I think if Kim Jong-un wanted to “end this” then there is a better way to do it.
He could be like Raul Castro (but more sincere) and say “Let’s normalize”.
He could say “Can we unify with South Korea?”
He could say “Come over to my house and build many factories!”
OR
He could invite us to nuke him.
The problem with North Korea is that even if Kim wanted to normalize relations, he’d be bumped off in a jiffy. And the people there are so brainwashed. It is going to take outside help to get rid of this regime.
Also, China and South Korea fear above all millions of Nork refugees pouring over their borders if the country plunges into chaos.
I certainly hope whatever the situation is, our intelligence community has a good handle on it.
