The United States and Iran, having clinched a landmark interim deal suspending some aspects of Tehran's nuclear program in exchange for sanctions relief, turned their attention this week to addressing the humanitarian crisis in Syria.
The long-standing adversaries were scheduled to attend a dinner tonight hosted by Britain's ambassador to the United Nations in Geneva and participate tomorrow in U.N.-sponsored conference at the Palais de Nations aimed at persuading Syria's combatants to allow the delivery of humanitarian aid.
The conference -- which will bring key regional and international powers together -- will provide the first major test of whether progress on the nuclear front can be converted into political progress and an improvement in living conditions for millions of needy civilians in Syria.
