Sorry, I forgot to mention. The US forces have done, and continue to do an outstanding job in an impossible situation. Even if they had put 500,000 troops into Iraq they would still be hard pressed to try and control the country. There are a lot of foreign mercenary interests who are determined to see the USA fail in Iraq; that is one major factor that makes it a no win situation. I reiterate that it should have been accomplished the first time, when Iraq invaded Kuwait. The only way the US army will be able to establish control is if Iraq can establish reasonable government, and reform its military and police. Since this is unlikely to happen quickly, they must plan for a long term stay.
