Reminder & Predicion:
The Ancestors of the Koreans killed the King of Earth aeons ago. The King of Earth didn't resent them for doing so, of course he wasn't happy about beeing killed either. They've been of his spirit and he loved them thus he forgave them.
Since then the Koreans followed "the law". They didn't replace the King of Earth and guarded his throne so noone will sit on it ever again. Today only pepples of the Throne remains, nothing of use to anyone. However to this days the Koreans retained the power their Ancestors used. No matter what, no power on earth could defeat them. It's not about Nukes, it a spiritual kind of power.
If anything, there wont be a War between North Korea and the USA. When pushed to hard, they'll go straight to fight the real source of conflict, the jews.
