Here is a guess about the Korean peninsula

The present leader of North Korea will die from getting old. Now by nepotism, he inherited his position from his father, and he was savvy enough to survive. Now will his chosen son inherit it in the same way; most doubt it. I agree.

What happens when the people who live in North Korea evolve in this case. Mostly most think they just want to live (like eat and have families), but other factors come into play, too.

Many will move to a better place, like South Korea, and some will move to China by the border area. All this emigration will cause much friction. In the meantime, normal Korean practices from the South will also begin to assert themselves. But in the same time, there will be a Korean uniting that will take decades to enhance. In all this there is hope.

The future debate to this westerner is how will it all sort out. My guess is just fine. There may be surprises along the way.

The idea is that Koreans are different than, say, Japanese, or any kind of Chinese.

Now there are wild cards. For example, will the humans who rule the present government in North Korea go nuclear in some way? Or will the USA government choose some military option response. Or will we just let it go?
