  1. Had Japan not surrendered during world war two, the Allies would have possibly implemented "Operation Downfall" a planned assault on Japan. One military planner estimated that as many as seven atomic bombs would have been ready for detonation for the invasion, which was scheduled for November 1, 1945. Had this plan been realized the number of dead and wounded of WW2 would have been much more than appears on this list.
