Good points.
Regarding USSR, they did declare against Japan and deploy somewhat. I was not certain if USSR was wanting to open a new front a-la Berlin in Japan too... so I did not include it.
Regarding the Emperor, to the Japanese People and their Bushido, Surrender is not an option. And the mindset was the Emperor is Divine and to even consider signing Terms with the USA or anyone is not exactly supported at the time.
Sometimes I wonder if our own Embargo against Japan caused them to strike south for the oil, rubber and eventually to Pearl in a attempt to smash our Carriers. (That was the real prize...) they also happened to leave the tank farm at Pearl alone more or less. If they destroyed that too... our ability to make war on the Pacific would be limited to the West Coast only.
I think Embargoing Iran now is driving them to war. I myself over the years have been a very strong die hard Hawk for a proper war for the reasons deemed.. reasonable. !
Now I am beginning to see a Nation that is not truly at war today or any time into the future.
Our enemies are going to hit us where it hurts and it only hardens my resolve not to quit.
Those who fail to properly teach history to our Children will doom our Nation due to ignorance of lessons bought and paid for by our fathers and their father's blood on the Tree.
