This is a 50/50 book where half of it has aged well and the other half has not. It is also a 50/50 book in that you really only need to read half of it.
The first part of the book is "reports" from a source named Ali. I eventually skipped over much of this because they were vague and repetitive. Ali pretty much wrote variations of the same thing over and over. Weldon would have been better off using them throughout the book to support points he was trying to make rather than just making them half the book.
The second half of the book, Weldon does bring up many interesting and valid points of how the intelligence community was operating at the time. The mistakes and just out right incompetence was pretty remarkable, but not surprising, to read about.
Weldon does layout a pretty good idea for how the intelligence community should be reformed to get actual usable results. Unfortunately, however, much of the book comes across as him whining about why is no one listening to me.
