Interesting that how many media outlets and government agencies arent taking these threats too seriously at this point*. I've got to admit Kim Jong Un's statements do have an element of 'No believe me I really am going to do it this time, and I'm running away from home too!' to them. This is possibly not unrelated to the fact that the DPRK gets more money every time it kicks up a fuss.
