Your North Korean succession story explained:
The current leader, Kim Jong-il, has three known sons. The eldest, Kim Jong-nam, was once considered the leading candidate to succeed his father, until the Disneyland episode added to rumors that his judgment was less than reliable. Kim Jong-nam is widely reported to have voracious appetites for alcohol and women, and his father apparently grew concerned that North Korea's generals would never accept him, according to a former American intelligence official.
The North Korean leader's middle son, Kim Jong-chol, 28, was another possibility, but Kenji Fujimoto, who once served as Kim Jong-il's sushi chef, wrote in a memoir that Kim Jong-il dismissed that son as "girlish," suggesting that he would not stand up to the West.By default, that left Kim Jong-un.

"Disneyland episode"?
how'd the sushi chef escape to write a book?
It'd be cooler if he picked Erica Jong.
There will be a nuclear accident involving the launch of a short-range missile mistaken for a long-range missile, and the three sons will merge into a highly radioactive monster named Namcholun, which will immediately begin producing spice melange and embark on a thousand-year Reich.
A long time ago, in another life, I served in the intelligence community, specializing in our friends in the DPRK. The reality is that they are a bad joke. Millions of starving people trapped in a dictatorship. No real economy to speak of except for some natural resources that the Chinese plunder in exchange for propping up this ridiculous government. They are a buffer state created and sustained by the PRC. Nothing that they do is not sanctioned by the highest levels of the PRC. Think about it in that way and you'll begin to see that there is no danger of nuclear proliferation from the North Koreans (given that the Chinese haven't done it for the last few decades since they became a nuclear power). North Korea is a puppet of the Chinese and enables them to destabilize the region and maintain a confrontational relationship with Japan and South Korea, their two main economic rivals...
