Within hours of the news of North Korea's nuclear test breaking yesterday, the following video was published on Tudou, which is the most prominent of China's Youtube clones. It is a clip from Phoenix TV in Hong Kong about the North Korean's nukes.

Also relevant, this clip from the film Team America, hosted on Youtube:

Finally, it is worth considering this comment from an opinion piece in the Financial Times by Gideon Rachman:

Ronald Reagan, former US president, is said to have told Mikhail Gorbachev, former Soviet leader, that the differences between the US and the Soviet Union would pale into insignificance if the two countries were jointly faced with a threat from Mars. Mr Kim is as close to a Martian as anyone in world politics. If his nuclear posturing provokes the big powers in east Asia to bury some of their differences and work together on making the region more secure, the North Korean dictator may ultimately have done the world a favour.

The weekend's state visit to China by Japan's new prime mininster Shinzo Abe seems to be proof of that theory.
