Have a look at this mears.

US forces have no legitimacy with the vast majority of Iraqis, their current plan, the latest of several failed approaches is to train up Iraqis to take their place on the streets. All they've managed to do so far is create a few moderately efficient shiite death squads and some largely useless light forces with zero morale, shit equipment, less than three weeks training and the metaphorical equivalent of a big target on their back, half of whom are probably also working for the resistance. Electricity and water don't work two years after Bush declared "Mission Accomplished" and heavily armed criminal gangs roam at will while fanatical jihadi's mortar pilgrims and the whole of Anbar province looks about ready to move into stage two guerilla warfare.
Meanwhile our leaders cannot admit they have failed and seek to shift blame.
Iraq is fast turning into a much larger Chechnya. We can expect it to breed terrorism directly and to judge by reports of its role in the radicalisation of our recent bombers, it is already indirectly causing people to get killed here.
Your people did this mears, you can't get away from that. They fucked it up utterly in a sustained display of ludicrous incompetence fit to rival Elphinstone, Custer, Raglan and Hitler in the annals of military stupidity.
