The world had changed in the thirty-odd years since Gunman. It was no longer the case that Americans used one set of typewriters, while our adversaries used another. Thanks to globalization, we now all relied on the same technology. A zero-day exploit in the NSA’s arsenal could not be tailored to affect only a Pakistani intelligence official or an al-Qaeda operative. American citizens, businesses, and critical infrastructure would also be vulnerable if that zero-day were to come into the hands of a foreign power, cybercriminal, or rogue hacker.
