Finding Islamic State militants to kill is not easy, the top U.S. commander overseeing the air war in Iraq and Syria said. Air Force Lt. Gen. John Hesterman says U.S. pilots are hitting as many targets as they can find, and to suggest otherwise is simply wrong. "The thought that we are observing large numbers of Daesh terrorist and not killing them anywhere is fiction," Hesterman said Friday in a rare briefing for Pentagon reporters from his headquarters in Qatar. "That is patently false," said Hesterman, the commander for U.S. Air Forces Central Command.
