The petro-dollar agreement is with Saudi Arabia only. The rest do as well only because of the establishment of the system. I honestly do not know why we're at war so much in ME except to keep our economy going when it should have died years ago. While it's easy to say "It's for the oil", we're not getting the profits of it, we're only getting deeper in debt.Yeah, I read about that recently, how gold was illegal and they went around collecting it; even men and womens wedding rings.
Another question; is the reason for the U.S. warring in the middle east because those countries want to sell their oil without using the petro dollar?
