The Juche leadership is terrible, but neither it nor the Kim family are actively insane. Behind almost every posture and threat of theirs is a message.
Kim Jong-un is a new leader, and not as secure in his position as Il-sung or Jong-il. He must first prove to the DPRK military that he's going to give them the same preferences Jong-il initiated and to the Juche ruling class that he's pliant. And the latter and the former might sometimes be at loggerheads.
I dip my forefinger in the watery blood of your impotent mad-redeemer (your Divine Democrat — your Hebrew Madman) and write over his thorn-torn brow, “The true prince of Evil — the king of the Slaves!”
- Ragnar Redbeard, Might Is Right, 1890
