That means something is up. Russian state media going quiet means that, either, the apparatus is confused and doesn’t know what to do (which in Russian terms usually precipitates a change in the top leadership), or, more ominously and far more likely, something the west will find pretty big is up. They’ve called up an unscheduled meeting of the CIS. Whatever it is, it’ll most likely be anounced there.
My personal take on all of this is that we are still fighting a cold war. Georgia and Serbia are pawns in the game.
