A major and often overlooked reason to force an end to the war. That and the fact that the Japs were willing to all die and take us with them sealed the deal.
I have read extensively about WWII all my life. The enemies in Europe were seen and (generally) treated as reasonable combatants.
In the Pacific the Japs were viewed like cockroaches who could only be subdued by killing the lot. There was no reasoning with them and the mentality that they would die to serve their emperor was totally alien. Starting Leyte Gulf and suicide fliers which terrified our Navy I think the die was cast to end the war no matter how. Just my 2¢
I have a distant union member and communist uncle in Europe, and when I came to visit he kept ranting against America, but one day he pulled me aside and said: “why did the US drop 2 nukes on Japan? They should have dropped a DOZEN! These people are crazy slave work and war maniacs! “
