I watched a Chinese movie called “NANJING!” this past weekend. You can guess what it was about, and the Chinese view of Japan’s behavior in WWII.
The unspoken truth is:
1) The Emperor needed the USA to drop the A-bombs. It gave him the cover he needed to overcome Tojo and the fight-to-the-death faction of general running the Gov’t
2) The Japanese thank God it was the Americans and it wasn’t the Chinese who developed the A-bomb in WWII, because Japan would not exist today if that had been the case.
Imagine if the war had dragged on until Mao took over China, and then he sent millions of screaming Chinamen into Japan, along with the Soviets.
This fact cannot be overstated, if the Emperor were to be assassinated, all bets were off.
