Kim Jong Un
There is a famous story about the late Frank Sinatra and the late comedian Don Rickles which seems apropos for the recent dealings between Trump and Kim.
Frank Sinatra was in a restaurant in LA when he was approached by his good friend comedian Don Rickles. Rickles told him that he was having dinner with some very important people and could Frank possibly drop by the table and say hello. Sinatra said he’d be happy to. Part way through the dinner Frank Sinatra gets up and approaches Don Rickles table. He stops and taps Don Rickles on the shoulder. He says “hi Don. It’s great to see you, thought I’d just come over and say hello”.
Rickles looked up at Sinatra and in a loud irritated voice said “Frank, can’t you see I’m busy here.”.
Kim’s suggestion of a meeting followed by negative rhetoric is a page right out of Don Rickles book.
That being said, I would prefer the late Don Rickles as a leader over Trump or Kim.
