There is a quite interesting article at The Independent by laureated English journalist Robert Fisk, which is being reproduced once and again through the Internet because it touches a central issue of the Arab Revolution: Saudi Arabia.
Saudi Arabia is the most totalitarian dictatorship in the whole World without doubt. Worse: it is a most obsolete kind of dictatorship: hereditary absolute theocratic patriarchal misogynist polygynous monarchy, which has imposed a state of Islamist terror since the early 19th century, not only in its own territory but all around as much as possible: Pakistan, Al Qaeda, the Algerian Islamist terror... all are product of Saudi machinations, let's face it.
But, the same that the USA (and with it all NATO) bow before the economic and power-mongering might of Israel, they also bow to Saudi Arabia. In fact, the Washington-Tel Aviv-Riyadh triangle is the core alliance, not always explicit, of the so-called Middle East: an imperialist alliance against democracy and secularism in the Arab World and other areas of Muslim tradition.
