Almost certain aftermath photos are included in textbooks when I was in school. As well these images are found on the internet.
I know these things aren’t mutually exclusive but Japan should focus more on apologizing for its own atrocities in WWII that led to the necessity of the bombs. The Rape of Nanjing had as many innocent deaths as the 2 nuclear bombs combined.
(Also also it seems to get overlooked frequently, but the Allies could have kept fire bombing cities and it would’ve caused far more deaths then the atomic bombs caused.)
