N.Korea's leader Kim Jong Un is smart as hell..
He saw how the US & Israel went about killing Iran's leaders, Ali Khamenei, in their illegal regime change madness, so he's taking no chances:

Well, on that score, Kim Jong Un learned a lesson that Maummar Gaddafi didn't. Gaffadi stopped his nuclear weapons project but the West still assassinated and toppled his regime.
😆🤣😂..so North Korea🇰🇷 says, if you kill our leader during any attempt at regime change, your ass is gonna get blown up!!

Sighhh..the whole world is going nuts!!!
