You DO know the war never officially ended? There was a cease-fire agreement.

In the US, we have this thing called "trash talking" I don't know that N. Koreans understand what that is. If Kim Jong Un does, it's possibly because his buddy is Dennis Rodman, and there's a lot of trash talking in B-Ball.

Also, culturally, there's the whole "saving face" thing. Trump is all about bullying, including ridicule and threats. This pretty much guarantees verbal retaliation by Kim. I'm thinking the bullying is not going to have the desired effect, unless Trump wants Kim to knock that chip off his shoulder... with a nuke. Somebody needs to be the adult and shut up. We expect Trump to? And when we start pulling some people out of S. Korea, and sending others, we can all forget about diplomacy.
