In this provocative and thoughtful book, Amy Zegart challenges the conventional belief that national security agencies work reasonably well to serve the national interest as they were designed to do. Using a new institutionalist approach, Zegart asks what forces shaped the initial design of the Central Intelligence Agency, the Joint Chiefs of Staff, and the National Security Council in ways that meant they were handicapped from birth. Ironically, she finds that much of the blame can be ascribed to cherished features of American democracy frequent elections, the separation of powers, majority rule, political compromise all of which constrain presidential power and give Congress little incentive to create an effective foreign policy system. At the same time, bureaucrats in rival departments had the expertise, the staying power, and the incentives to sabotage the creation of effective competitors, and this is exactly what they did.
