Executive Secrets [PDF ebook] 
Covert Action and the Presidency

A frank and refreshing evaluation of several Chief Executives, their Directors of Central Intelligence, and even some lower in the hierarchy, Executive Secrets shines light on the development and execution of foreign policy through the understanding of the tools available, of which covert action may be least known and understood. This book is a great tool for the press, the public, and many political appointees in the National Security System. A History Book Club Selection with a foreword by Mark Bowden, author of Black Hawk Down.
