BTW, the 9-11 attacks were wildly celebrated within Saudi Arabia. People were high-fiving each other. The KSA should have received about a dozen nukes on after 9-11. Instead we get George Bush Junior tongue kissing the old pervert Saudi King, followed by Obama bowing to him.
And those members of the Saudi royals were killed. I don't doubt that that the Saudi populace celebrated 9/11. These are the Saudi subjects bin Laden was counting on to overthrow the royals and put him in charge. Bin Laden was a king-in-waiting waiting for his main chance and throwing various things at the wall (including the Cole bombing and 9/11) to help things along.
We had better hope the Saudi royal family holds up. The alternative, a Saudi Arabia (renamed something else to remove its association with the al Saud family) ruled by al Qaeda with universal popular support is unthinkable. It would be ISIS with the world's largest oil reserves.
