I'm not beyond the idea that it is an inside job, humans are capable of some pretty sick stuff but then Again you can make a conspiracy for anything really.

If someone really wanted they could say it was Giant Lizards that orchestrated the events and they were in league with aliens in a big plot to send the U.S into War and make their foreign policy disliked so that nobody trusted anybody and the world would be easy pickings.

I'll stick with the official version of things.
