It's tinfoily for sure, but this notion goes a long way toward explaining why the GWB was satisfied to have his head kicked in by the "Bush Lied / People Died" crowd rather than verify it's veracity. Whether or not it was us directly of through third parties, it would be a horror show.
I'm not sure we'll ever know one way or another and the powers-that-be are happy to have it be so.
you forget the Bush 1 was in charge of the CIA when all this started..kinda like Bush 2 covering for the dad!
