The Iraqi army cant cope with ISIS, because they wont fight in sunni territory. Once ISIS reaches shia "heartland", they´ll struggle to advance, because shia militars will actually start to fight them. What would be the point of american ground-troops?
I red about these other groups. Apparently a ex-FSA commander leading a small group of fighters, who use guerrilla warfare to kill some ISIS soldiers. Good read, but it has absolutely no significance for the war.
The battle of Kobane is important but it wont be a turning point. ISIS wont be able to take over the rest of syria and Assad wont be able to regain control over the whole country. Regardless of whats going to happen to Kobane, there will be a stalemate for now.
The big question is, whats going to happen once ISIS took over Anbar and starts to attack Baghdad.
