The problem is, that they will win no matter what we do.
All we can do is attempt a holding operation, as someone said "you cant bomb an ideology".
That is why we must be pragmatic, stop fighting amongst ourselves, jockeying for short term political advantage.
Russia has offered full support to a UN led coalition but we are knocking it back because of our stupid(or self serving)ideology.

They say we cannot join forces with a man who was killing his own people. He was fighting a brutal, fanatical armed insurgency, in the only way possible.....with everything at his disposal.

We are unwilling to supply ground troops, the so called FSA is untrustworthy.....we need to work out a strategy and that strategy must include Russia Iran and Assad.....We must unite against this brutal monster ISIS.....if only to gain a few more decades.
