One estimate projects that 5G will pump twelve trillion dollars into the global economy by 2035, and add twenty-two million new jobs in the United States alone. The claims are extravagant, and the stakes are high. Remote robotic surgery will be routine, the military will develop hypersonic weapons, and autonomous vehicles will cruise safely along smart highways. This, again, if you believe the hype, will lead to a whole new Internet of Things, where everything from toasters to dog collars to dialysis pumps to running shoes will be connected.

Two words explain the difference between our current wireless networks and 5G: speed and latency. “It was about the physics, about what was possible.” To Spalding’s surprise, the Axios story was based on a leaked early draft of a report he’d been working on for the better part of a year. “I wasn’t looking at this from a policy perspective,” he said. At the N.S.C., he was studying ways to insure that the next generation of Internet connectivity, what is commonly referred to as 5G, can be made secure from cyberattacks. “Scoop,” the headline read, “Trump Team Considers Nationalizing 5G Network.” At the time, Spalding, a brigadier general in the Air Force who previously served as a defense attaché in Beijing, had been in the military for nearly three decades. In January, 2018, Robert Spalding, the senior director for strategic planning at the National Security Council, was in his office at the Eisenhower Executive Office Building, across the street from the White House, when he saw a breaking-news alert on the Axios Web site.
