The handshake (at about 13 minutes in the video above) between North Korean Supreme Leader Kim Jong Un and U. S. President Donald Trump pretty much says it all. It is just a little too long to be comfortable; both parties are clearly vying for dominance. The symbolism of the event is important. The meeting itself didn’t accomplish a great deal other than that. It isn’t even the beginning of the process. That began some time ago with meetings, not nearly so highly publicized, between CIA Director Mike Pompeo, Kim Yong Chol, and, I presume, others.
The North Koreans mean something different by “denuclearization” than we do. For them it’s the U. S. vacating the Korean peninsula. For us it’s complete North Korean nuclear disarmament. What will come of this meeting? Who knows? It’s something.
