I'm not particularly fond of the Saudis as anyone who has actually read what I've said in this thread knows.
I have said in this thread that at this time they are helping us more than hurting us in "THE WAR ON TERROR" or TWAMI as Sandman would have it.
Now, yeah, they're pursuing and killing A-Q's as best they know how right now. Why? Because it has apparently dawned on the Elite that guys like Osama really don't like THEM either. I bet there's a little Royal Sweat running down some less than stable backbones. They're beginning to see that after A-Q runs the infidels out of the Saudi peninsula, the Royal family will be the next target.
And actually, I think they were moving against A-Q in a fairly lackadaisical manner for a while. As you know, there is dissension in the Royal Family about this very issue.
Now, how long ago did they start to do anything at all? I'd say 9/11. They have (most likely grudgingly) cooperated with our Treasury, CIA, FBI and NSA types since then. Wholehearted cooperation? Probably not at first, but as the danger to themselves becomes more apparent, they've been moving a little faster.
Prior to 9/11? They were dangerously close to the folks Bush said he'd go after. I'd agree with that.
But since then, they've helped out enough to stay one step ahead of the hangman. I think they're coming round now though through what used to be termed "enlightend self-interest".
