Tomorrow @ Noon ET - Extending New START and Revitalizing Great Power Nuclear Cooperation

New Strategic Arms Reduction Treaty (START), the last standing bilateral nuclear arms control agreement between the United States and Russia, expires tomorrow. With New START’s end and absent any successor agreement, remaining guardrails on nuclear weapons proliferation would lapse and pave the way for an unrestrained nuclear arms race between the United States, Russia, and China. What is the likely road ahead, and how do we approach the pragmatic imperative of preventing an expensive and destabilizing nuclear arms race?
