Code Breakers and Spies of the War on Terror [PDF ebook] 

Shortly after the terrorist attacks on the World Trade Center and the Pentagon on September 11, 2001, the U.S. government began both a ground and aerial military campaign in the Middle East in order to preemptively rout out terrorists. During the War on Terror, the cause of the United States and its allies was aided by many technical innovations in code breaking and espionage. In fact, increased surveillance went so far as to spy on regular citizens. This book explores the evolution of intelligence technologies and how these new methods controversially shape wars, and the dilemma many militaries and governments face in deciding how to use them in order to avoid political fallout in the global age of terrorism.
