I have been following the saga of North Korea and nuclear weapons since 1990. It has been a roller coaster-like experience as the issue rises and falls, alternating between extreme concern and apparent relief that "finally" we have an agreement that will once and for all resolve the issue. First, North Korea agreed to join the Nuclear Non-proliferation Treaty (NPT). In early 1992 following U.S. withdrawal of tactical nuclear weapons from South Korea, it signed an agreement with the South to maintain a nonnuclear weapons peninsula. Finally, in 1994 there was the Agreed Framework. In each case, North Korea agreed to not develop nuclear weapons, and in each instance, another agreement was necessary because Pyongyang was not willing to abide by the previous agreement.
