The International Crisis Group, an independent, non-profit, multinational organization, working through field-based analysis and high-level advocacy to prevent and resolve deadly conflict, writes, “While still preserving the Six-Party framework… the U.S. needs to talk to Pyongyang directly at the highest levels. At best this could result in a deal; at worst it might shed some light on North Korea’s motivations and aspirations. High-level engagement may seem to be rewarding bad behaviour, but it is also the only way any agreement is likely to be reached.”
ICG has also published supporting reports on North Koreans nuclear and missile program (available at: 09051BICG.pdf) and the DPRK’s chemical and biological weapons program (available at: 09051CICG.pdf).
