FILE - In this Friday, Jan. 11, 2013 file citizen journalism image provided by Edlib News Network, ENN, which has been authenticated based on its contents and other AP reporting, rebels from al-Qaida affiliated Jabhat al-Nusra waving their brigade flag as they step on the top of a Syrian air force helicopter, at Taftanaz air base that was captured by the rebels, in Idlib province, northern Syria. President Barack Obama said early on in the 2 1/2-year-old conflict that Assad lost the right to lead because of the brutal oppression of his people, most chillingly displayed in what Washington contends was an Aug. 21 chemical weapons attack on rebel-held areas that killed hundreds of civilians. But it’s not clear who would replace Assad if he were to be driven from power, either as a result of U.S. punitive strikes for the suspected poison gas attacks or in eventual political transition talks with the Western-backed opposition. The Arabic words on the flag reads, "There is no God only God and Mohamad his prophet, Jabhat al-Nusra." (AP Photo/Edlib News Network ENN, File) less
