It was always about securing Iraq's oil resource for western consumption. This didn't mean we were 'stealing' the oil in the conventional sense of not paying for it, it meant the oil would be controlled by US interests and wouldn't go to russia/china except at our behest, and certainly wouldn't go to them without us having opportunity to participate.

With Saddam in power, he was selling primarily to Russia and China and a bit to France. That didn't make bush's oil buddies very happy and bush had the double-bonus that he could argue making the US military fight wars to make his buddies profit was also giving the US a strategic advantage in controlling Iraq's vast oil resource. I.e. Sure it was good for his buddies, but it was good for the US as well (except for the thousands of dead US/British soldiers and hundreds of thousands of dead Iraqis).

Its not worth arguing with anyone who thinks it wasn't about oil. Such people are deluding themselves too much to consider reality.
