Books like The SIGINT secrets by Nigel West

A definitive, document‑rich history of the CIA, revealing why presidents and CIA leaders have struggled to grasp global realities and how repeated failures have threatened U.S. national security.

The book the NSA tried to suppress -- with a startling new afterword on the Geoffrey Arthur Prime spy case. The National Security Agency is the largest, most secretive, and potentially most intrusive American intelligence agency. It dwarfs the CIA in budget, manpower, and influence. In the three decades it has existed, the NSA has demonstrated a shocking disregard for the law. Until now, the inner workings of this agency have eluded public scrutiny. In this remarkable tour de force of investigative reporting, however, James Bamford penetrates the NSA's vast network of power -- the acres of computers, the electronic listening posts worldwide, the intelligence-gathering satellites, and the people who control them. The Puzzle Palace is a brilliant account of the use and abuse of technological espionage and of the frightening Orwellian potential of today's intelligence communites. - Back cover.
