Via Instapundit, Eric Scheie responds to Greenspan's opinion that the war is "largely about oil:"
The fact is, if the damned Saudis didn't have the vast oil wealth, if we heard of Wahhabism at all, it would only be because we'd read about the quaint little religion as we looked at pictures of obscure goat and camel herders in the pages of the National Geographic.
So yes, it's all about oil. Without the oil, no one would care about this sickening, oil-soaked religion, or the fringe ideology that goes with it. Without oil, there'd have been no incentive and no money to train the Saudi bastards who flew the planes into the Twin Towers and the Pentagon.
So ultimately it's all about oil. So what?
Does that mean we weren't attacked?
Silly Eric. We attacked ourselves. Duh.
