John Kerry, U.S. secretary of state, testifies before a Senate Foreign Relations Committee hearing in Washington, D.C., U.S., on Wednesday, Sept. 17, 2014. Although the country is threatened by Islamic extremists, ethnic resentments and sectarian schisms, Kerry says that promising political and diplomatic developments in the past month may help OPEC's second-largest oil producer avert a dire future that seemed all but certain.
