If I were one of those crazy conspiracy nuts, I might think something like this: The attacks on the World Trade Center and the Pentagon were carried out by the CIA, in collusion with the President and his "advisors", in order to bring about an inter-related set of objectives:
The President needs a convincing excuse to invade Afghanistan, or some other oil-rich Middle Eastern country, in order to get his hands on foreign reserves without having to answer to OPEC. Of course, Big Oil would love to do some drilling in ANWR or off the Florida coast, but environmentalists have been squawking too loudly. This has damaged the President
