I thought this article was very interesting (not that I agreed with all of it) explaining the very complicated relationship between Washington DC and Riyadh. There is always the risk of oversimplifying the relationship but I think this article does a good job of avoiding that trap. It also explains the somewhat fraught relationship between Iran and the Gulf States. Such is the complications of the relationship between the Gulf States and Iran, even my friend (who has always kept his counsel on the subject of Iran) talked about the "mad country next door that may do something at any time". Whether this is true or not, probably doesn't matter as long as people believe it will happen.
