Extraordinary largely for showing contractors as the weak link ,
For those who have the patience or speed to get through this entire book, the single most important revelation and documentation concerns the ease with which the Russians were able to recruit traitors within the US defense community contractors. Ralph Peters has written about this in New Glory : Expanding America's Global Supremacy but speaks mostly of legal treason–corruption and waste. This book carefully addresses the sad reality that DoD is totally penetrated by foreign spies (one would add, Third World and allied spies including France, Germany, and Israel, never mind China and Iran) via the contracting community.
One day someone will do a careful calibration of both the good and the bad of secret intelligence. When that day comes, this book will be as good a place as any with which to start.
