Palestinian President Mahmoud Abbas is in New York this week, to attend the United Nations General Assembly with plans to apply for full membership of a Palestinian State. The U.S. has made it clear it will veto the application, and there are fears that that may spark renewed violence. But the Palestinians believe statehood might open the door to renewed stability and opportunity. Philip Alston, professor of law at New York University, discusses the process of becoming a state and what barriers the Palestinians will face at the U.N.
