Victors get to write the history for their people I suppose.
I know the Germans are still ashamed of their history today, as they should be. And America is ashamed of some of our history concerning slavery (for example). So be it. I think Japan is pretty weird about their history.
I’m encouraged that teachers in Russia are allowed to even question this openly.
A nation that doesn’t revere their heroes, will eventually be ruled by a nation that does.
