It's pretty simple, Teribus. Bush intends to palce a military governor in charge of Iraq during the occupation. This military governor will undoubtedly have some degree of control over where oil and other exports can be sold to, as it is a perfectly legitimate function of the government. It would be very surprising indeed if American oil companies, possibly ones with connections to Bush, did not get awarded a certain percentage of these contracts. Even if all that happens is that the current contracts with France and Russia are invalidated, and the market is opened to American companies, they still gain considerably.
