It is impossible to know exactly what is going on in North Korea, but something big has happened. The third generation Kim dynasty heir, Kim Jong-un, has been missing from public sight for a month, and may be ill, dead, or overthrown. There is much speculation, and contradictory reports are circulating, including the assertion that Pyongyang is sealed off, and no one is being permitted to enter or leave. But one fact is clear and it is dramatic. CNN reports: With Kim Jong Un out of sight for a month, a covey of North Korea's high officials popped down to South Korea for a last minute jaunt on Saturday, and delivered a diplomatic bonbon.
