A very interesting article which sheds a light on how some higher ups in China (not all - there are many factions in the Party as we all know) view Diaoyu/Senkaku problem and how they chose 'symbolism' over peace and won't budge even if that means another great war to show the world who's the boss.
It is indeed very frightening, and portent ominous future for the region. For centuries China was a regional power and many "vassal states" at one time or another have "kow tow" or bend to the will of the middle kingdom. Therefore there are very strong believe in the country that territory that once "belong" (the rules of the strong) to China was taken away during when she was at her weakest and these propaganda if you will is willingly espouse by the ruling communist party either to build their credentials or grip of power playing nationalist sentiments.
China is a sleeping lion, Napoleon once warned. “Let her sleep, for when she wakes she will shake the world.” Then America probably still a "snotty little brat" where China was already the establish power of the old order before industrialised nation power their economic ahead and come knocking with gunboat diplomacy on her doors, what humiliation Japan and others inflicted on China, who can tell? There's a proverb saying for a gentleman to revenge, 10 years still not too late...but is a warning of revenge coming soon? Or will China follow Deng biding their time, hiding their capabilities, shelving this dispute to the next generation. Now Deng is no more, and we have a Xi (a next generation, in fact 2 generation after Deng)....who happen to love world war 2 movies, the opera and espousing a "new model" of great power relationship with Obama in a sunny Californian retreat. Xi is dreaming...the Chinese dream. PLA Navy is building up, the dragon is awakening and extending her grip, claws outreaching to the Indian Ocean and the Pacifics and lately Christmas island...and where is the dragon current gaze but on the pearls of islands she claim before and was "stolen"...while she sleeps. Very frightening.
