The announcement fueled concern about how quickly the U.S. will abandon its Kurdish allies, amid contradictory statements recently by administration officials on an exit timetable.
The withdrawal began with shipments of military equipment, U.S. defense officials said. But in coming weeks, the contingent of about 2,000 troops is expected to depart even as the White House vows to keep pressure on the Islamic State group.
Once the troops are gone, the U.S. will have ended three years of organizing, arming, advising and providing air cover for Syrian, Kurdish and Arab fighters in an open-ended campaign devised by the Obama administration to deal the IS group a lasting defeat.
Uncertainty over the timing and terms of the Syria pullout have raised questions about the Trump administration’s broader strategy for fighting Islamic extremism, including Trump’s stated intention to reduce U.S. forces in Afghanistan this summer.
U.S. airstrikes against IS in Syria began in September 2014, and ground troops moved in the following year in small numbers.
The U.S. military has a limited network of bases inside Syria. Troops work mostly out of small camps in remote parts of the country’s northeast. Also, U.S. troops are among 200 to 300 coalition troops at a garrison in southern Syria known as al-Tanf, where they train and accompany local Syrian opposition forces on patrols to counter the IS group. Al-Tanf is on a vital road linking Iranian-backed forces from Tehran all the way to southern Lebanon — and Israel’s doorstep.
Trump’s decision to leave Syria, which he initially said would be rapid but later slowed down, shocked U.S. allies and angered the Kurds in Syria, who are vulnerable to attack by Turkey. It also prompted the resignation of Defense Secretary Jim Mattis and drew criticism in Congress.
