I'm no fool when it comes to what Russia is really doing here (protecting their strategic naval base), but it's nice to read that a world power is finally handling the Syrian Civil War with some actual common sense.
Let us not be mistaken, ISIS is the most powerful armed group fighting against the Assad regime, and is much more powerful than any armed rebel group. When the Assad regime falls, and they surely will given time without outside intervention, they will turn on these secondary rebel groups just as they have all the others in their path and destroy them as well. And since the entire Alawite population is Shiite, the world (namely Europe) will have a massive civilian exodus on its hands fleeing the slaughter, because ISIS will not spare a single one of them.
I don't mean to sound like an overly passionate nutbag about this, but I feel that the US and our European partners are not fully considering the ramifications of the desires that our allies, Turkey and Saudi Arabia, want in the region. I'm sorry, but our allies' stances are too tainted with sectarian intolerance to be taken seriously in this case. ISIS *will* slaughter all of the Alawites. If we don't start acting on our own best interests for a change, we're going to have a whole lot of blood and migrants on our hands.
