I do not understand your point.
The Saudi "royal" family is a very large tribal affair - more like the 1500-1800 Sultans of the Ottoman Empire - There are many factions looking to get wealthier and impose extremist Wahhabi dictatorship.
The latest prince who is currently ruling the "kingdom" has "stolen" a bunch of money from some of these corrupt "family" members AND he is "liberating" women and/or bringing the "kingdom" to the 20th century.
Iran/Persia has a different history as well as a different religious sect. Iran being ruled by Muslim dictators, whom Obama supported, is undergoing an internal revolution.
And they should have been blown to hell on Sept 12th.
