A newly drafted United States nuclear strategy that has been sent to President Trump for approval would permit the use of nuclear weapons to respond to a wide range of devastating but non-nuclear attacks on American infrastructure, including what current and former government officials described as the most crippling kind of cyberattacks.

David Sanger, senior fellow at the Belfer Center and adjunct lecturer in public policy at Harvard Kennedy School, was interviewed on NPR’s “On Point” about his new book on President Obama’s foreign policy efforts, including a cybercampaign against Iran’s nuclear program. Sanger’s book, Confront and Conceal: Obama’s Secret Wars and Surprising Use of American Power, was published this week.
