The issue of the Saudi government is a tough one. I can't really fault the Bush Administration's position too greatly, as a push for democracy would very likely lead to something far worse. But it's important to understand what we mean when we refer to the Saudi "government" which is composed of one giant family, and I mean that literally - the House of Saad. I have no doubt that those at the highest levels of power want bin Laden as bad or worse than we do, as he is truly an existential threat to them. But there are plenty of family members that also finance AQ and provide them intel. So it's not an easy situation.
My limited objection the Bush Administration's policy is based upon my two favorite lawmakers - Bob Graham and Jim Davis. Graham believes, and he can explain it persuasively, that we well should have pushed the Saudis after 9/11 and held them responsible, not with invasion but directly stating that they harbor AQ supporters, which they do. It's not like those at the top don't know they have core AQ supporters at the family reunion, but they feel they are powerless to purge them. Graham thinks that must be pressed, accepting the risk, because AQ will never be completely defeated so long as they have the Saudi support, which dwarfs all other support, financially and otherwise.
Also, Jim Davis, now a candidate for governor, has pressed us to try to compel educational reformed over there, which is also potentially destabilizing. But the House of Saad made a deal with the devil with the Wahabbists, giving them control of the ediucational system in exchange for political support for the House of Saad to rule. Jim feels that until that is broken, the Saudi system will still turn out jihadists on a regular basis despite the alliance with the leaders at the top. In both cases, it is a matter of accepting the inevitable and dealing with it now to avoid a sudden fall like Iran in 1979
