|"Non-fiction" hmm... The author Thierry Meyssan's main claim is that there was no plane crash at the Pentagon on 9/11: that the "crash" was faked by unnamed American secret services which used a truck bomb to cause minor damage. The book sold over 100,000 copies in France but I don't think any English translation was published. You'll find a summary w further links here and commentary with pix here -- Pentagon wasn't destroyed, no plane parts are visible in photos, ergo no plane crash, right?
I reckon Meyssan was just out to make himself a bundle of money. That his "theory" could be taken seriously over there suggests either mass gullibility or severe paranoia about the Pentagon. Or both.
Ah! This same book contains the low-down on the bush wwii connection? It does sound fanciful--a collection of badass paranoid rumors about Ugly Americanism.
