done4good - Interesting info thanks.
revip - NK do not yet have the capability to launch a nuclear missile at anybody. Reducing the size their bombs to make it possible to put on a rocket is a challenge they have yet to conquer.
NK is an irrational cult. Hatred for the US is its central tenet of faith. Movies of the USA burning up in a nuclear conflagration are normal on state TV. It is a national mental illness. Imagine having a psychopath living next door to you who screams constantly about how much he wants to murder you and your family. ONce NK has a viable weapon it will effectively be living next door.
I do think it will attack America if it can't be persuaded otherwise. NK is not Iran. Not even similar.
