I have always said, and maintain it is still the case, that North Korea does nothing it does without the full blessing of China. PDRK 's supposed insanity and threats helps China retain it's stronger position in Asia-Pacific by being the "good guy" and builds the image of the country that keeps PDRK in check, while it is actually the main catalyst for the instability it purports to reject. In other words, PDRK only acts on Beijing's orders. China will thwart any and all attempts to reign in PDRK because they are able to influence global policy using triangulation. But it is all smoke and mirrors. China wants instability and a "crazy cousin". It takes the negative spotlight off of their militant ambitions-just read every single 5 and ten year plan their communist party has prepared for over 30 years. They are communists and no matter how much lipstick they put on it, a pig is a pig.
