My gut reaction is that this is dis-info.
I expect this will probably happen at some point under one of two distinct scenarios:
1) Russia decides to capitulate to the West (and/or West+China.)
2) The Western influence in the Middle East collapses and Russia and Iran (who are natural adversaries due to geographical and natural resource consideration) move toward a more aggressive jockeying for position against one another.
I don't see any indication of either of these prerequisites. That doesn't mean they are not occurring however.
Edit: I should state option 3) which is more possible: Russia is simply giving up a rook or pawn that they know is lost.
1) Russia decides to capitulate to the West (and/or West+China.)
not gonna happen
2) The Western influence in the Middle East collapses
not gonna happen
3) which is more possible: Russia is simply giving up a rook or pawn that they know is lost.
not gonna happen
i would vite for option 4 - ISIS will take control over syric and iraq completely
