It's good-great news
It's too risky
Its good that their helping to fight ISIS but we should remain weary of their presence there.
Good. Glad to see other countries doing their part in the middle east. America needs a break from being the world's police.
Well even though i am not trusting them. If it is to fight ISIS then well you know the saying the enemy of my enemy is my friend. Also we need someone to stop ISIS.
Even though it's unlikely that Russia is acting on behalf of the world, I care more about what they might achieve than their motivation. They are closer to the ISIS origins and less restrained than the US (we can only have a war if nobody dies), and they might actually solve the problem. Let them have the show (and the expense) for a change. And if they are tied up with ISIS and the Middle East, it's unlikely they would go after the US. The US could use the break to work on problems at home.
The last time Russia got involved in the middle east directly, over 2 million Afghans died.
if you think Russia has good intentions, you would be lying to yourself.
Russia is an ally of Assad.
Russia is not going to loose that base in Syria it seems no matter what. Prepare for even more people fleeing and things to get worse before they get better. The plus side is the region may become stable once they are their and everyone's either fled or dead.
