In the end, Russia will not only settle in Syria but also bring in all the necessary military hardware to aim at countries around as it has some valid excuses to do so now.

This fits in with the bombastic russian duma MP and head of the liberal democrats of Russia, Vladimir Zhirinovskys thinking, Russian soldiers washing their boots in the warm waters of the Indian Ocean, or the push south. They want to prevent ISIS from taking hold in the Caucasus/Central Asia (it sees this region as it's backyard and zone of influence), and thus posing a threat to the russian border itself.
