This is the textbook for the best and the brightest of both the academic world and the policy world. It is not an easy read, between the British language form and the deep thinking, but it is, as Christopher Andrew says, “the best overview” and “surely destined to become a standard work”. I especially liked its attention to components and boundaries, effects, accuracy, and evaluation. Perhaps most usefully within the book is the distinction between long-term intelligence endeavors that rely primarily on open sources and serve to improve state understanding and state behavior, and short-term espionage that tends to be intrusive and heighten the target state's feelings of vulnerability and hostility. No intelligence library is complete without this book–it provides a rock-solid foundation for serious thinking about the intelligence in the 21st Century.
