Pentagon says the last US troops have left Iraq, formally ending the 12-year anti-ISIS mission
The Pentagon keeps only training and intelligence support and says "ISIS remnants and Iran-aligned militias" are now Baghdad's job.
- Aug. 31 — Military leaders warned Defense Secretary Pete Hegseth a long Iran war would leave US forces exposed elsewhere; the Pentagon called the leak a crime. - Sept. 14–16 — The Pentagon put defense makers on wartime footing; its watchdog priced the war at $33.4 billion through June 30, plus $3.7 billion in lost equipment. - Sept. 29 — US officials said an Iranian cruise missile hit a ship carrying eight Marines in the Strait of Hormuz on Sept. 14; the Pentagon never announced it. - Sept. 30 — US forces began their final exit from Iraqi bases, a move Reuters and the Washington Post judged shifts power toward Iran, its militias and ISIS.
ContextThis is only the second time all US forces have left Iraq. The first exit was complete by Dec. 18, 2011, and US advisers were back against ISIS in June 2014, 30 months later. When the coalition ended its combat mission on Dec. 9, 2021, about 2,500 US troops stayed on as trainers and advisers. A September 2024 US-Iraq joint statement let the coalition keep fighting ISIS from Iraq "at least through 2026"; its first phase closed coalition sites outside Kurdistan by September 2025. About 4,500 US troops have died in Iraq since 2003, most of them before 2011.
