Well, show us what you've seen, because I am unaware of any such negotiation. From what I understand, the US gave Iraq some chemicals that were later used to create chemical weapons. And I don't think Rumsfeld had anything to do with it. I could be wrong, of course.For example, the US gave chemical weapons to Iraq in 1983 (?) to use against Iran. Donald Rumsfeld, from what I've seen, was the chief negotiator in this weapons deal.
As for Afghanistan, I would hardly call the US' involvement murder. And isn't Afghanistan in the Orient, not the Middle East?
