John R. Schindler is professor of national security affairs at the U.S. Naval War College, where he’s been since 2005, and where he teaches courses on security, strategy, intelligence, terrorism, and occasionally military history. Before joining the NWC faculty, he spent nearly a decade with the National Security Agency as an intelligence analyst and counterintelligence officer. There’s not much he can say about that, except that he worked problems in Eastern Europe and the Middle East with a counterespionage flavor, and he collaborated closely with other government agencies who would probably prefer he didn’t mention them. He’s also served as an officer specializing in cryptology (now called information warfare for no particular reason) in the U.S. Navy Reserve.
