Yeah, how is it surprising that the country on the receiving end of the attack has a different viewpoint?
Given the lack of collective atonement for atrocities committed by the japanese, it feels like a form of whataboutism to me.
At the end of the day, both the allies and axis powers were constantly committing war crimes by targeting civilian pops. Hopefully this never happens again, but it’s not like it was unusual for any side at this time.
Definitely not in any of the countries occupied by Japan before and during the war.
