What about North Korea? The worst communist regime on the planet.
IMHO, President Trump has encouraged Kim to engage in commerce/business in order to bolster NK’s people, as opposed to expanding their military stance. I think the mentions of Kim without rancor feed Kim’s ego and catch him off guard, so he hesitates or turns away. For a while anyway.
Maybe Kim likes PTrump. Actually going to NK as POTUS does have an impact.
Long term is a we’ll see what sticks kind of thing. Antipathy is cultural.
NK has not known liberty for how many generations?
