Will nukes creep into Bill Clinton's North Korean agenda?

A door could open to progress on issues including North Korea's nuclear program if both the U.S. and Pyongyang gain something from former President Clinton's surprise visit Tuesday, some longtime analysts of diplomacy with Pyongyang say. "This is not a zero-sum game, and if both sides get what they want, then it's a win-win that everyone should be able to live with," says Jim Walsh of the Ploughshares-funded Massachusetts Institute of Technology's security studies program. "Beyond that, the possibility is always there that a satisfied Kim Jong-il could change with the wave of a hand the trajectory of U.S.-North Korea relations."
