The founder of North Korea's ruling dynasty, an isolationist totalitarian leader named Kim Il Sung, was still building some of the country's first nuclear facilities when Syd Seiler arrived on the Korean Peninsula as a young U.S. military intelligence officer.
Over the four decades since, Seiler has watched closely as Kim, his son and now his grandson have clung to their nuclear program and developed the potential to lob nuclear warheads at the U.S. and its allies if they choose.
