If true then ISIS is overextended and very vulnerable to a well planned counterattack. With American air support, the Iraqis just might be able to do it with the Shi’ite volunteers and Iranian support. Despite what Iran says, the fall of Baghdad or the establishment of an ISIS state would be a strategic disaster for Iran. They will do what they can to defeat ISIS and will not complain if the US provides air support.
I’m not entirely sure this is so bad for Tehran. ISIS is not going to turn around and attack Iran once they’ve taken Iraq. They’ve made clear their targets are the domino line of Sunni monarchies, who are Iran’s arch enemies.
If I was Iran, would I rather face the US backed cabal of oil sheiks or a disorganized band of fanatics with no running water and no international recognition.
The crazy thing is, though nobody is saying they support ISIS, each country has potential gains in their success. Thats why its very hard to figure out who to trust.
“the fall of Baghdad or the establishment of an ISIS state would be a strategic disaster for Iran.” — Agreed. Especially now that Obama also refocusing on overthrowing Assad in Syria.
