“I do not believe we are going to get a peace agreement in Syria. We are going to keep having these talks in Geneva,” Rubin told foreign reporters at the Democratic National Convention.
He added that the Russians “have leverage” in the negotiations, but the United States does not “because we have played such a modest role” politically and militarily.
Democratic presidential nominee Hillary Clinton would advocate “a much broader role” for the United States in the Syrian conflict, if she becomes president, Rubin said.
President Barack Obama has remained committed to coordinating with Russia to facilitate a political transition in Syria and an end to that country’s five-year civil war.
