And where's any compassion whatsoever for completely innocent women and children fleeing a war zone? That would be like me standing on the shore watching a little child drown just because it's not my child.

ISIS is in serious trouble and is falling apart, but splinter groups are going to be a long-standing problem.
A living Assad running part of Syria actually is probably preferable over ISIS running the same-- just take the word of the Israelis on that. Assad knows his constraints, but ISIS hadn't but is now learning.
BTW, what kind of economic pressure would you put on the Russians and why do you think that would work? Ever hear of "the Law of Unforeseen Consequences"?
