'Russia is somewhat more vulnerable to the West’s teaming up with Sunni radicals as its new geo-strategic weapon of choice.'

"... Russia is not frightened by sanctions (which some, with influence in Moscow, would welcome as a chance to push-back against the US use of the global interbank payment systems for its own ends). Nor is Russia concerned that, as occurred with the USSR, the US – in today’s changed circumstances – can contrive a drop in the price of oil in order to weaken the state. But Russia is somewhat more vulnerable to the West’s teaming up with Sunni radicals as its new geo-strategic weapon of choice.  
We have therefore seen a Russian outreach both to Saudi Arabia and Egypt (President Putin recently extolled King Abdallah’s “wisdom”). There is a feeling too that US policy is not fully controlled by the US President; and that Gulf States, smelling that US policy may be adrift, and open to manipulation by interests within the US, will take advantage (perhaps in coordination with certain Americans opposed to President Obama’s policies) to escalate the jihadist war against President Assad and to target Obama’s Iran policy.  Russia may be expected to try to circumscribe this danger to its own Muslim population and to that of its neighbouring former Soviet Republics.  But for now, Russia will be likely to play it cool: to wait-and-see how events unfold, before recalibrating any main components of its Middle East policy.  For the longer term however, Russia’s effective divorce out of the unipolar international order will impact powerfully on the Middle East, where Saudi Arabia (not to say Syria and Iran) have already virtually done the same."
