If you haven't seen it yet, the article referenced here is well worth the 10 minutes or so it will take to review it. The reason why the Bush regime invaded Iraq was to seize control of their oil -- obviously. However the article covers how the US is attempting to seize control of the oil while at the same time defend their theft attempt in the North and South of Iraq from the people who actually own the oil: the Iraqi people.
The best hope of the Iraqi freedom fighters is to continue to target the oil infrastructure to ensure that the fascist regime does not profit for their war crime atrocities against humanity. Even more so, were the Bush regime able to manage to steal the country's oil, that would embolden other nations to try to pull the same mass crime against other oil producing nations.
Reducing the nation's reliance on oil is a phenomena that _will_ eventually have to take place, and the US and other fascist regimes will eventually be forced to impose extensive, massive rationing. But that won't happen so long as these fascist regimes are willing to engage in indiscriminate, massive, wonton slaughter of brown people who stand on top of oil. If the people fighting for their lives, their children's lives, their country, and their nation's oil were to focus on targeting the oil infrastructure to ensure that Unocal, Exxon/Mobile, and the rest of the fascist corporate regimes can't steal the oil, petrolium rationing in the industralized nations will be forced upon the populace that much sooner.
