‘The Blinding Future of Nuclear Weapons’ with Journalist Sarah Scoles

The United States is in the middle of a massive modernization effort of its nuclear weapons, as tensions rise globally, from Russia’s invasion of Ukraine to expanding arsenals in China and North Korea. Journalist Sarah Scoles set out to understand the U.S.’s biggest reinvestment in its atomic infrastructure in decades by talking with the people who work on them daily, scientists at nuclear labs. In the process, as she documents in her new book “Countdown,” she interrogates our need for these weapons and their impact on war — and peace. She joins us to share more about the science, technology and philosophy of nuclear weaponry.
