By 2004 he was wrapping up his 9/11 arguments, dropping the issue as dead, "Rubicon" I guess being the obituary. He was moving on to a broader program to prepare the world for the post-Oil Peak crash. In his master 9/11 opus and parting shot Crossing the Rubicon, Ruppert took the isue head-on. He stated “I have never believed Flight 77 hit the Pentagon,” and further described the attack craft, much like IPS and Loose Change might, as:
“the miracle plane. The one that nobody actually saw hit the Pentagon; the one that left no recognizable debris matching an airliner; the one [Thierry Meyssan] did a pretty convincing job of proving never hit the Pentagon because the hole was way too small and the damage pattern […] was totally inconsistent with a mid-sized passenger jet like a 757; the one where the engines melted, disappeared or evaporated, or were transported into space by the Starship Enterprise and never found; the one that flew like a fighter plane or a cruise missile.” 
He showed a certain change of heart, describing the analysis of physical evidence like Meyssan’s as “a key forensic technique used by police officers.” Of course Meyssan was “crucified in the American press,” and it was this Frenchman flogging, not the fear of being wrong (as Meyssan seems to be), that gave Ruppert his lesson “about what happens in America when one tries to make a conspiracy case in the public arena, based solely on physical evidence.” 
So despite his earlier caution, even Ruppert isn’t really with me on this case. Even as he has tired of “what happens in America” and fled to Caracas and the protective embrace of Hugo Chavez, on his way out the door he let us know the frustrating fraud has its tentacles everywhere, even superceding his finely honed “cop instincts.” How did it get to this point, and where does it go next?
