Yesterday North Korea tested a nuclear weapon under ground to the out cry of many countries around the world. Many people are contrasting Iraq's lack of WMDs with North Koreas apparent nuclear test. However the big difference is korea's next door neighbour China. North Korea is pretty much under the Chinese thumb with China providing a life line to the country. And in return China uses North Korea as a lighting rod to defect attention from it's own problems. But the erratic Kim Jong-il must be worrying for even China.
