The Legacy of Ashes: The History of the CIA by Tim Weiner[1] accuses the CIA of covert actions and human rights abuses. Jeffrey T. Richelson of the National Security Archive has been critical of its claims.[2] Intelligence expert David Wise faulted Weiner for portraying Allen Dulles as "a doddering old man" rather than the "shrewd professional spy" he knew and for refusing "to concede that the agency's leaders may have acted from patriotic motives or that the CIA ever did anything right," but concluded: "Legacy of Ashes succeeds as both journalism and history, and it is must reading for anyone interested in the CIA or American intelligence since World War II."[3] The CIA itself has responded to the claims made in Weiner's book, and has described it as "a 600-page op-ed piece masquerading as serious history."[4]
