I think a reunified Korea would ultimately rival China as the dominant power in the region. It happened in Germany, it can happen in Korea. Germany is far better off now btw.
I don’t see a comparison of the two peoples. IMO N.Korea’s people have had 50 yrs. of brutality and brainwashing. Their entire infastructure is gone as well. How do you catch a people up living in an era 50 yrs. ago? Not to mention rewire their thinking about the rest of the world?
A mindboggling task. But I am hopeful something can be done just the same. Horrible state of affairs there.
