Anne Applebaum has an interesting story about how the Saudi education authorities are inculcating hatred in children, and disseminating it as far and as wide as they can.
Now remember: there are no Israeli occupiers in Saudi Arabia. For that matter, there was never much of a European colonial domination of the area, either. You can hardly regard the Saudis as being part of an impoverished "South", can you. All in all, none of the standard templates for explaining away unpleasant non-Western behavior are much use when dealing with the Saudis. What you're left with is that they may simply believe in what they say, from choice, not necessity.
If you can live with that concept, the next thing will be to ask if there might be any connection between what the Saudis say and do, and what others in the Arab world say and do. Especially do.
