This is what we call balance of power. What was done regarding Iran by US in the past few years? Nothing. Russians are no big fans of Iran but in this case they will have more control that will be beneficial to everyone. Sadly we in US have no real politicians and diplomats in power who can play on the world stage.

Russia having control anywhere is never beneficial to everyone....it benefits Russia
