President Barack Obama speaks to a crowd of military personnel at U.S. Central Command at MacDill Air Force Base in Tampa, Fla., Wednesday, Sept. 17, 2014. The White House and the Pentagon are grappling with how to explain what American military forces are doing and could do in Iraq as they battle the Islamic State militants. Obama reiterated his pledge to keep American troops out of combat missions. But hours later, Vice President Joe Biden appeared to be less certain about ground troops. Biden's remarks echoed comments a day earlier from Army Gen. Martin Dempsey, the Joint Chiefs chairman, who said he may, if necessary, recommend to the president that U.S. ground forces accompany Iraqi troops on attacks against Islamic State targets, particularly in certain complex missions or if there were threats to the U.S.(AP Photo/Phelan M.
