"Such an event would destroy our complex, delicate high tech digital society in an instant and throw all our lives back to an existence equal to that of the Middle Ages," he wrote in an introduction to "One Second After," a 2009 science-fiction novel by William Forstchen.

They claim that terrorists aren't close to getting a nuclear weapon and that no country would dare try an EMP attack. But then few imagined a terror attack using airplanes against the twin towers or anthrax in letters.
