Via ID, it appears that the Russian aircraft carrier Admiral Kuznetsov is deploying from Murmansk to the Mediterranean. The expectation seems to be that she will operate (at least for a short period) out of the Syrian port of Tartus, which has been the focal point of negotiations between Russia and Syria for quite some time. Ironically enough, Admiral Kuznetsov was originally named Tbilisi.
A couple thoughts... Kuznetsov deployed to the Med for exercises last year, so this isn't a radically unusual move. Still, I think it has to be interpreted as yet another "No, we really are serious" message from the Russians to the West. Kuznetsov is the largest, most powerful unit in the Russian Navy (excepting SSBNs), and moving her invariably carries political as well as military significance. And although Russia has been engaged in negotiations with Syria over the base at Tartus for a while, I still have to wonder if the Russians don't relish this deployment as an opportunity to send a message to Israel. Noah Shachtman has a fine post at Danger Room discussing the extent of Israeli military cooperation with Georgia, a relationship that the Russians are now complaining loudly about. Noah also notes that the Israelis saw the danger of war, and decided to substantially cut back on arms shipments to Georgia at the end of the last year. This included canceling a deal for Merkava tanks. The Israeli justification for slowing down cooperation was the need to maintain good relations with Russia in order to place additional pressure on Iran.
