Right. In fact is is logical to refine crude oil near the point of origin, before shipping, especially if the point of origin has lower labor and environmental costs, compared to US based refineries.
No, but it is difficult to guess to which troop deployment strategy will get the oil flowing for freely the quickest. IMHO we need to win the war in Afghanistan (and where ever) against organized terrorism... As noted above, I'm not sure we have a refinery capacity problem, in the long run.
It's not just about oil, or even WMD. Bush just wanted to finish the job his daddy started.
