One of two things are going to happen before the election next year.
Either they are going to cut and run from Iraq OR they are going to depend upon massive propoganda to make it seem like they are reducing troops.
Cut and Run Option
In this option they essentially slap together a rag-tag, untrustworthy Iraqi security force, throw together a constitution and have a sham election, declare mission accomplished and pull out, leaving the country in shambles. In this scenario they will possibly leave some troops in the country behind the walls of heavily fortified Halliburton built military fortresses. These troops and bases will be used for further imperialist ventures and possibly protect some oil fields and refineries. Although they may decide to give up on Iraq's oil for the moment and just use the bases as staging grounds to launch more invasions in the region.
Propoganda Option
The troops will stay but they will depend on fudging and making up numbers and confusing the public through tricks involving troop rotations and deployments. They will claim that they are cutting down the number of troops deployed, when in fact they are not. They will depend on propoganda to make it seem like the troops will be home any moment now. This is another version of what they intend to do w/ the economy "Prosperity is right around the corner!" "All the troops will be home any day now!"
