That's one way of twisting the figures to suit your agenda.
There's no chance that the Japanese are killing 10000 per day in August 1945. As stated by VT above, at Yalta the Soviets had already agreed to enter the theatre after the war in Europe was finished. In fact they dished out an absolute hounding to the Japanese and destroyed a million strong army in the space of two weeks.
Regardless of the rights and wrongs of dropping the bomb and there's arguments for both, you're trying to justify the vaporizing of over 150000 civilians in order to save a couple of thousand lives on the battlefield.
Bet this post makes me worse than Stalin though, amarite ?
