If Russia succeeds ( and the Americans with their French and British lackeys are putting up resistance by their demands), it will boost the prestige of Russia and the stature of Putin, not only in the Middle East but elsewhere in the world where they will be called upon as "honest brokers". The Russians will get to keep their warm water port in Syria; will become an important player in the Middle east ( which they had lost after the fall of the USSR); in the Israel/ Palestine issue; in Egypt, Yemen, Libya, Iraq and elsewhere. They will get indirect relief in Dagestan and Chechnya, where they continue to battle Islamic forces and al Qaeda. As Russia rebounds on the world stage, it brings some balance and offset the American dominance, which has allowed it to act without restraint.
The most important issue however, is the continued civil war in Syria. There is the possibility that if the Russians succeed on bringing Assad on board, that this could lead to a broader peace and the end of the civil war in Syria. That would be a resounding victory for the Middle East and the world. It will show that, with USA and Russia working together, the volatility and the violence, which has been rampant since the end of the Cold War, can be reduced.
There is a great opportunity here and must be seized. Obama has said that he was elected to end wars. If he still believes this, then he must work with the Russians. National pride and ideological bias be damned, work together to advance peace.
