNN, Al Jazeera).
- The Pentagon, now in the process of being renamed the Department of War, is operating at record budget levels — Its FY2026 budget hit $961.6 billion, with the administration seeking a topline near $1.5–1.6 trillion for FY2027 once separate Iran war costs and weapons-stockpile spending are included (Breaking Defense, WTOP/AP).
- Congress has moved to make the "Department of War" name official — Trump's September 2025 executive order made it a secondary title; the House and Senate Armed Services Committees added renaming language to their 2026 defense bills, the House Appropriations Committee approved it in a party-line vote, and the full House passed the annual defense policy bill (NDAA) with the renaming provision 216-212 on July 22, 2026, sending it toward final passage (Stars and Stripes, The Hill, WTOP/AP).
- The administration has threatened military action well beyond Venezuela and Iran — Days after the January 2026 Venezuela strikes, Trump threatened a military operation against Colombia over drug trafficking, prompting Colombian President Gustavo Petro to say he would "take up arms"; tensions eased after Trump invited Petro to the White House, but the episode illustrated a wider pattern of threatened force in the hemisphere (Reuters, The Guardian, Reuters).
The January 2026 strikes on Venezuela and the capture of Nicolás Maduro are covered in their own dedicated issue page: Venezuela & the Maduro Strikes.
Where each side stands
Every point below is sourced to a real organization, official, or news report — click through to read it in full context.
Conservative
Administration officials, including Defense Secretary Pete Hegseth, defended the Iran war as removing an existential nuclear threat and argued Democratic critics who invoked the War Powers Resolution were undermining troops and prolonging the conflict (POLITICO, Al Jazeera).
Commentators like Tucker Carlson and some libertarian-leaning Republicans argued the Iran war betrayed the "no more foreign wars" promise of Trump's base, calling it a war fought for Israel's interests rather than direct U.S. security — exposing a real split within the conservative coalition (The New York Times, POLITICO).
Conservatives backed the $961.6 billion FY2026 defense budget (a 13% increase) and the administration's push toward $1.5 trillion for FY2027, arguing a decade of underinvestment in shipbuilding, munitions, and the nuclear deterrent left the U.S. unprepared for great-power competition (U.S. Department of War, Heritage Foundation).
Secretary Hegseth and House Republicans argue the "Department of Defense" name (adopted in 1949) softened the military's mission, and that "Department of War" better signals strength and deterrence to adversaries; nearly every Republican on the relevant committees and the House floor supported the change (Stars and Stripes, POLITICO).
Supporters of the administration's approach toward Colombia and other Western Hemisphere governments argue that credible threats of military action against drug-trafficking networks and hostile regimes are a legitimate extension of the same logic that justified the Venezuela operation (Reuters).
Progressive
Democratic lawmakers, including potential 2028 candidates, condemned the February 2026 strikes as illegal and pushed War Powers Resolution votes to constrain Trump's ability to continue military action against Iran; those efforts eventually succeeded in both chambers by June 2026, a rare bipartisan rebuke of a sitting president's war-making (The New York Times, CNN).
Progressive members of the Congressional Progressive Caucus, including Rep. Ilhan Omar, argue the FY2026 defense appropriations bill enriches contractors and funds "unconstitutional wars" while the Pentagon has failed every audit since 2018 (Congressional Progressive Caucus).
Senate Budget Committee Democrats, led by Sen. Jeff Merkley, have demanded the Pentagon explain why $60 billion of the $150 billion defense reconciliation fund remains fully classified, warning it undermines oversight and accountability (Military.com).
Rep. Adam Smith, the top Democrat on the House Armed Services Committee, called the renaming "one of the dumbest things" the administration has done and "performative nonsense," while critics cite Congressional Budget Office and Pentagon estimates that the change could cost $52–125 million and require roughly 7,600 changes to federal law — money Democrats argue would be better spent given a defense budget already approaching $1.6 trillion (Stars and Stripes, WTOP/AP).
Critics noted that threatening a NATO-adjacent, democratically elected government like Colombia's just days after the Venezuela strikes fit a troubling pattern of using force, or the threat of it, as a default foreign policy tool in the hemisphere (The Guardian, BBC).
Key facts both sides cite
Data and polling that inform the debate — both camps draw on these figures, even when they read them differently.
FY2026 defense budget — The Pentagon's fiscal year 2026 budget totals $961.6 billion (a 13% increase over FY2025), combining $848.3 billion in discretionary funding with $113.3 billion in mandatory reconciliation funds; the administration has since sought a topline approaching $1.6 trillion for FY2027 once Iran war costs are included, according to Rep. Adam Smith (U.S. Department of War, WTOP/AP).
U.S. Iran war disapproval — A March 2026 Pew Research Center survey found 59% of Americans said the decision to use military force against Iran was wrong, including 78% of Democrats and 52% of Republicans, with 62% overall disapproving of Trump's handling of the conflict (Pew Research Center).
Iran War Powers Resolution vote tallies — After several failed attempts in March, April, and May 2026, Congress passed a concurrent resolution urging an end to hostilities with Iran — 215-208 in the House on June 3 and 50-48 in the Senate on June 23 — with GOP Senators Rand Paul, Susan Collins, Lisa Murkowski, and Bill Cassidy and four House Republicans crossing party lines (NPR, Al Jazeera).
Department of War renaming cost and vote history — The Pentagon estimated the rename would cost about $52 million and require roughly 7,600 changes to federal law, while the Congressional Budget Office projected up to $125 million; the House Armed Services Committee approved the provision 44-12 (June 5), the House Appropriations Committee 34-27 (June 25), and the full House passed the NDAA including the renaming language 216-212 on July 22, 2026 (Stars and Stripes, The Hill, WTOP/AP).
