On #3, it would not have been the same deaths. Russia hated Japan and would have genocided the Japanese by the millions, torturing, starving, brutalizing, slaughtering them. Russia would have conquered and enslaved Japan for the next half century. Instead the US occupied Japan and forced cultural changes upon them, which resulted in Japan becoming a democratic, peaceful economic power and tremendous contributor to the global economy and both global and regional stability.
