My take: He's dumb as a fence post and not up to planning anything major but was a willing participant in the War on Other Countries that Have Things we Want. As for 9/11, it seems clear he knew and went along with it but I suspect it wasn't his idea and that he was uncomfortable with it. Might have been outright threatened to comply with that one, but he really leaned into the coverup.
