Furthermore, I'd question the value of finding out for yourself what life is like under a famine-stricken, xenophobic, totalitarian, hereditary absolute monarchy. What is it you're hoping to get out of an experience like that?
In the case of North Korea: It's difficult to explain unless you're in a listening mode, but I'll try:
First: I would never go under the current government. Full stop. I won't go somewhere where I don't feel safe.
Second: I don't endorse their government in any way.
For me, the best analogy would be traveling to East Germany in the early 1990s after the fall of communism. IE, visit the Berlin Wall, and maybe listen to some locals tell their story.
So, assuming North Korea's government changes in my lifetime, I'd love to visit and "see it" before it gets torn down.
One of the things I like hearing is how people work around constraints and obstacles. These are the kinds of stories I'm interested in.
(BTW, a good friend of mine told me he's been skiing in view of the DMZ, and they just laugh at the NK guards watching them ski with binoculars.)
