Not sure I like the idea of the US president and the NK dictator being put on as equals symbolically. Hopefully something good can come of this but it may have been better through a lower ranking official meeting with UN.
But that's the entire idea - the "equalizer", Kim is no longer a "rocketman" — he is an equal, he stood up to big bully after making a "meaningful" offer of peace and disarmament... Not exactly USA - USSR / Reagan - Gorbachev.
