First off, there's no denying this is a touchy subject. We can joke around about Pearl Harbor if we wanted to, because Zeroes aren't going to be flying and attacking the base in any of our lifetimes, but nuclear weapons are still a threat to humanity (or so we're told). With that said, I hope no one will get hot-headed as seen in the past.
Now...
I defend the use of the atom bomb, as I do believe it seriously saved lives. I'm not sure, but I believe in many instances more persihed in American and British firestorms than in the bombings of Hiroshima and Nagasaki on the 6th and 9th of August.
Had Opeation Downfall ensued, apart from battle between uniformed armies, would the civilian population really have rushed foward to sacrifice their lives? While the Kamikaze attacks paint one picture, a series I watched the other day had interviews with several veteran aces, including Saburo Sakai, who said that generally, most pilots did not really want to sacrifice themselves, but they followed orders. If a trained serviceman was unenthusiastic about giving his life, would the civilian population really flood foward?
Also, while much of the IJA on the Japanese mainland was well trained and equipped, could it have been an instance resembling the Gulf War II (Iraq's current state)? Where the Republican Gaurd was a fanatical and dedicated force, however, as American forces rolled in... nothing.
Could the IJA really have put up a resistance strong enough to inflict casualties heavy enough to make America reconsider its invasion? Japan, in rough contrast to Western Europe, is very rugged and defendable land - land ill suited to armoured vehicles, and excellent for a retreating army on foot. Criteria that matched Japanese forces well.
I think I've already run off on a tangent, and I'm quite tired. I think I'll turn in and continue this mess of a topic tomorrow when I haven't lost all mental focus.
