Do you really think that this is so? Almost to much to comprehend
Certainly unexpected, but it's rational as all getout. East Germany fared very well when it reunified with the west. South Korea has much to offer. And if NK is a shadow state, really run by rogue elements of CIA and similar actors from other countries, all the government would have an interest in changing that dynamic.
Is it so today? I don't know. Is it inevitable? No. But it sure makes sense. Nutcase Kim could become as a God in history, to his people, considering the change in standard of living they would enjoy.
