We Americans have Donald Trump and the world has Vladimir Putin. Trump is a shouter and bully who has never done much other than push around some people who work for him, but Vladimir Putin is now pushing around a lot of people in the Middle East after getting his way in the Ukraine. Putin is now the main player in Syria and intends to make the world pay attention to his demands that Russia be respected and allowed to make important decisions. Unlike Trump,he knows how to gain power in the world other than shouting and ranting.
There is no question that the entry of Russian air power, special forces, and extensive bombing have resulted in a significant decline opposition groups in Syria. His strategy is clear. Bomb the hell out of those opposing President Assad, but ignore ISIS. In fact, he uses ISIS to get rid of those seeking to gain traction in the fight to end the power of Assad.
Putin also seeks to make thousands flee Syria and head for Europe. He wants to create a refugee crisis in order to destabilize the European Union. A demoralized EU means it can not exert power to thwart his efforts to become the dominant player in Europe. Sorry Donald, he would eat you up in five minutes because Vladimir Putin understands how to handle a bully. After all, he has been one all his life and become quite successful.
