I honestly can't blame the Chinese for getting upset over the Japanese history textbook thing. Although it might have been more appropriate to throw things at the Japanese embassy rather through the windows of Japanese businesses who, after all, probably weren't around at the time of the brutal Nanking massacre.
As they say, history is written by the victors, and in this particular war the Japs won. On the other hand, if one wants to apologise for torturing, raping and murdering citizens of one's neighbour and trading partner then actually owning up to it is a damn good start (and paying compensation would also go a helluva long way too). I don't have anything against Japanese as individuals, but what they did as a country all those years ago affects me more than what I know of the Holocaust - because the victims were my parent's countrymen.
