It would have saved a hundred million lives and hundreds of billions if we nuked Moscow after Hiroshima and Nagasaki.
True, but you gotta remember that we went to war and made Germany the #1 priority
to save the USSR, in the minds of many in the Federal Gov't. Despite being attacked first by the Japanese. These were the same folks who said it was none of our business right up until the start of Operation Barbarossa.
In many ways, WWII was the war to save totalitarian socialism from the wrong brand of totalitarian socialism. We "won" and got 45 more years of socialist totalitarianism in Europe. If that was the war aim, we performed
brilliantly. If not, I think I can find some flaws in execution.
