Hey--get out and dont make this situation complicated. If any US citizen stays --count them as lost and a casualty.  Abandon NKo and let them rot--hopefully the people will rise up and off the terrible people and regime--get rid of the threat.  Maybe NKo will turn to China and them have a falling out--and both China and NKo can be at odds and off each other.  USA can pick up the pieces later.  If not -- Next missile that goes up--blast it out of the air over NKo.
