For me, Putin is playing an excellent hand.
Inside just five months the entire world knows that Russia has identified the mainstays of ISIS- our ' allies ' the Turks- and has dislodged ISIS and other anti-Assad militias which ' we ' support thus opening the way for Syria's LEGAL representatives to mop up. Of course, they will still have the benefit of Russia's intelligence network and highly efficient air force.
Putin has also left the West in a fine old mess. It cannot continue to arm the militias it supports and it cannot continue to allow the Turks to support ISIS without the entire world knowing about it. In effect Putin has created the conditions for the re-establishment of the legal Syrian state and is sitting in the wings watching in case any illegal protagonists ( that's ' us ' ) attempt to reignite the conflict.
Putin has also secured Russia's warm-water port at Tarsus and won the confidence of the Lebanese and the Iranians- future allies in the prevention of any Israeli efforts to make war with Iran.
Not a bad five months work, really.
We'd better get close to him- because he will make fools of Trump, Billary, Cameron, Allende and Merkel and their efforts to sustain the unsustainable ethnic-cleansing and warmongering doctrine of neoZionism. That's my take- and there is no sensible reason at all why the West cannot be partners with the Russian Federation.
Well, maybe that obvious mill-stone around the neck of the USA might prevent it.
