is an attempt to find shadowy secret reasons and motivations BEHIND the obvious.
In this case no theory is needed. The hijackers were Saudi. Their leader was Saudi. Assuming that the hijacking was a Saudi operation is simple and Ockhamy and direct and obvious.
Birdshit is a bird operation. A head-on crash is an automobile operation. Pearl Harbor was a Jap operation. 9/11 was a Saudi operation.
Saudis did it. You can't get any more non-shadowy and non-secret than that.
Any other assumption is a conspiracy theory. Some of those theories are partly right because the evidence, though incomplete, is obvious. CIA likely had some involvement in 9/11 because CIA was running Sheikh Osama, and because there's no evidence that Osama stopped being a CIA agent. Other theories such as Afghan or Iraqi involvement have exactly zero supporting evidence.
Our misgovernment was using clearly false conspiracy theories when it made war against Afghanistan and Iraq in response to the Saudi attack.
