The Way of the Knife: The CIA, a Secret Army, and a War at the Ends of the Earth. By Mark Mazzetti (2014)

This book is a hodgepodge of stories about CIA and JSOC operations, and the associated interagency friction/competition. He spends a lot of time condemning the CIA's use of drones, and in true western reporting fashion focuses the bulk of his comments on so-called collateral damage and very little time on the number of terrorist attacks prevented. The media should hold us accountable, we made numerous tragic errors, but there have also been numerous successes at the tactical level. As the author readily admits, when you're dealing with mostly confidential sources providing information that frequently can't be validated or dual sourced, there will be a degree of error in reporting.

If the author is trying to make an overall point, it is that our national security structure was turned upside down after 9/11. In his view the CIA assumed the role of the military, and military SOF assumed the role of the CIA (intelligence collection). In my view, he overstates this since the CIA has always been involved to various degrees in paramilitary operations and the military has always done intelligence operations. Clearly the type and scale of intelligence operations and paramilitary operations have changed since 9/11 based on the threat.

The book is a quick read, and the inside stories on Yemen and Pakistan probably make the book worth reading with the caveat that it is written with a high degree of bias.
