Russia is just going to be an ISIS target with the 200 troops and 6 tanks they have in Syria.
Assad has already lost most of his country, he won’t be able to take it back with that assistance.
ISIS is already using it for recruiting, Muslims from the Caucasus and Chechnya are heading there literally looking for Russian heads.
Obama is trying to finesse ISIS and it’s not going to end well.
Russia has dropped a significant amount of personnel and hardware in Syria. They’ve established an SLOC and an ALOC. I don’t think they’re there for limited contingency operations.
They may get chewed up like they did in Afghanistan, but no matter who loses, we win, as they grind each other down.
