Look back at the history of Democrat Administrations "dealing" with the North Koreans before you go off banging the Hate Trump drum.
He has made far more progress getting them to the negotiating table than every Administration/President before him.
Don't let your bias blind you to reality.
North Korea is bonafide threat to World Peace....without any doubt whatsoever.
Finding a way to get them into the mainstream of nation states and headed down the road to accepting they are secure from outside attack thus undermining their perceived need for Nuclear capability is paramount to achieving success in any negotiation with them.
Some food for thought......
