[RCP] There is a new cease-fire agreement in Syria, but this time without the U.S. at the negotiating table. Will it last when so many others have failed? William Brangham speaks with Andrew Tabler of the Washington Institute for Near East Policy and Joshua Landis of the University of Oklahoma about the symbolic significance of the move and what’s next for the rebels, the Assad regime and Syria.About the ceasefire negotations, Tabler said, "by pausing now and going into diplomacy, I think it shows that the Russians are setting the table for President-elect Trump to become involved in some sort of diplomatic process."
