Because as has been stated several times in this thread, they feared the Americans would hang the Emperor. Do you need to be reminded that the Japanese revered the Emperor as a God and that nothing was worse than being disgraced. They thought they had no choice but to fight to the death, thanks to FDR’s murderous unconditional surrender requirement.Anxious to make peace why didn't they just wave the white flag and surrender?
How long would it take for Japan to say: We surrender and will not harm your troops when they come ashore? I think the GI slated for the invasion knew the Japanese better.
Truman massacred all those women and children, then agreed to their only condition. Does that make sense to you?
How is unconditional surrender "Murderous"? I mean he was the man who called for the Pearl Harbor attack.
And as for "protecting the Emporer" I think you are talking about ketsu-go, the strategy of fighting one last decisive battle intended to inflict so many casualties on a war-weary America that it would relax its demands for unconditional surrender and negotiate a peace which would at a minimum, safeguard the Emperor, and potentially preserve the armed forces and shield them from prosecution for war crimes.
That's the alternative you support? Killing as many Americans as you can to support the Emporer, the man who made the call to attack Pearl Harbor, from any charges and letting their leaders walk free from war crimes?
