President Donald Trump declared in his first term that the Islamic State group was defeated and that U.S. troops would leave Syria. This weekend, a gunman linked to the Islamic State group killed two Iowa National Guardsmen and an American translator in Syria.
Syrian and U.S. troops were returning from a joint patrol on Saturday when a shooter attacked them at the gate of a military base in Palmyra, a former stronghold of the Islamic State group. U.S. Central Command described the attacker, who Syrian forces killed, as a "lone ISIS gunman." Trump wrote on social media that the shooting was an attack on America and Syria alike, vowing revenge.
