This case study examines the negotiations between the United States and the Democratic People's Republic of Korea that resolved the September 1996 incursion of a North Korean submarine into South Korean waters, leaving more than a dozen South Korean civilians and soldiers dead, along with the sub's crew. The case demonstrates the unique nature of three-party talks where only two parties sit at the table, and offers important insights into the interagency process of U.S. diplomacy. Written by a member of the U.S. negotiating team, the study looks at how far a negotiator can push the interagency process.
