That's literally why my several members of my family voted for Trump. They really don't like Trump (they voted for Nikki Haley in the primaries), but they really like Vance and hope he'll take over at some point.
I was blown away, because I was under the impression that Vance was fairly universally disliked. I immediately responded with some equivalent of "clearly we watch very different news."
Here's a fact, there are an overwhelming number of north Koreans that support kim jong un despite it being insane. There is no saving these people. There is no walking them back. We either submit to their cause or they will drop the nukes themselves. The sooner we come to terms with it the sooner we know what must be done.
Asking north koreans rather or not they like their murderous dictator that will make their family disappear is not exactly a good indicator if average citizens likes him.
