Last week I read in Arab News that the Saudis were sending an 83 person delegation to the conference in New York to embark on a "charm offensive". I guess they got here and realized how uncharmed by them we are. Funny how the Saudis seem to have this Marie Antoinette pampered rich cluelessness about how real people in the real world think. They are simply spoiled.
Saudis act the way people do who are accustomed to despotic, clannish rule. They think everything is conspiratorial and if they bribe the right people (i.e., Neil Bush) anything can be fixed. The notion that we have a legitimate beef with them, with their two faced funding of religious extremism.
You couldn't expect them to act any differently, after all their news sources are CNN and the big three. They see the media treating their own populace in this fashion and merely emulate them.
