As we say, History is written by winners. Remembering the past is fine, but:
- Aren't you worried that the government omits some events in order to embellish its image? Typically Pennarossa2024 mention the rapes of the French army in Italy: this might be told to italians students, but except a line among a ton of chapters, it's not a thing in the French education because it doesn't serve the French narrative.
- Japan is nowhere close to what it used to be and could never reproduce the invasion of China even if it wanted too because the context is different. China isn't so late behind technologically speaking, like it was back then (and this can't be blamed on Japan; the Qing arrogance and Cixi's greed for power and boycott of the 100 days' reforms just led to the disaster). Japan nowadays is also traumatized by Hiroshima and Nagasaki, and the Japaneses certainly aren't bellicists people.
If Nanjing massacre and the war on the Asian side was certainly awful, it also feels like Chinese government is using it to keep alive some rancour and cultivate a strong nationalism in the younger generations. At least, that's my perception of the things because even if every Chineses will mention Japanese invasion as an horrible part of their history, it looks very much like Gen Z is much more nationalist and emotive than the Chineses of my generation I talked to.
I also agree with Chris when he says that this mindset led Europeans to fight each others quite a lot during the last 2 centuries and that French/Germans managed to go through that by letting past behind them, although nowadays, Germany gets back to its old habits...
JAP fascist are still alive
Maybe you focus too much on a minority. Everytime Japaneses or Japan government does a thing, it's instrumentalized, but you have fascists and nostalgic of some period of history in every countries. There are nostalgia for Mussolini in Italy, for Hitler in Germany et caetera. It doesn't mean that the majority of people are supporting it or that the idea is widespread.
If you go to Japan someday, you'd see that most of Japaneses absolutely don't care about China and Chineses and that many Chineses are either visiting or living in the country. Almost half of my lab was actually filled with Chineses students and a friend in another lab is simply married to a Chinese.
