Muhammad ibn ʿAbd al-Wahhab (the founder of Wahhabism) BEIRUT -- The dramatic arrival of Da'ish (ISIS) on the stage of Iraq has shocked many in the West. Many have been perplexed -- and horrified -- by its violence and its evident magnetism for Sunni youth. But more than this, they find Saudi Arabia's ambivalence in the face of this manifestation both troubling and inexplicable, wondering, "Don't the Saudis understand that ISIS threatens them, too?" It appears -- even now -- that Saudi Arabia's ruling elite is divided. Some applaud that ISIS is fighting Iranian Shiite "fire" with Sunni "fire"; that a new Sunni state is taking shape at the very heart of what they regard as a historical Sunni patrimony; and they are drawn by Da'ish's strict Salafist ideology. Other Saudis are more fearful, and recall the history of the revolt against Abd-al Aziz by the Wahhabist Ikhwan (Disclaimer: this Ikhwan has nothing to do with the Muslim Brotherhood Ikhwan -- please note, all further references hereafter are to the Wahhabist Ikhwan, and not to the Muslim Brotherhood Ikhwan), but which nearly imploded Wahhabism and the al-Saud in the late 1920s. Many Saudis are deeply disturbed by the radical doctrines of Da'ish (ISIS) -- and are beginning to question some aspects of Saudi Arabia's direction and discourse.
