Well, sure, the Saudis have always been willing to be playmates with whomever might give them the best advantage/leverage, they'll play that game for as long as they can...for as long as the oil lasts or as long as their rule lasts...the former has an expiration date, the latter is more murky. There are huge questions over their royal succession and what it means for Saudi policy. As long as they have their rule, as long as they have their oil and as long as they have Mecca they will be at the center of everything going on in the region. I think the easiest way to destabilize them is through infiltration of the royal household and a decapitation of their leading patriarchs, a gambit their primary foes in Tehran are no doubt looking at, albeit their approach may be heavy-handed and easier to uncover, but others may try the same idea, and somebody more sophisticated or perhaps with outside (cough, Russia!) help could achieve it. And as we saw with AQ the Saudis have plenty of enemies within, a byproduct of Wahabi extremism, and now ISIS poses the same threat. Anyway, whatever happens, if they all kill each other off and Israel remains safe it's all good to me.
