On the one hand you seem to think they are clever and cunning, on the other hand they think they can stage a mass casualty attack on US soil (for what reason exactly?) without the US ever finding out and retaliating. I think the fact that no US government retaliated against Saudi Arabia for 9/11 is quite a bit of evidence in favor of there being no covered-up evidence that the Saudi Arabian government intentionally supported or even condoned this attack. Their dealings with the US in the past few decades tell me they know better than to poke the bear.
