>I dropped my jaw out of suprise, when I heard US going to declare war on Iraq — Saudis' biggest enemy.
You're being more than a little disingenuous ignoring the fact that we invaded Afghanistan specifically to go after the extremist group that was responsible for 9/11 about 2yr prior to invading Iraq, which was done for different reasons and "harboring terrorists" took a back seat to WMDs on that list of reasons.
The attack in Afghanistan was initially to attack Al Quada directly. It turned into a war against the Taliban when they refused to give him up. That went on for a year or so, but the drum beat of war against Iraq started on 9/12.
There is a memo from Rumsfeld around then. [1]
The fact that all the terrorists were Saudi, that Bin Laden was Saudi, that Iraq was an enemy of the Saud regime, that Iraq was a "buffer" between the rest of the Middle East and Iran, all of that was ignored.
The war in Iraq was the US worst foreign affairs decision in the last 50 years.
All of the "WMD" and then "bringing democracy" was retconning the original desire to finish the first Iraq war, which had nothing to do with 9/11.
That doesn't change his main point. Saudi Arabia was one of the primary financiers of the taliban and Al Qaida, but instead of going after the Saudis some of the only non military flights to be allowed to fly just after 9/11 were private jets that flew Saudi Royal family members out of the country.
