 This is On Point. I'm Deborah Becker. Stephen Sestanovich is with us. He's Senior Fellow at the Council on Foreign Relations, and he was a U.S. Ambassador-at-Large for the former Soviet Union from 1997 to 2001. Also with us is Sung Yoon Lee, a fellow at the Woodrow Wilson International Center for Scholars, and we're talking about this agreement between Russia and North Korea.
