You would have to show me documentation of were the Emperor was ready to surrender, actually quite to opposite is true, the battle of Iwo Jima was a stalling tactic so the Japanese could better prepare for homeland defense. The troops on Iwo Jima were ordered to hold out as long as possible to allow for this homeland defense. Of the 21,000 japanese solders on Iwo only 216 were taken prisoner, the American forces lost 6,821 with 19,217 wounded in the fiercest fighting of the Pacific theater. With this many casualties taken on both side on an Island only 8 square miles, one can imagine how many casualties would have occurred had the Japanese defended their homeland as fanatical as those who defended a small island.
I can see you have never been in the military, one does not sign up "to Die" but to defend one's country, and I am angered that you would soil the sacrifice given by so many of those young soldiers. Many are killed in war who have no intention of dying, regardless of what you have been lead to believe the Atom Bomb did save hundreds of thousands on both sides.
If they are not signed up to die, then why do they do it?
"It is the foremost concern of a Warrior to keep death in mind at all times."
-Taira Shigesuke, "Bushido Shoshinshu"
Beginner's Way of the Warrior (Translated by Thomas Cleary as "Code of the Samurai")
It is my firm belief that even commoners like us should accept the fact that death could come at any time, and live each moment as the last. This applies even moreso to professions which involve great danger, such as being a soldier.
And no, I have never signed up for the military; I cannot, for I am frail and underweight. (Besides, I'm not a soldier; I'm an intellectual.)
Besides, cities are civilian places. It is completely dishonorable and cowardly to attack civilians, and I call the ones who ordered the bombing of Hiroshima and Nagasaki cowards and without honor. (NOT the ones who actually delivered the bomb and flew the planes carrying them; they were just following orders.)
