Other than what you have stated, I don’t give a crap anymore. We spent billions and billions of dollars “training” the Iraqi military as well as giving them billion and billions of dollars worth of our equipment not to mention American blood by the 55 gallon barrel. As a result my opinion is:
The Iraqis can’t fight, or else they are chickensh*ts. They lose almost every engagement against the ISIS. Looks like the bad guys are the only ones that will fight. So as far as I am concerned, Iraq can go to hell.
Im surprised that Iran cant control a Sunni area. Well maybe not so much surprised.
