To be fair, the troops have not been the best-supported they could be. What has really blighted that after-war years has been the attitude of the troops. I used to think that the British troops were being nice and the US troops were being nasty to Iraqis. I still do think that the British troops have a more friendly attitude in general. However, both forces have contained people who think it's funny to abuse prisoners. To an extent, you can't tell who will do this until it happens. However, I think tighter tabs should have been kept on the troops to prevent these breaches of human rights. It is the abuse of prisoners, more than anything else, that has lost the occupiers the trust of the Iraqi people.
It could be claimed to be the fault of the military for employing them in the first place without adequate screening. Personally I would not place such a ridiculously heavy burden on the recruitment department. Similarly, keeping a close watch on every soldier would be impractical and an invasion of privacy. However, you must realise that American and British troops as not very popular in Iraq at the moment. Few people trust them.
