This book is the sequel to ON INTELLIGENCE: Spies and Secrecy in an Open World (AFCEA International Press, 2000). That book, written largely for government and corporate intelligence professionals, remains the basic reference volume for the future of global intelligence enterprises. This book, by contrast, is a completely new effort that is written for every citizen of every countrythe "intelligence minutemen" of the 21st Century. In the aftermath of the 11 September 2001 attacks on the World Trade Center and the Pentagon, attacks carried out by a non-state actor skilled at asymmetric warfare and using our own capabilities against usattacks followed quickly by a nation-wide anthrax assault that closed Congress and terrified the U.S. Postal Serviceit is imperative that every citizen have a clear-headed understanding of what is at stake and what needs to be done to keep not only America, but all civilized communities safe. It is especially imperative that citizens understand that the world is already at war, with millions of refugees in 67 countries, plagues sweeping across 59 countries, mass starvation in 27 countries, and deliberate genocide campaigns in 18 countries. These are "facts of life" that our schools, our media and even our intelligence communities have been unwilling and unable to represent intelligently to the public. It is against this backdrop of global chaos that terrorism rises.
