I am sure most of us will appreciate the magnanimity of Moqtada Al Sadr in controlling the forces of the 'Mahdi Army' recently, his gesture has allowed the safe withdrawal of troops from a hopeless position to one of relative safety without bloodshed.
Hopefully we will now see the safe return of our troops, providing they are allowed to fly out of the region they now occupy.
Not such a pretty picture for the main aggressors I fear, the US forces will not be able to retreat now since the route of entry is under the control of opposing forces, they will either have to head North and beg assistance from Turkey, negotiate with Syria, (which they are already doing). OR, consider the sensible option and surrender.
There is also the option of attacking Iran of course, that way they may be able to drag other nations into their mess, assuming they can convince them that Iran has weapons of mass destruction.
Quite an interesting turn of events, quite embarrassing I reckon.
