What is Russia's endgame? That has not changed much: stall, maintain the status quo as long as possible. It is for this reason that Russian ships continue to cruise around in Tartus and that Moscow keeps sending arms to Damascus. The Russian ships and the anti-aircraft missiles will not be used against the rebels -- who have no planes or ships -- but, rather, are Russia’s way of maintaining equilibrium. If the Saudis and Qataris arm the rebels, Russia will arm Assad. If the West makes moves to intervene, Russia ships and anti-aircraft supplies will have made the moves exponentially more risky. But the reality, as familiar as it is, is evolving, and it's making it increasingly difficult for Russia to tread water. “Russia would prefer a status quo, yes, but everyone here understands that a status quo no longer exists,” says Fyodr Lukyanov, the editor of Russia in Global Affairs. “It’s a slowly disintegrating situation. The erosion of the regime is acknowledged by all, but what is the time horizon? How long will it take till it finally crumbles? Russia can wait, but the U.S. can’t.”
