The problem in Saudi right now is that the rulers are on the brink of being overthrown by OBL types. Be careful what you wish for.
The insane Wahabbists are a disease that Saudis themselves have bred (through their anti-Israel and anti-American "educational" cirricula). As you probably know, they had little choice in the matter if they wanted to stay in power. If there's no external enemy for their Jihadist populace to obsess over, they'd inevitably turn their attention to their own leaders, and the fact the .00001% live in obsene luxury while the rest live in abject poverty. Concocting a "Great Satan" was the House of Saud's survival mechanism, nothing more.
So, my view is that the longer we wait to destroy the Saudis, the more dangerous the Jihadist beast will become. My prediction: This fall, Iraq. Next fall, Saudi Arabia.
This used to be a concern to me as well, but I no longer consider it. We can't be hesitant to eliminate evil because we are afraid more (and possibly greater) evil will replace it. If the house of Saud is thrown out and an even more anti-American regime takes over, so be it.
It could actually help the situation by making the picture clearer for everyone..
