Even as President Donald Trump mulls a U.S. pullout, insisting that the Islamic State is “almost completely defeated,” the extremist group is showing signs of resurgence in Syria. Talk of a U.S. troop withdrawal has alarmed the Unites States’ main ally in Syria, the Kurds, who fought alongside the Americans to roll back the Islamic State group. (AP Photo/Hussein Malla)
