this isn’t specifically a Japanese thing though, most American kids are taught that dropping both bombs was the only way to win the war, when this is still the subject of a lot of debate. for that matter, they probably aren’t taught about how eugenics were effectively exported from America to Germany. I’m from the UK and I had to wait until I was reading history for fun to learn about most of the UK’s colonial crimes. the way history is taught in schools is just a bit shit
