In this image released by the Department of Defense, a U.S. Air Force B-1 Bomber separates from the boom pod after receiving fuel from an Air Force KC-135 Stratotanker on April 13, 2018, en route to strike chemical weapons targets in Syria. President Donald Trump declared “Mission Accomplished” for a U.S.-led allied missile attack on Syria’s chemical weapons program, but the Pentagon said the pummeling of three chemical-related facilities left enough others intact to enable the Assad government to use banned weapons against civilians if it chooses.
