The combined casualty count from the 2 bombs ( about 225,000 people mol) was NOT the greatest “atrocity” in WW2.
It gets more attention because it was the first use of a new technology to kill a large number of people all at once in seconds, instead of the slower process of firebombing them,mass gravity bombing them, blowing dikes and flooding flooding them, lining them up beside pits and running marathon executions, gassing them in chambers, raping torturing and bayonetting them ( a Japanese specialty), slow death by exposure and starvation in prison camps and forced labor camps ( 70,000 died fast at Nagasaki, 30,000 european civilians died slowly in Dutch East Indies prison camps and up to 800,000 Koreans forcibly sent to labor in Japanese mines and factories also died slowly)
I didn’t see China today, which had 20-35 million people killed by Japan, choosing 6 August to bring up accusations on Russia ….
Btw, the Japanese military council did NOT surrender after Hiroshima.
Only after Nagasaki.
