A change of power, it seems, maybe. Kim-Jong-un is being lined up to take over with Kim Jong-Il supposedly less mobile now after a couple of strokes.
The son wasn't officially known about until a few years ago. He may have been born in 1982, 1983 or 1984. Some think he's had an education in Switzerland and is fluent in English. It really is amazing just how little we've managed to permeate into North Korea.
But I suppose the main issue is will the change of power do anything for North Korea? If he's had a western education, will there be any changes in policy, and an improvement in things in North Korea? Or will the son be more in the Uday/Qusay Hussain mould?
