You have to keep in mind a carefully researched book that showed there was NO direct Bin Laden-China leak wouldn't sell. But one that does will sell thousands to the foil hatters.
I have to state I'm NOT pro-PRC, and nor do I believe the PRC is no threat to the US...it is. But there is just an amazing amount of BS out there overhyping China's military, claiming hundreds of thousands of PRC troops are all over the world, and the new hobby horse is linking China to Al Qaeda directly.
Without a copy of the book it's difficult to analyze it line-by-line. But I'm 95% sure it's pure BS. Nothing about the author gives me any confidence at all it's a rational, balanced analysis.
