SYRIA CRISIS / IRAN Emanuele Ottolenghi, Senior Fellow at the Foundation for Defense of Democracies and Daniel Serwer, Professor of Conflict Management and Senior Fellow at the Center for Transatlantic Relations at the Johns Hopkins School of Advanced International Studies, tell VOA that by denying it is responsible for launching the chemical weapons attack, the Assad regime is merely “playing for time.”  They discuss with host Carol Castiel the daunting logistical and political obstacles to implementing the US-Russia deal to dismantle Syria’s chemical weapons and obtaining a strong  UN resolution to compel compliance; reaction from the beleaguered Syrian rebel opposition; challenges to reviving “Geneva Two”; implications for Iran; and perception of US credibility in the region.
