The Korean Peninsula was once divided into the three kingdoms: Silla, Baekje, and Gogureyo (or Goryeo anglicized as Korea). It was the Goguryeo kingdom which was the largest kingdom in the history of Korea, stretching from the northern part of the peninsula into Manchuria, Northeast China, and Eastern Mongolia. Lifestyle in Goguryeo was both nomadic and agricultural, as they had a patch of Eurasian Steppe to support nomadic life, but not enough to be fully nomadic. Because Goguryeo was largely where modern North Korea is it's been hard to ascertain the genetic makeup of this kingdom, though thanks to a study of DNA from southwest Koreans, who descend from the North Koreans that migrated from Goguryeo to Baekje, it has been found that the genetics of these Koreans is distinct from the modern Korean population. While most modern Koreans are a member of Haplogroup O, there was a higher prevalence of Haplogroup C and possibly even Haplogroup R1a (prevalent in Eastern Mongolia) found amongst this population. This means that this population is more related to Mongolians than the typical Korean, who, although being a descendent of Mongols, is distinct. North Korea's seclusion makes it the most noble modern state. The nation's refusal to participate in globalist politics and banking while amassing a nuclear arsenal makes it subject to more propaganda than it subject its citizens to. Kim Jong-Un and the rest of the Kim family are high caste Mongolian Khagan descendants, phenotypically nearly identical to Mongke Khan, at least as depicted in the Yuan Dynasty portraits. The Kim bloodline in North Korea is called the Paektu bloodline, Paektu is a massive anomalous volcano on the border of China and North Korea, which represents the greatness of the Korean people, a volcano so far north it's partly in China. The North Koreans are a genetically distinct and higher caste Korean stock, implied by reference to this great bloodline from the North of Korea at Paektu.
While Mongols have spread their genetics across the world, North Korea has remained fervently isolated, and likely has one of the purest genetic makeups in the world. One of the most troubling things about a great race is what comes after the conquering, that is, genetic admixture, multiculturalism, and empire. The Mongols were invaders, but not colonizers, there was no perceived virtue to their action, no idea of 'civilizing' or amassing an empire, at least not in the Anglic sense, but more so in the Aryan sense. They raised their flag on conquered land and moved on, impositions of their culture was not their primary intention. Greatness spreads like water, it just wants to travel as wide as possible. But since industrialization there is hardly a translation of greatness into power. Where Nazi Germany's greatness and spirit is defeated to the USSR's and USA's raw production power, and Mongols live simple, traditional lifestyles. At this pressing time, there is nothing for the North Koreans to do but isolate and remain whole, while their ancestors conquered the world, they create for themselves an isolated Hermit Kingdom, so they may feel greatness while the rest of the world it subject to evil.
