What will it take for North Korea to release Merrill Newman and Kenneth Bae?

Two Americans are living a cold war nightmare right now inside North Korea. More than a month ago, 85-year-old Korean War veteran Merrill Newman was dragged off his flight home from Pyongyang and arrested. North Korean authorities just released video of himapparently reading from a script, "confessing" to so-called war crimes. Kenneth Bae has been held in North Korea for more than a year and was sentenced to 15 years of hard labor. Steven Weber is a professor of International Relations at U.C. Berkeley.
