The effect of British policy on Iraqi public opinion should be considered too. If the following quote from a TimesOnLine story is in any way typical of that opinion, the policy has been a disaster.

'He had less of a glowing impression of the British military, which had control of security in Basra from March 2003 until December 2007, a period that saw the al-Mehdi Army militia grow in strength and influence.

"British forces did not make an impression on the people of Basra. They let the militia control the city and stayed away from events."

Ms Ali was also unimpressed, describing the British troops as lodgers.

"As we know, people who rent stay away from trouble even if it is harming the house he has rented," she said.

"In my personal opinion, although I have no expertise, the US forces always want to appear strong and able to succeed in any battle. They will never allow militias to ruin the reputation of the US army."'
