The US is withdrawing its forces from Syria, ending a military presence of about 1,000 troops that lasted for a decade. This move follows the new Syrian government, led by President Ahmed al-Sharaa, taking control of the fight against terror groups. A senior US official said a large US troop presence is no longer needed but the US will stay alert to Islamic State threats. Last week, the Syrian army took control of the Al-Tanf military base from US forces. Al-Tanf was a key site in southeast Syria where the US had a military presence for years. Al-Sharaa joined the US-led coalition to defeat ISIS, gaining American sanctions relief and support to manage Kurdish areas in the northeast. ISIS still operates in Syria and remains dangerous. In December, ISIS killed two US Army soldiers and an interpreter in Palmyra. In recent months, US forces have attacked more than 100 ISIS targets and killed or captured over 50 militants. The Trump administration is managing a careful transition but preparing to respond if ISIS threats rise again.
