In this Saturday, Sept. 27, 2014 photo released by the U.S. Air Force, Staff Sgt. Chris O'Donnell, 340th Expeditionary Air Refueling Squadron boom operator, looks out at a B-1B Lancer during a refueling mission during U.S.-led coalition airstrikes on Islamic State group targets in Syria. Nearly 2 out of 3 Americans back U.S. airstrikes to combat Islamic extremists and half also think there's a high risk of a future terrorist attack on American soil. Americans surveyed for an Associated Press-GfK poll are split on whether they approve of the way President Barack Obama is generally handling the threat from the Islamic State group and other terrorists. Yet despite more than a decade of costly war, about a third favor going even beyond airstrikes and putting U.S. military boots on the ground in Iraq or Syria Ñ something Obama says he has no plans to do.
