The Japanese still hold their Emperor in great esteem. Much more so than the British cherishing their royal family or any other nation who has a monarchy. The 14 or so war criminals at the Yasakuni Shrine were criminals. There is no doubt about it. But the Japanese still wish to honor them and not move them to another burial location because they are grateful for their sacrifice. What sacrifice? MacArthur had told the Imperial Japanese government that in order to save face for the Emperor, they must take the blame for their actions so that the blame for Japan's war of aggression does not fall onto the Emperor. In other words, in order for the Emperor to remain status quo, he had to be spared from the blame. The war criminals killed themselves or they admitted to their war crimes and were executed. You can call them human scum or whatever and certainly they were racists and bastards but they were all loyal to their Emperor, as most Japanese are. And their sacrifice preserved the legitimacy of their Emperor.
And so that is why the Japanese people are "grateful" for these war criminals and continue to do them honor at the Yasakuni shrine. I personally do not agree or disagree with their worship but I think China needs to re-evaluate Japan's point of view. China seems to think that just because Korea and Vietnam were also attacked by the Japanese, somehow there is a bond between the 3 of us and that Japan is a common enemy. You can throw that out the window. There is no doubt that Japan DOES whitewash its textbooks but are the koreans and vietnamese innocent? If China wishes to truly look into it, they will find that both Koreas and Vietnam have plenty of anti-Chinese content in their education. Of course, the indications are subtle but the implications are there.
Why is China holding a double standard? Why use Japan as a scapegoat? Trade has suffered greatly because of this issue. The Koreans are benefitting greatly from China-Japan dispute economically. Why is China giving the Koreans such favoritism when Korea teaches its own people anti-Chinese content as well, possibly even more so than Japan? Chinese certainly need to re-evaluate who their friends are. Korea is no friend. And Japan is not an enemy.
