Ok on many other points, but, I just cannot even come close to believing this was the motivation. I mean, we certainly aren't benefiting in any manner from Iraqi oil.
It isn't shipped to us for free, nor used really to repay any war costs, etc.
If the war was for oil, and US imperialism to take over that country for oil, I'd have thought we'd at least have seen the oil benefits by now.
The goal of war was not to make oil cheaper for you the regular American. Instead the idea was that several corporations affiliated with Bush administration (i.e. halliburton, Exxon, etc) will get exclusive contracts on Iraqi oil (and as military contractors during wartime, see Halliburton again, Blackwater). Iraq was was not profitable for United States as a country, but it certainly was profitable for Dick Cheney as an individual. So "we" has seen the oil benefits, it's just that you and me aren't part of that "we" crowd.
For God's sake, stop researching for a while and begin to think!
