dynamic the other way imo, in treating Japan softer than we would “one of us.” I think part of the treatment also is we were (the US government) just eager to help Japan rebuild and become an ally — heavily recriminating the past of a very proud people doesn’t help in that. Sure there were war crimes trials but we let them move on and to this day Japan is in denial of what they did.
Also, Jewish influences have made sure that we “never forget” and have kept the Jewish Holocaust firmly present in Western consciousness. That might be the biggest difference of all. It happened in the West, to people with large cultural influence in the West. Of course it’s going to loom magnitudes larger than things that happen elsewhere. How many shed a tear for tragedies that routinely happen in Africa and Middle East for decades. Yet everyone had a France flag up on their social media after the 2015 terrorist attack in Paris.
