Conspiracy theorists simply go too far and end up killing legitimate debate. I do firmly believe the US govt DID deliberately bring about 9-11 but it had nothing to do with cruise missiles and hidden explosives. I simply believe that agents had infiltrated al-Qaeda and pushed for the idea of hijacking planes and flying them into the WTC. But that's the extent of it. Why would they need to go beyond that? That would be enough to frighten the public like the scared little sheep they are and let the idiot they put in the White House do any goddamn thing he wants to.
