It's pretty clear to me that this biased article was written by the Chinese press because they call "the Senkaku islands" "the Diaoyu islands".
Miyazaki may be a great anime creator, but he is NOT an expert on historical and political issues. Some Japanese people criticize Miyazaki's comments because Japan have already apologized over 20 times about its imperial and wartime aggression and those past apologies and the compensation paid to other countries have been ignored. In general, Japanese people think that Japanese invasions to Asian countries were wrong, Perl Harbor attack was wrong. Some Japanese right wingers think Japanese invasions were no different from Western Imperialists invasion over Asian and African countries. They are annoyed by the blatant double standards. Western countries like Britain and France never said "sorry" about their wartime past, and China never demand an apology and the compensation from Britain for the Opium Wars. It's amazing and ironic that the Japan haters themselves are engaging in the very behavior that they accuse Japan of doing, which is ignoring the past. If you think that sorry state of historical reflection is bad, you need to see how the other countries have reflected on their past.
As for the territorial dispute, the US should stick up for Japan because of the fact that it was the US that returned the Senkaku islands to Japan in 1972 along with Okinawa. In 1971, the US President Richard Nixon confirmed Japan's "residual sovereignty" over the Senkaku Islands just before a deal to return Okinawa Prefecture to Japan, according to recordings and other materials kept at the Nixon Library in California. Nixon made the confirmation in a conversation with his national security adviser Henry Kissinger. The CIA also stated in related documents that the Japanese claim to sovereignty over the Senkakus is strong and that any dispute over the islands would not have arisen had it not been for the discovery of potential oil reserves on the nearby continental shelf in the late 1960s.
At the end of the day, Japanese people are fortunate to have freedom of speech and freedom of choice. You can't expect any famous person in China to officially make comments like ""Chinese government should apologize to Tibetan people" . It's silly to me that a country like China that is a dictatorship with a history of brutal repression and human-rights abuse taking place NOW, have the hypocrisy to criticize the actions of a present-day democracy. In truly civilized countries, media is free and protected under the constitution, and people can express their own views. Under the CCP, it is controlled and used only to promote propaganda.
