Before and during WWII the Japanese emporer was believed to be a god by the populace. None but the highest military and civilians ever entered his presence.
No commoner had ever seen their emperor or even heard his voice on the radio.
Even though the Kim family of dictators have made speeches and are seen on television and at functions they have taken on the god cloak.
A god figure can not negotiate.
They can only be destroyed.
When China chokes off their supplies and markets, and Donald starts making clear to him what the US can do, he’ll start backing off slowly to save face. He’s started that already, in fact, saying that now North Korea’s nuclear arsenal is complete; in other words, no more tests. He’ll keep the god thing going, but North Korea doesn’t have a long tradition of godhood myths for their leader, as Japan did, nor any empire worth speaking of. So what’s he going to do with it?
