At least in the case of North Korea, I very much fear that in a decade or two the place will go dark and the rest of of the world (ourselves included) will find a mausoleum of a country.

We'll all kinda go, "Well, we couldn't just invade them, could we?", and just silently acknowledge that everyone in the world sat there while millions of people were starved, butchered, or tortured.

And then we'll probably have a fight over what's left.
