Richard Clarke's book is an authoritative insight into the machinations of the US political system. It documents 20 years of work within the White House covering counter-terrorism activities, under Presidents Reagan, Bush the elder, Clinton and Bush the younger. Although the book is one man's recollection, it appears complete and comprehensive, especially when discussing policy issues, decision-making (or lack of it) and politico-military options relating to, and contributing to, world events.
Where Clarke's book becomes really interesting, even more so than the recording of history, is when comparing various Presidents' style. As someone who strongly disagrees with virtually all government actions, it was valuable to gain insight to the processes, or lack thereof, used by the various Presidents.
I can understand why the current White House is concerned with this critical book, from a credible and authoritative source. It really discredits many of the actions of Bush, Rice, Cheney, Rumsfeld, Wolfowitz and Ashcroft, as well as the FBI, CIA and even Joint Chiefs of Staff. Few in the Bush administration come out of this with their credibility intact, only Colin Powell appears to have any understanding of the geopolitical consequences of action and inaction based on imprecise, dogmatic ideology, rather than a holistic view of the complexities in the real world. Unfortunately he appears to have been browbeaten by the inflexible ideologues in the Bush administration. Rather surprisingly ex-President Clinton is demonstrated to be a deep thinker who revels in the complexities of geopolitical analysis, often to the chagrin of his analysts.
This text should be mandatory reading for anyone with a vote in the forthcoming US Presidential election (and the UK General Election as this indicates what Blair was allying himself and the UK to).
If you are at all interested in the on-going geopolitical crisis then read this book (and "Holy War, Inc.")!
