There's more discussion of this and related matters in a post on Moon of Alabama.
Did Bin Ladin come home to rule?
Briefly, due to this sudden resignation and a few other events mentioned in the post, there is suspicion of a rift between the US and Saudi Arabia and concern that something rather nasty may be in the works. Perhaps I'm being an alarmist but, ignorant as I am, when I heard about the Saudi clerics call for Sunni mobilization against the Shiites, I thought to myself, "Now that can't be good."
So does anyone have any wisdom or comfort (or both) to offer? Is something serious happening or am I just being a nervous nelly?
