In recent years the importance of Signals Intelligence (Sigint) has become more prominent, especially the capabilities and possibilities of reading and deciphering diplomatic, military and commercial communications of other nations. This growing awareness of the importance of intelligence applies not only to the activities of the big services but also to those smaller nations like The Netherlands. For this reason The Netherlands Intelligence Association (NISA) was recently established in which academics and (former and still active) members of The Netherlands intelligence community work together in order to promote research into the history of Dutch intelligence communities.--

In Code Warriors, Stephen Budiansky--a longtime expert in cryptology--tells the fascinating story of how NSA came to be, from its roots in World War II through the fall of the Berlin Wall. Along the way, he guides us through the fascinating challenges faced by cryptanalysts, and how they broke some of the most complicated codes of the twentieth century. With access to new documents, Budiansky shows where the agency succeeded and failed during the Cold War, but his account also offers crucial perspective for assessing NSA today in the wake of the Edward Snowden revelations. Budiansky shows how NSA's obsession with recording every bit of data and decoding every signal is far from a new development; throughout its history the depth and breadth of the agency's reach has resulted in both remarkable successes and destructive failures.

At the dawn of the Cold War, the world’s most important intelligence agencies—the Soviet KGB, the American CIA, and the British MI6—appeared to have clear-cut roles and a sense of rising importance in their respective countries. But when Kim Philby, head of MI6’s Russian division and arguably the twenty-first century’s greatest spy, was revealed to be a Russian mole along with British government heavyweights Donald Maclean and Guy Burgess, everything in the Western intelligence world turned upside down. Here is the true story of how the American James Bond—the colorful, foulmouthed, pistol-packing, alcoholic ex-FBI agent William “King” Harvey—put the finger on Philby; how James Jesus Angleton, the chain-smoking poet of Yale University and the CIA’s supposed “master spy” in charge of counterintelligence, began his descent into a paranoid wilderness of mirrors upon learning of family friend Kim Philby’s ultimate betrayal; and the devastating consequences of the loss of MI6 prestige and the CIA’s subsequent self-defeating witch hunts. Every revelation, every stranger-than-fiction twist and turn is all the more intriguing as truths become lies and unlikely scenarios are revealed as reality. With impeccable sourcing and the use of thousands of pages of declassified research, David C. Martin’s Wilderness of Mirrors is widely recognized as a masterpiece of intelligence literature.
