Putin supports the Assad regime, yes.
Russia's bombing is of many anti Assad groupings more than Isil.
The US created Isil? Yes they withdrew from their misguided Iraqi adventure leaving a power vacuum that Isil exploited.
But if you think Putin is a model of anything other than power hungry rapaciousness and maintenance of wealth and power in the hands of a small Russian elite(that do not threaten him) you are as deluded as the ordinary Russians who will never believe in anything other than an authoritarian, rigid Russia jealous of its position in the world.
