Self-preservation, as defined by the house of Saud:

It is a mistake to think that our people will not do what is necessary to survive and if that means we move to the right of bin Laden, so be it; to the left of Qaddafi, so be it; or fly to Baghdad and embrace Saddam like a brother, so be it. It’s damned lonely in our part of the world, and we can no longer defend our relationship [with America] to our people.
