have still won the war just with significantly more casualties. The various strategic bombing analysis that I have read have all found it to have been marginal including the official Air Force study. I would have still done it and I don't apologize for it, but I'm skeptical of what it truly accomplished.
America clearly and decisively won the Pacific war, but not by torching Japanese cities. Again, I don't apologize for it and would have done it, but the consensus of military historians like Hastings again is that it was marginal in the end.
America's men and arms did much to win the war. Not through what its enemies were doing though. In other words, the war wasn't won by dehousing or incinerating civilians, although again there was plenty of it by the allies. That's the difference.
