US plans to run Iraq for two years

The strategy behind this is to set up a major oil producer as a vassal state. My guess is that this state would 1) not participate in OPEC, 2) pump enough oil to ensure a price of $15 a barrel, 3) award major contracts to US oil companies, 4) pay the US $50-$100 b in cost recoupment, and 5) serve as a staging ground for intervention in other oil producing states that become radicalized as a result of this invasion.

Based on this WSJ article... does it seem to anyone else that this is showing itself to be much more that protecting ourselvs, and we may actually be planning to take over the country simply for the oil (as John seems to believe)?
