While that guy might give trump a little too much credit, there is definitely some truth in there. The part about western prosperity bringing down the berlin wall is 100% correct. It's not crazy to think that something similar could happen to on the Korean peninsula, if we could make sure Kim wasn't going to kill everyone out of spite.
Kim has an 80% approval rating now.. in South Korea?! Was 10% a month and a half ago!
I imagine the South is anxious to just be done with this whole thing. They get nothing from NK being a rogue state and general assholes, I am sure will jump feet first into any kind of peace. Hopefully it's not a trap.
Assuming he actually meets with Trump and progress is made.. I don't see Kim ever being put on trial or anything, which will outrage some people.
