Thomas Lifson at American Thinker has an excellent essay on the current state of internal North Korean politics. Though he cautions us that, really, "no one knows anything," he produces this intriguing list of recent events inside that country, events which lend credence to Gordon C. Chang's claim that the bluster over the missile test may be due to internal pressure on Kim Jong-il's regime:
A year and a half ago, portraits of the Dear Leader started disappearing, but that crises passed, with no explanation ever reaching the public. There are recurring reports from defectors of anti-government movements being active. And there are the very curious reports of a train explosion in an area where the Dear Leader’s private train had passed only hours earlier. The regime subsequently claimed that the explosion was merely a planned excavation in a mountain, for a hydroelectric project.
