Now we turn to a showdown of world tightens, vladimir putin in a public dual with president obama about global leadership, strength and why the syrians say they are really giving up chemical weapons. Abc's chief global affairs correspondent martha raddatz. Reporter: The president voicing a possible deal on syria. I am hopeful that discussions that secretary kerry had with foreign minister lavrov can yield a concrete result. Reporter: When asked about vladimir putin's talk splashed across the "new york times," silence. It's no wonder, putin portraying himself as a man of peace, challenging the idea that america is an exceptional country, saying we're all qualm and warning president obama that his threat of a military strike means millions around the world see america as relying solely on brought force. I just turned knots in my stomach because how could he believe that he could come to the united states via this op-ed and try to divide the american people. It made me nauseous to be very honest with you. Reporter: But assad an russian tv rubbed it in even further. Syria is handing over its chemical weapons under international supervision because of russia, the u.S. Threats did not influence the decision. Syria today said it wanted 30 days to provide technical data on its chemical weapons. Secretary kerry said the u.S. Would need more than words. This is not a game, he said. But with the atto knowishing turn of events in the past week it sometimes seems like one with russia's putin playing quarterback. The u.S. Says the russians have to prove it and that test will play out over the next few weeks.
