Look, dig out your school book if you want. Most school history books are junk, but you have to start somewhere, I know.
The point is, the Japs may have been beginning to talk about surrender, but the ONLY surrender that was acceptable to the Allies, after the Japs intentional infliction of genocide and cruelty in Asia, the sub continent and the pacific, was unconditional.
And this the Japs refused to do. Until they realised they WOULD be wiped off the face of the map.
Sure, you can argue that the Allies were too harsh in their demands for unconditional surrender. But then, they were dealing with monsters, and you can only treat monsters one way -BOMB THEM TO f*ck.
