You are phrasing this as if it were possible to just magically make the Kim regime vanish, and the only reasons we aren't are self-serving and wrong. Your point #4 is far more important than any other: > "After deposing the Kim regime no one knows how to nation build while avoiding the usual quagmires." The fact is, if the west went in and blew up Pyongyang, do you really think there would be a peaceful transfer of power? I highly doubt it. Furthermore, Seoul is within easy artillery range of the North. No matter how quickly a hypothetical strike on the North was executed, Seoul will likely be at least partially obliterated.
