Aidan Foster-Carter, honorary senior research fellow in sociology and modern Korea at Leeds University, writes: “the Dear Leader has trouble at home too. Six-party fixations have also distracted us from internal North Korean politics: a murky area, but one where hidden eruptions begin to ruffle the bland theatrical veneer. Last year Kim purged his brother-in-law and ex-right-hand man Chang Song-taek. Three sons vie to be dauphin, with rumors of murder plots (in Vienna, even). This struggle may be over policy – hawks versus doves – or simply power. Either way, stability can no longer be taken for granted.”

John Feffer, author of “North Korea, South Korea: U.S. Policy at a Time of Crisis“, writes: “The new team at the State Department should consider how a more flexible U.S. negotiating position which would deal with the plutonium program first and provide incentives throughout the dismantlement process rather than just at the end could solve one of the world’s most pressing problems and, improbable as it might seem at the moment, provide George W. Bush with a positive legacy when he retires.”

Leon V. Sigal, director of the Northeast Cooperative Security Project at the Social Science Research Council in New York and author of “Disarming Strangers: Nuclear Diplomacy with North Korea“, writes: “North Korea is the embodiment of evil to some Americans, who object to making a pact with the devil. Why they prefer to bluff and bluster while watching North Korea adds to its nuclear might instead of disarming it through give-and-take is a mystery of their faith.”
