It wasn’t long ago that both heads of state and prominent policymakers could speak seriously about a world without nuclear weapons. But in the course of just a few years, nuclear concerns have come back in force. Arms control has broken down almost entirely. China has started a massive expansion of its arsenal, putting basic assumptions about deterrence in doubt. Vladimir Putin has threatened nuclear use in Ukraine—threats that were taken very seriously by American officials. And proliferation risks have grown, with regard to both American adversaries like Iran and American allies in Europe and Asia who may no longer trust security commitments from the United States.
Vipin Narang and Pranay Vaddi until recently oversaw nuclear policy in the Pentagon and on the National Security Council. In a new essay for Foreign Affairs, they call the situation nothing short of a “Category 5 hurricane.” And for the United States, that means putting nuclear strategy back at the center of foreign policy.
Editor-at-large Hugh Eakin spoke with Narang and Vaddi about this changing nuclear landscape and what the United States must do to survive this new nuclear age.
