An interesting title for a book. Over at the Counter Terrorism blog, they have a quick blurb about the book and a link to the full review. While I am not a counter-terrorism expert, nor do I play one on TV, this review has me interested enough to begin searching for the book. Perhaps you should also.
Kessler is on absolutely firm footing in describing the details of the various terrorist plots that have been disrupted by FBI spadework.
There is a lot more going on in the United States than you realize.
(I know I am wearing my paranoia hat way too much lately).
