The United States launched airstrikes in Syria on Thursday, targeting facilities near the Iraqi border used by Iranian-backed militia groups. The Pentagon said the strikes were retaliation for a rocket attack in Iraq earlier this month that killed one civilian contractor and wounded a U.S. service member and other coalition troops. The airstrike was the first military action undertaken by the Biden administration, which in its first weeks has emphasized its intent to put more focus on the challenges posed by China, even as Mideast threats persist. Biden's decision to attack in Syria did not appear to signal an intention to widen U.S. military involvement in the region but rather to demonstrate a will to defend U.S. troops in Iraq. “I’m confident in the target that we went after, we know what we hit,” Defense Secretary Lloyd Austin told reporters flying with him from California to Washington. Speaking shortly after the airstrikes, he added, “We’re confident that that target was being used by the same Shia militants that conducted the strikes," referring to a Feb. 15 rocket attack in northern Iraq that killed one civilian contractor and wounded a U.S. service member and other coalition personnel. Austin said he recommended the action to Biden. “We said a number of times that we will respond on our timeline,” Austin said. "We wanted to be sure of the connectivity and we wanted to be sure that we had the right targets.” Earlier, Pentagon spokesman John Kirby said the U.S. action was a “proportionate military response” taken together with diplomatic measures, including consultation with coalition partners.
