I'm pretty sure we never did. Some people still view it as the best way we could have ended the war...of course, those are the people who don't realize we had already all but won. Yeah, this is something we should do, but we never will. To do so would be to admit that in the "Great War" led by "The Greatest Generation," we committed "The Greatest War Crime" ever. This country is far too deeply rooted in the idea of American righteousness to ever apologize for something like that.
