you really think that NK is serious? It desperately needs to have the tough sanctions reduced or removed, so they are playing games. NK, like Iran, cannot be trusted. Trump is playing to his supporters. The fact that he, like here in the UK, has been too quick to judge Russia on the poisoning of the spies in the UK, without any hard evidence; and again in his blaming Russia for the chemical attack in Syria, with no evidence to support. Trump will be the looser on China, Russia, NK and even Iran and the nukes.
