Korea is fascinating and unique. A country that was once part of the Chinese Han Manchurian Empire, and was granted total Independence as a Nation by China a long long time ago, and then basically obliterated by, firstly Japan, then US and USSR, so obliterated that the country was split among warring brothers into North (supported by USSR) & South (supported by Western Forces)...a country that has remained 'at war' with itself for over 60 years. There is only one Korea. These two warring brothers should be left to work out their differences. It wouldn't take long. If every other nation just kept within its own borders, then Korea would be unified pretty quickly. It wouldn't be pleasant, but it would resolve itself; the Korean Family would be as one and work out all their differences. When you look into the culture of Korea, the missionaries bringing Christian zeal, the shamanistic indigenous notions, the reign of confucianism, then Japanese Shintoism, invasion etc, and in the North, the Rise of Juche etc, you can understand both the rise and continuance of someone like Kim Jong Un and also the bizarre religious leader Church of Unification in the South Sun Kyun Moon...and it will have to come down to the Korean Brothers in some kind of slugging match. No real need for anyone else to be involved.
