RealClear Cyber Today host Andrew Walworth discusses the future of cyber conflict and the quickly evolving world of cyber strategy with New York Times National Security Correspondent David Sanger, author of the new book The Perfect Weapon: War, Sabotage and Fear in the Cyber Age. In an era marked by increasingly aggressive use of cyber weapons by a range of adversaries, US policymakers have been slow to develop a coherent strategy for their use, even as America deploys its own cyber arsenal against foreign targets. In an in-depth interview, Sanger discusses how the US is already both an aggressor and defender in a multitude of cyber conflicts, and why it is vital that American policymakers develop strategies and norms regarding cyber weapons and their use.
