"A rising China, climate change, terrorism, a nuclear Iran, a turbulent Middle East, and a reckless North Korea present serious challenges to our national security. But the biggest threat to the United States comes not from abroad-but from within. Burgeoning deficit and debt, crumbling infrastructure, second class schools, and an outdated immigration system have resulted in a country less competitive and far more vulnerable than it should be. In Foreign Policy Begins at Home, Council on Foreign Relations President Richard N. Haass describes a twenty-first century in which power is widely diffused. Globalization, revolutionary technologies, and power shifts have created a "nonpolar" world of American primacy but not domination. Still, it is a relatively forgiving world, one with no great power rival. How long this strategic respite will last, though, depends entirely on whether the United States puts its own house in order. Haass outlines a process of Restoration that will ensure the United States has the resources it needs to lead the world, set examples other societies will want to emulate, reduce the country's vulnerability to hostile forces and fickle markets, and discourage would-be adversaries from mounting aggression. Provocative and bold, Foreign Policy Begins at Home lays out a new vision for American Restoration. It will require hard choices, but hard choices are called for. At stake is nothing less than America's future and the character of the coming era of history. "--

Spies, secret messages, and military intelligence have fascinated readers for centuries but never more than today, when terrorists threaten America and society depends so heavily on communications. Much of what was known about communications intelligence came first from David Kahn's pathbreaking book, The Codebreakers. Kahn, considered the dean of intelligence historians, is also the author of Hitler’s Spies: German Military Intelligence in World War II and Seizing the Enigma: The Race to Break the German U-Boat Codes, 1939-1943, among other books and articles. Kahn’s latest book, How I Discovered World War II's Greatest Spy and Other Stories of Intelligence and Code, provides insights into the dark realm of intelligence and code that will fascinate cryptologists, intelligence personnel, and the millions interested in military history, espionage, and global affairs. It opens with Kahn telling how he discovered the identity of the man who sold key information about Germany’s Enigma machine during World War II that enabled Polish and then British codebreakers to read secret messages. Next Kahn addresses the question often asked about Pearl Harbor: since we were breaking Japan’s codes, did President Roosevelt know that Japan was going to attack and let it happen to bring a reluctant nation into the war? Kahn looks into why Nazi Germany’s totalitarian intelligence was so poor, offers a theory of intelligence, explicates what Clausewitz said about intelligence, tells—on the basis of an interview with a head of Soviet codebreaking—something about Soviet Comint in the Cold War, and reveals how the Allies suppressed the second greatest secret of WWII. Providing an inside look into the efforts to gather and exploit intelligence during the past century, this book presents powerful ideas that can help guide present and future intelligence efforts. Though stories of WWII spying and codebreaking may seem worlds apart from social media security, computer viruses, and Internet surveillance, this book offers timeless lessons that may help today’s leaders avoid making the same mistakes that have helped bring at least one global power to its knees. The book includes a Foreword written by Bruce Schneier.
