This article makes an excellent contribution to the understanding of the appeal that many Muslim have for the Empire created Islamic State, but it omits all of the history of the Anglo-American ruling classes' use of this medieval dynasty to sustain their dominance in the world.
I haven't the slightest doubt that that this regime would have been put away in the dustbin of history except for its usefulness to the current US-led Empire. The Saudi Arabian people would have long ago thrown out these barbaric rulers had not the directors of the Empire decided to use their oil to back our fading dollar after losing much our national treasure in the war crimes committed by the directors in southeast Asia in the 1960s and 1970s. In exchange, we, like gangsters of the 1930s, offered these head-chopping fanatics protection from such an inevitability.
If you don't know this important history, then I highly recommend that you read this piece for starters. Then if you want a more comprehensive history of how oil has played a dominate role in world history especially by various empire builders, I suggest you view the videos linked to in this article.
