The bombings of Hiroshima and Nagasaki saved American lives and saved Japanese lives. The lesson is ‘don’t make war.’ I think the Japanese learned it.
In fact, you'd think the whole world would've learned a lesson about attacking America, but many in this world are itchin' to take us on. The only lesson I can draw from this is we were not harsh enough in our treatment of the Japanese.
I don't believe, after Hiroshima we would of gone through with the invasion of Japan. We would of tightened, if anymore was possible, shipping. Japan would of starved, and what little industry/fuel would not of been able to produce any anti-aircraft threat. After that, Curtis LeMay (God bless him) would of just burnt, blown, roasted and vaporized every major city.
The Japanese didn't not surrender because they wanted to, liked to, were glad to, or were tired. They knew, bone deep, that is was surrender or they would be no more.
