The Berlin Wall of the Internet

David Sanger, national security correspondent for The New York Times and the author of, now out in paperback, The Perfect Weapon: War, Sabotage, and Fear in the Cyber Age (Crown, 2018), talks about America's vulnerability to cyber attacks by global adversaries, including how the rise of China's Huawei could create two different — and opposing — cyber networks.

"Imagine a new Berlin Wall, but it’s built out of networks," says @SangerNYT. "One side of this wall is going to be the controlled internet, the internet you’ve seen in China that keeps Facebook and Google out, that monitors dissonance, the examination of facial recognition."
