"This document attempts to explain why intelligence reform proposals recur so often, why they occasionally succeed, and why they often produce little change. In a sense this monograph traces the history of the position of the Director of Central Intelligence. It begins with the challenges faced by the Truman administration and Congress when they struck the basic compromises that created the post of DCI, follows the evolution of the vision of centrally coordinated intelligence, and suggests why so many people at both ends of Pennsylvania Avenue felt in 2004 that a new system was needed. The debates have by no means ended with the passage of new legislation supplanting the DCI with a Director of National Intelligence. The issues that have been in play since 1946"and have been analyzed by virtually every survey of the intelligence establishment since then"will remain live ones for the foreseeable future. This study, by clarifying the past, may help inform discussions of how US intelligence can change to meet new challenges at a time when good intelligence has rarely been so important for our nations future."
