The withdrawal, agreed on two years ago, comes against the backdrop of the ongoing war between the United States and Iran that has also sometimes spilled over into Iraq, with Iran-backed terrorists firing on U.S. troops and the U.S. striking the groups' strongholds.
Baghdad touted the end of the U.S. mission as a sign of the country's increasing strength and sovereignty.
The withdrawal was also celebrated by Iran-backed groups but raised concerns among some other Iraqis, particularly in the Kurdish region. Meanwhile, questions loom around the future of the Iraqi militias, which the Baghdad government has sought — with little success so far — to disarm.
Pentagon spokesperson Sean Parnell said in a statement that U.S. troops and equipment had completed an “orderly departure” from the air base in Irbil, in northern Iraq's semi-autonomous Kurdish region.
“This milestone reflects the success of a 12-year campaign that defeated ISIS as an organized military threat in Iraq and across the region,” he said. “It also marks a transition from a wartime coalition mission to an Iraqi-led security effort supported by a more normal bilateral security relationship.”
Iraqi Prime Minister Ali al-Zaidi presided over the handover ceremony and described the U.S. withdrawal as the beginning of a “new phase, one defined by Iraq’s sovereignty, the strength of its institutions, the readiness of its forces, the unity of its decision-making, and balanced partnerships with its friends.”
He said Iraqi security forces will continue the fight against IS and the government will ensure that non-state groups no longer hold weapons.
U.S. troops invaded Iraq in 2003 to topple Saddam Hussein. They departed in 2011, but three years later, Iraqi authorities invited a smaller U.S.-led mission to fight the Islamic State group, which had rampaged across Iraq, seizing large swaths of territory.
With the terrorist group reduced to scattered sleeper cells, Washington and Baghdad agreed in 2024 to wind the mission down.
