Russia claimed that it was in Syria to help Assad destroy ISIS, and after establishing an air base there, Russian planes began attacking positions around Syria. Turns out, those positions weren't ISIS positions, but those held by anti-Assad Syrian rebels.
Obviously Russia is there solely to prop up the murderous Assad as an ally, not to kill ISIS. That may come later once Assad is once again firmly in control of Syria.
Putin knows that Obama is not only a weak metrosexual who cares more about imaginary climate change than American national security, but that he is hostile to the interests of his own country. Further, Putin knows that Obama cares only that his legacy includes that HE got the US out of the middle east, and that he cares not about the aftermath, which we now know includes a Russian political hegemony to replace the American presence there.
Unfortunately it's too late to do anything about it short of a limited fighting war with Russia in the air over Syria. We aren't going to get into that, Obama will pull back entirely before that happens.
Bottom line, Obama just got his lunch money taken away by the playground bully, Putin.
