The North Korean regime lives on a different planet! This you know when you have something to compare them with: Malaysia vs the DPRK over the killing of Kim Jong Nam.
Kim Jong Un regime is clearly more unstable than his father's. One can expect and understand that during the change of regime but having being in power for several years this is how the North Koreans behave if really cause for worry. Meanwhile the Chinese have practically given up and telling mad Trump the DPRK is his problem.
If the North Korean government was unstable before, it is probably dangerously so now.
If the six powers especially America cannot resolve the debacle with the North Koreans then this will eventually be resolved tragically on terms worse than any we can imagine now even with a military solution.

Quoting from the end of the article:
Kim Jong Un is possibly more dangerous than his grandfather and father. I wonder if he understands what he is trying to do making other countries imagine that he would be easily provoked to launch a nuclear attack once he is capable of it. In this scenario, it would make sense to bumped him off or even attack and destroy the North Korean government. The question is whether China and the US would bit the bullet. The rest of us must understand that with Kim Jong Un in charge the peace we live under now would not last long, the longer we wait the higher the price we will pay to protect the peace. The path he is taking is utter foolishness. Of course as I write this on my mind is the recent simultaneous launch of four long range missiles suggesting that he would use a volley of projectiles to overwhelm any anti-missile defenses protecting American bases in South Korea and Japan.
