I had a conversation with my mom about the anniversary of Hiroshima and Nagasaki. She insisted that the Japanese must never forget the atrocities they visited upon the Chinese. I agreed, but said that it was also dangerous to generalize.
The Holocaust was performed by the Nazis, as differentiated from the Germans, but the Japanese are just the Japanese. I don't believe the Japanese of today are the Japanese of yesteryear, but then again, I'm no historian. I'm told they have done this kind of stuff time and again.
On the other hand... It seems like the Germans have a pretty hard line against all things Nazi. A friend of mine went to Germany and found it a very nice place. So nice, in fact, that he asked a passing German where all the ghettoes were. In Germany, this means something completely different. The German in question looked flustered and said, "We don't have that kind of thing anymore!" So the question, then, is "Are the Japanese embarassed by their transgressions?" Are they contrite?
It seems like every year I hear about the Chinese demanding an apology from the Japanese, and I seem to recall that they do. Like, the Americans with Pearl Harbor.
Of course they lost the war, but they moved on and created one of the world's major economies. Japan's a large source of artistic creativity. They're emulated just as often as they're mocked, if not more so. Everyone knows and admires their technology. Japan as a nation moved on, which is why the Japanese of today aren't the Japanese of yesteryear.
I have a feeling that a lot of Chinese people look to the past and remember their country's former glory as well as its injuries. Not just those directly touched by the war, but current generations.
