Kim Jong un has been noticed!?

Kim Jong un

At the end of a week in which North Korean leader Kim Jong Un shattered the illusion that his rule would mark a departure from bellicosity, signs are emerging that there may be method in his apparent madness.

His motivation is not war, but simple regime survival, top-level defectors in the South have said.

The 20,000 North Koreans who have made new lives in the South since the end of the Korean war in 1953 are among the few people placed to give reliable insights into a country that often generates more speculative heat thananalytical light.

While they are divided on how far Kim will to go in his campaign to pressure the US and South Korea into offering talks on aid and a peace treaty, they say he is as aware as officials in Washington and Seoul that all-out war and the continuation of his dynasty are mutually exclusive.

"Kim Jong-un's aim is to unite the North Korean military and people around his regime and win their trust," said Jang Se-yul, a former mathematics professor who spent 10 years in the cyberwarfare unit of the North Korean army in Pyongyang. "They don't trust Kim yet, and they're looking for strong signals from him."

All for trust? This young ruler is truly mad.
