U.S. Forces Complete Final Withdrawal from Iraq
By Drooid · · How we work
Core Event
On September 30, 2026, the United States completed the departure of all remaining troops and equipment from Erbil Air Base in Iraq’s Kurdish region, ending a 12-year anti-ISIS campaign known as Operation Inherent Resolve. The pullout fulfills a 2024 agreement linking the coalition’s exit to Baghdad’s plan to bring Iran-backed militias under state control.
Background & Context
U.S. forces first entered Iraq in 2003, peaking at about 170,000 personnel in 2007. After a 2011 withdrawal, a smaller contingent returned in 2014 at Baghdad’s request to combat ISIS, which at its height controlled roughly one-third of Iraq and Syria. By 2017 ISIS lost its territorial “caliphate,” and the coalition shifted to training, advising and intelligence support. The 2024 timetable set a September 30 deadline for the final drawdown, with the Iraqi government initially promising to disarm non-state armed groups by that date.
Data & Statistics
- Troop levels: About 2,500 U.S. personnel remained in Iraq in 2025, concentrated in Erbil.
- ISIS activity: CENTCOM commander Adm. Brad Cooper reported a 70 % drop in ISIS attacks since 2023, the lowest level since 2013. The Defense Intelligence Agency assessed ISIS as “severely degraded.”
- Militia attacks: Pentagon data show Iran-aligned militias launched more than 600 attacks on U.S. personnel and facilities between February and April 2026.
- Casualties: U.S. sources cite roughly 4,500 American service members killed in Iraq; Reuters reports 4,400 deaths.
Official Statements & Responses
U.S. officials said the United States will continue to provide training and intelligence assistance to Iraqi forces after the withdrawal.
Criticism & Opposition
Security analysts warn the exit removes a key counterweight to Iran-backed militias. Jassim al-Bahadli, an Iraqi security analyst, said past security vacuums have been dangerous. Renad Mansour, director of the Iraq Initiative at Chatham House, noted militias remain in “full-on war mode.” Saman Noah, a regional political analyst for CBS News, highlighted Iraqi doubt that the security apparatus can contain external aggression and internal armed groups without U.S. support.
On-the-Ground Reports
Kurdish officials expressed concern over the loss of U.S. air-defence systems that had intercepted Iranian drones and missiles. The Peshmerga Ministry reported more than 1,000 drone and ballistic-missile attacks on the Kurdish region since the February 28 2024 U.S.–Israel war with Iran began. Militia leader Abu Mujahid al-Assaf of Kataib Hezbollah celebrated the withdrawal as “the beginning of full sovereignty,” while warning the Iraqi government against “implementing American plans.”
Conflicting Reports & Gaps
- U.S. death toll: Sources differ between 4,500 and 4,400 fatalities.
- Militia disarmament timeline: The original September 30 2026 deadline has been pushed to June 30 2027, with no concrete schedule for weapon hand-overs.
- Future U.S. role: The extent of on-the-ground assistance after the withdrawal remains unclear.
What’s Next
Iraqi authorities have announced a 90-day cease-fire period for armed groups, after which weapons are to be surrendered gradually, with the final deadline set for June 30 2027. The U.S. task force overseeing anti-ISIS operations has relocated its headquarters to Jordan and will maintain a “ready” posture in the region, according to CENTCOM. Analysts such as Douglas Silliman warn that Baghdad faces difficult decisions as it balances militia integration, Kurdish security concerns, and the broader Iran-U.S. confrontation.
