The Carnegie

The global nuclear order is facing unprecedented challenges with Russia, North Korea and Iran all testing the limits of nuclear non-proliferation. The landmark Nuclear Non-Proliferation Treaty marks its 50th anniversary next year. Will it be able to survive in its present form? This month, as Carnegie brings together 800 experts for its nuclear policy conference in Washington, Tom Carver spoke with Carnegie’s James Acton and Toby Dalton about the nuclear nonproliferation agenda.

The Carnegie Podcast is a regular series hosted by Tom Carver featuring commentary and analysis from Carnegie experts on critical global issues.
