David Talbot's 'The Devil's Chessboard' is a critical biography of Allen Dulles, who as CIA director transformed American intelligence into an instrument for overthrowing governments, eliminating foreign leaders, and pursuing Cold War objectives beyond democratic accountability. Talbot draws on declassified documents, interviews, and archival research to portray Dulles as the architect of a secret government within the government, whose operations from Iran to Guatemala to Cuba shaped the modern world while remaining hidden from public view. The book traces Dulles from his Wall Street legal career, where his firm represented Nazi industrial interests, through his rise to CIA leadership and the disastrous Bay of Pigs invasion that led Kennedy to fire him. Talbot is particularly interested in Dulles's activities after his dismissal, suggesting his continued influence over covert operations and intelligence networks. The book's treatment of the Kennedy assassination will be controversial; Talbot clearly finds the Warren Commission investigation, on which Dulles served, inadequate. Readers should approach the more speculative arguments critically, but the documented record of CIA activities under Dulles is damning enough. Those interested in Cold War history, intelligence agencies, or the limits of democratic oversight will find disturbing material.
