Wrong, their feudal society literally thrived on unquestionable obedience and the full knowledge of brutal cruelty to those who lose or fail to fight until they die.
Culturally they were bankrupt as a nation which led to millions of massacred Chinese, massive rapes and enslaved Koreans, much in the full knowledge of the average Japanese citizen as war spoil.
You arguing they were unaware of specific war crimes means nothing because in the larger context the Japanese Citizen understood this was the way of how they waged war and treated those not of their own lineage.
Your sophist assertions and obfuscations will not fly here unchallenged.
Claim what you want. Yet you provide no citations, primary references, etc that the average Japanese citizen was aware of this information.
It certainly did not come from Japanese media during WW2, as the military, went to great pains to hide their torture of Allied forces and subjugated peoples, as research of the Rape of Nanking and other war crimes became known.
The Japanese people were told and believed they were a superior people to other Asians and that Westerners had abused and tortured Japanese in years prior. It’s a stretch to claim that this was tacit endorsement of torture.
Please provide a book or reference that buttresses your claim even in the broader sense.
