North Korea is no longer a Communist state. Nor is it a military state. It's a monarchy.
Kim's successor has been identified, and it's his youngest son, Kim Jong-un. A recent general, moreover, has stated that the military will always support and defend Kim's "bloodline". Jong-un was described by his former sushi chef of being just like his father: “He has superb physical gifts, is a big drinker and never admits defeat.”
No word on whether he's crazier or not.
