The Soviets tried to. A lot of German families did not survive the Soviet occupation. Americans fought hard in Europe because the saw the global threat posed by Hitler and the Nazis. But as many said already on this post. Germany did not attack the US on US soil. There was a good bit of U-boat attacks on American shipping. Even right off our Atlantic coast and we really let that go on for too long trying to stay out of the fray. But most Americans did not feel the way about Germans turned Americans as they did Japanese Americans with close ties to their homeland after Pearl Harbor. As for the A-Bombs, I would have preferred instant death to torture and slow starvation on the Bataan Death march or Japanese POW camps. War is not civilized but we fought with honor against the Japanese who had no honor in this War. Then we helped rebuild Japan and the non Soviet held parts of Germany. I feel that if the treaty following WWI had not been so oppressive, Hitler would have never rose to power.
The “America was wrong to nuke Japan” crowd doesn’t seem to get it.
It took 2 nukes to get the Japanese attention, one wasn’t enough.
Even then when the emperor announced surrender, the Japanese military had to fight against other Japanese military because they had no intention of quitting.
I’ve read where they were expecting 1 million allied casualties with an invasion and possibly up to half of the Japanese population.
