Freon Sandoz got it right. By comparison with the Medieval kingdom of Saud, Iran has 600 Christian churches, Saudi Arabia none. Christianity is banned. If you travel in Teheran you have a very good chance of being picked up by a lady taxi driver. In SA, women are not allowed to drive. What makes the difference? SA is SUNNI and adheres to the most violent and intolerant sect in the world, ie, Wahhabism, the one that EVERY member of the Taliban, Al-Qaeda and ISIS belongs to. Iran is SHIITE and opposes these monsters, The myth that Iran is the "biggest state sponsor of terror" is therefore  a lie pushed by the Saudis and their vassals in Wahington. Why does the US bow to SA? Because of the petrodollar agreement by which the US uses its military to support Saudi terror in exchange for the Saudis propping up the dollar by allowing payment for oil only in USD. The problem with all this skullduggery? The Saudis are about to go bust. Visit:  newsilkstrategies.com for details.
