This idea had been in the back of my mind for some time. What was the absolute worst threat Iraq could make against America? Missiles with nuclear or biological warheads? No, they didn't have those. Additional terrorist attacks? No. The worst weapon was the threat to quit denominating oil in dollars and switch to Euro's and to persuade other oil producers to do the same. This would literally bring down our economy and not only would we no longer be the supreme economic and military power in the world we would drop like Great Britain did after WWII when they relinquished that role to us. I knew this was a terrible threat. I didn't know that Iraq under Hussain had actually started doing this. That's what this video on Utube says and that's why we invaded Iraq. http://www.videosift.com/video/Why-th-US-UK-are-in-Iraq-explained-in-8-minsI-knew-it I'm going to try to substantiate this theory further but I find it to be very believable. The video goes on to say that Iran has similar but even more devastating objectives along the same lines.
