Following Thursday’s self-destruction bomb attack on a Kabul air terminal, U.S. military officers vowed to hunt out the Islamic State’s leaders, vowing to exact vengeance on the long-time U.S. foe for the deaths of many Afghans and U.S. personnel. The Islamic State terrorist group (ISIS) has claimed credit for a deadly attack that killed at least twelve U.S. military personnel and a handful of Afghans in what was supposed to be the last days of the U.S. pullout from Afghanistan.
