As U. S. Secretary of State Rex Tillerson begins a trip to Asia this week, the emerging nuclear threat posed by North Korea will likely be a major subject of his talks in Japan, South Korea, and China.
However, Russia remains the U.S. adversary with the largest nuclear capability by far, and the chance of a conflict with Russia--especially one caused by lack of communication--continues to worry former U.S. Senator Sam Nunn.
The Georgia Democrat is a former chairman of the Senate Armed Services Committee, and is currently the co-chair and CEO of the Nuclear Threat Initiative. Recently, he introduced Tillerson at the Senate confirmation hearings for Secretary of State.
In part 2 of a conversation with Denis O'Hayer on Morning Edition, Nunn talked about how President Trump's push for warmer relations with Russia--and his own relationship with Russian leader Vladimir Putin--might affect the nuclear weapons equation. (Here's a link to listen to Part 1.)
(Note: The expanded version also includes Sen. Nunn's thoughts on the President's proposal for big increases in U.S. defense spending, and his stated goal of tearing up the nuclear deal with Iran.)
