N. Korea is S. Korea’s problem. S. Korea is rich and can defend itself. They have bitched forever about our presence and believe in feeding the monster. They only wasy to solve N Koreas is to cut off its head and the support structure. But no western country has the will or desire to do so.

It is a shame we do not have for real a 007 that goes in and kill the head. But we eschewed assasination as a tool.

Otherwise I would leave N Korea to stew and starve. Keep ABM nearby for possible launches and interdict any shipments that spread N Korea arms and nukes to others. Cheaper and less hassle. Probably what we are already doing.
