To North Korea, diplomacy is another form of war. - Brian Reynolds Myers

Korea's northern border remains easy to cross, and North Koreans are now well aware of the prosperity enjoyed south of the demilitarized zone, Kim Jong-il continues to rule over a stable and supportive population. Kim enjoys mass support due to his perceived success in strengthening the race and humiliating its enemies. Thanks in part to decades of skillful propaganda, North Koreans generally equate the race with their state, so that ethno-nationalism and state-loyalty are mutually enforcing. In this respect North Korea enjoys an important advantage over its rival, for in the Republic of Korea ethno-nationalism militates against support for a state that is perceived as having betrayed the race. South Koreans' "good race, bad state" attitude is reflected in widespread sympathy for the people of the north and in ambivalent feelings toward the United States and Japan, which are regarded as friends of the republic but enemies of the race.

To assume that the two Korean administrations do not already see each other as confederates, and behave accordingly, albeit discreetly, is like assuming that a man and woman planning a marriage are not yet having sex. When we ask for Moon’s help in getting the other half of the peninsula to denuclearize, we are in effect asking this fervent nationalist to help remove the future guarantor of a unified Korea’s security and autonomy. Why should he comply? The only remaining point of the US-ROK alliance is to ease the transition to a confederation — which would obviate that alliance altogether. The recent news of South Korean violations of sanctions (and of a presidential award just given to the main importer of North Korean coal) is merely illustrative. It’s trivial in comparison to the basic truth staring us in the face: No true liberal-democratic ally of the United States would think of leaguing up with an anti-American dictatorship, let alone one still in the thrall of a personality cult.

[O]ne's political ideology is inextricable from one's view of history.
