It was the lunatic emperor that prolonged the war and forced us to drop the two A-bombs. The consensus among the Japanese military commanders was to sue for peace prior to the first atomic bomb being dropped. Also, Russia didn't get involved until they knew the Japs were done. America might dominated the pacific.
Imagine how productive Germany would have been without allied strategic bombing. Example...Germany was working on advanced military technology that NEVER made it to the battle field. Why? Because we destroyed their production and R&D facilities. Germany made the ultimate blunder by fighting a two front war. Invading Russia proved too costly, but D-Day was what saved countless lives. Imagine what Germany would have done without having to defend against an allied invasion in the west. The eastern front would have been a different story. Again, America won this theater too.
