In fact, modern North Korea is a 21-st century Asian monarchy based on the template of the 500-year-long reign of the Choson Dynasty and ancient Neo-Confucianism: emphasizing clearly defined hierarchies, centralized bureaucracy, obedience to the state, and social stability—elements of great use to modern despots.
