pretty much, crush the saddam regime and put a "friendly" regime in its place to secure the US oil flow ....
+they can cover their asses with humanitarian shit, building schools and hospitals, teaching their farmers, building up a decent form of law enforcement, making sure the iraqis rule their own land exactly like the US wants them to ...
why else would the US be fighting in that dessert ?
if they'd be all so concerned about corrupt regimes and mal treatment of people, why don't they go rage war in africa, that shit's much worst, only difference would be that the US has no direct interest in those regions ....
