In this Wednesday, July 25, 2012 photo released by the Korean Central News Agency (KCNA) and distributed in Tokyo by the Korea News Service Thursday, July 26, 2012, North Korean leader Kim Jong Un, center, accompanied by his wife Ri Sol Ju, right, waves to the crowd as they inspect the Rungna People's Pleasure Ground in Pyongyang. North Korea’s collapse has been predicted — wrongly — for decades. So it is no surprise that unconfirmed rumors that current leader Kim Jong Un is seriously ill have raised worries about what Washington and North Korea’s neighbors would do if things fall apart in any post-Kim North Korea.
