While we're obsessed with protecting our physical borders... we left the digital border wide open. If Russia or China tried to fly a plane into the United States, our Pentagon and billions of dollars of defense infrastructure... will shoot that thing down ... If they try to come into the country, they'll get stopped by the passport control system ... If Russia or China try to fly an information bomb into the country, instead of being met by the Department of Defense, they're met by a Facebook algorithm with a white glove that says 'Exactly which zip code do you want to target?'
