Again, there is no evidence that the Japanese were ready to unconditionally surrender prior to dropping the A-bombs. It was difficult to do so afterwards, and the US was ramping up production of more plutonium based bombs for a further bombing campaign. It took the personnel intervention of the Emperor, and the collapse of an Army coup, for an unconditional surrender. It doesn't matter what various US military leaders thought - what mattered was what the Japanese thought - I mean Ike wasn't going to surrender for the Japanese. And there was no desire on their part to unconditionally surrender. Why would they? They felt that they were in the position to make an invasion difficult enough to bog the war down for years, and with the war won in Europe, the US public would lose the will to keep fighting. Yes the war was destroying Japan, but much less so in their mind that surrendering and having US troops in Japan, which they felt would be the end of Japan as a nation. The continued deaths of Japaneses citizens was a price the leadership was more than willing to pay. The Japanese wanted a cease fire, with no placement of US troops in Japan.
