The North Koreans have pretty much laid down the whole sequence of the events that they plan in order to bring about their goal [of taking over South Korea]. First, a nuclear threat to U.S. territory, then an American failure of nerve, then a peace treaty, then withdrawal of U.S. troops, then confederation, then unification [under the North Korean regime]. This can be pieced together and inferred from the leaders' own speeches, from North Koreans' inner-track propaganda, in other words everything from wall posters to political novels. We've heard this from captured North Korean operatives who've divulged their ideological training to South Korean intelligence. So, we do need to take it very seriously and we do need to understand this is a long game that the North Koreans have been playing since the 1980s.
