Unfortunately, the Russians are the key players in the Syrian conflict since Obama let it slip off from his control. John Kerry’s efforts, along with the others, to promote at least a temporary ceasefire there are noteworthy. At this time Obama can once again cease the initiative by inviting Putin, along with his European, Turkish, and Saudi counterparts, to negotiate peace in Syria. But he seems to have abandoned Syria, leaving it for Kerry to work out something. That is rather unfortunate.
