In a review of Pacepa's book published in Human Events, Michael Ledeen, former adviser for terrorism to President Ronald Reagan, writes: "A new book from General Ion Mihai Pacepa is cause for celebration, because he is among a tiny handful of people who know a lot about the intelligence services of the Soviet Empire, and because he writes about it with rare lucidity, always with an eye to helping us understand our world. His first book, 'Red Horizons,' is indubitably the most brilliant portrait of a Communist regime I've ever read. 'Programmed to Kill' is equally fascinating. Pacepa painstakingly takes us through the documentary evidence, including invaluable material on Soviet bloc cyphers that throws new light on Oswald's letters to KGB officers in Washington and Mexico City. … No novelist could have written a more exciting story, made all the more compelling because of Pacepa's first-hand involvement in the Russians' efforts to hide their Oswald connection." In "H-Net Reviews", Stan Weeber called "Programmed to Kill" "a superb new paradigmatic work on the death of President Kennedy" and "a 'must read' for everyone interested in the assassination of President Kennedy."
