This June 12, 2012, photo shows a Syrian revolutionary flag waving atop a building on the outskirts of Aleppo, Syria. Syria's conflict is the most violent to emerge from last year's Arab Spring. The protests started peacefully but prompted a brutal crackdown by President Bashar Assad's government. The fighting has escalated into a civil war that has killed more than 30,000 people over the last year and a half, according to activists. Despite intervening in Libya, the United States has steered clear of taking military action or arming Syria's rebels. (AP Photo/Khalil Hamra, File)

Gen. Martin Dempsey, chairman of the Joint Chiefs of Staff, accompanied by Defense Secretary Leon E. Panetta, gestures during their joint news conference at the Pentagon on Thursday, Oct. 25, 2012. During the news conference, Mr. Panetta said the U.S. military did not intervene during the attack on the U.S. Consulate in Libya last month because it was over before the U.S. has sufficient information on which way to respond.
