"North Korea set on third nuclear test"

It might be related, but on the other hand I concur with the authors in terms of this being a `when not if' situation. I also expect them to do some things to try to look strong at China's expense. It's very hard to predict what they'll do however because their government is pathologically irrational, and it's not restricted to one area of government, or only a few of their leaders. The crazy runs deep in that country.

To give one example (of which perhaps there are no end...), my first thought was that they might wait some period of time until after Hu's visit to the US had concluded and settled down some before they lit new fires. Then I remembered that they most recently broke the armistice in the middle of China's hosting of the Asian Games. When that happened I was pretty surprised at the level of disdain for China's interests that they demonstrated with that aggression.
