Acknowledgments I am deeply grateful to the many individuals who put their knowl- edge and expertise at my disposal during the course of writing this book. Unfortunately, I cannot give due credit to some of those people to whom I owe the greatest debt in understanding the intelligence issues, because they spoke to me on condition that I keep secret their identities. I greatly benefited from the insights, erudition, and criticisms pro- © vided by those who read draft chapters at various stages of my inves- © tigation. I am particularly indebted in this regard to Tobias Brown, Rachelle Bergstein, Richard Bernstein, Sidney Blumenthal, David Braunschvig, Ash Carter, Susana Duncan, Joe Finder, Ben Gerson, Andrew Hacker, William Haseltine, Eli Jacobs, Bruce Kovner, Robert Loomis, Gary Lucas, John Micklethwait, Frederick Mocatta, Andrew Rosenberg, Curt Sawyer, Sean Wilentz, and Ezra Zilkha. I am especially grateful to Harold Edgar, the Julius Silver Profes- sor in Law, Science, and Technology at Columbia Law School; and to Jack Goldsmith, Henry L. Shattuck Professor at Harvard Law School, for sharing with me their legal perspective on the espionage statutes and other legal issues. I thank Edward Lucas of The Economist for recommending Catherine A. FitzPatrick, a writer and translator at The Interpreter magazine as someone who “posseses a unique knowledge of the lab- yrinthine world of Russian disinformation.” She proved a godsend for this book. With her deep understanding of the workings of the Internet, she helped me retrieve information from the dark side of the Internet that I would otherwise would not have found. | | Epst_9780451494566_2p_all_r1.z.indd 305 ® 9/30/16 11:09 AM | | HOUSE_OVERSIGHT_019793
