Re USA/NK Presidents...both Kim Jung Un, at 27, and Donald Trump, at 71, are well known to be equally very thin skinned and to take personal insults very seriously. Trump attacks his enemies in the media, whereas Kim Jung UN puts them 10 metres in front of an anti-aircraft missile, and fires it through them. Neither is afraid to risk everything, yet both are quite and equally bright and most interested in their own survival. We will see who is the first to seek dialogue. I expect Kim Jung Un will outlive many US Presidents.
