Documents approved by Cheney in 2001 show that the main motive for invading Iraq was the fear Saddam Hussein might manipulate oil markets by temporarily interrupting oil sales.

Surely this goal could have been achieved with some sort of a deal.

The article also cites proof that the US planned, before the invasion, to rule Iraq as a colony with oil extraction as the priority.

Every country needs to aim for independence from oil supply, by developing renewable energy supply as an urgent national priority. When fossil fuel companies and their pet politicians block this, they are effectively working against their own country.
