Over decades and diverse administrations, justifications for the use of force - limited and full scale - have constantly revolved around weapons of mass destruction. Protection against them, real and imaginary, has served [as] justification for government excess and a curtailment of our freedoms. We stop everything because it is WMD and we fret about the consequences of both action and inaction because it is WMD. We do so because of a little known and little understood entity that truly drives American national security practices: It's called the Program. Founded in the darkest days of nuclear threat during the Eisenhower administration, the Program began as a limited system given responsibility for survival of the government. The nuclear arms race ended, but the Program never completely went away. And since 9/11, like everything else about national security, its mission and focus have expanded. The Program exists through a system of sealed envelopes - four dozen formal Presidential Emergency Action Documents more secret than anything that has been revealed about the National Security Agency of late, arrangements that instruct a surviving entity of what to do if a nation-destroying calamity befalls Washington or the United States. Because Doomsday is now thought by the experts in government to be any day, and because the potential battlefield is anyplace and every place, the work of the Program, and its power, have dramatically expanded. A survival apparatus operates behind the scenes as if survival is perpetually and instantly at stake.
