Germany hasn’t come to terms with its past either. Look a little deeper.
The Germans talk about it, hold seminars, write about it and educate their people about it. All the Germans I have met are “aware”.
This is not to say they’re truly sorry for (as my late WWII vet father used to say), “...they’re sorry for one thing only, that they lost” their deeds.
The Japanese are in total denial because after Nagasaki, they’re all “Pacifists”.
