Well my 2 cents on it is:
The reason why ISIS made the gains they did was cause the sunni military officers abandoned ship and the lower folks in the army, with no leadership, abandoned ship too.
The lower folks in the Iraq military that abandoned ship are now sprouting cacti in their desert mass grave.
The shia will fight to the death.
The shia dominated Iraq army outnumber the ISIS depending on what you read by about anywhere from 5 to 15 to one.
The sunni folks in these towns will hate the ISIS folks.
The conclusion I draw is that there will be a lot of bloodshed, with the Iraqi army eventually winning. That will probably take us up to maybe 2016.
It could have all been avoided if obumbles would have negotiated a status of force agreement. He didn't want it, he wanted to withdraw, he got what he wanted and this is the result.
Personally I think it is a good thing. I want these ordinary muzzies to see what their religion has spawned. I think we should arm both sides. As long as they are fighting each other they will leave us alone.
