I agree with you. Although what he said is correct, saying in such a crude way unfortunately helps it ridiculed and disqualified easily which leads to the repetition of it. Unfortunately not by mistake but in consequence of poor communication like that which results sheer encouragement of conspirators to try again for another war.

The mistake most make when criticizing US is when they put all the US into one bag. Like any country there are many competing forces in the US. Especially a country like US, big and dominant, those forces are trying pull and bend the public opinion for their own agenda. That said arguing that it was for the oil (in the literal sense) without substantiating it only good for self-debunking. I think it would be known by now if Iraq's oil was really stolen (literally shipped overseas). I do not believe in that. Hegemony is all about controlling others so was the reason of this war. What has US gained can not be described in one sentence, especially if that sentence is just a rant. As much as it gained something she lost a lot as well, especially average American and multiples of it by the poor Iraqi people. Corporations, special interest groups and countries in that region which has deep and dirty ties with the congress (interestingly Iran as well) gained a lot.
