What happens when the US pulls out of Iraq.

[Esmoreit]

If the US pulls out, you can expect something similair as to what happened in Basra a few months ago. The newly established Iraqi army was ordered to retake control of Basra after insurgents captured a few blocks.

After the fighting was done, a few divisions did not want to partake in fighting their brothers and even left weapons behind.
The coalition had to go in to retake control.

Expect Iraq to descend further into chaos and even civil war once the coalition pulls out. In the long run I wouldn't be to surprised if Iran sweeps in to take over from the "American minded government"
