Us troops were actively trying to stop schools with little girls from getting blown up. Countries infrastructure was rebuilt. Then we left.

No one is innocent but there are differences.

>Us troops were actively trying to stop schools with little girls from getting blown up

By blowing up other schools, hospitals, weddings, and countless of civilians?

War crimes are war crimes. And it's not like we don't know that the US is primarily interested in middle eastern oil, and not actually spreading peace in the region.

> the US is primarily interested in middle eastern oil

This is a very vague phrase. The US does things which seem to drive up the price of oil, and things that seem to drive it down. The US economy also involves consuming a lot of oil and producing a lot of oil. So I don't know how you relate foreign policy in the mideast to that. "Interest in oil" can explain anything, anything that raises the price and anything that lowers it, and therefore nothing. Blaming the defense industry makes more sense to me, except that the US defense industry can and does sell arms worldwide, so why do they particularly need the US to be involved in a war?
