A consequence not mentioned is that Joe Stalin, a good reader of tea leaves, was on the verge of declaring war on the Japanese. Had this happened and a soviet front had actually been opened, we (U.S.) would probably have been obligated to share the partition of post-war Japan with the Soviets. How such a partition may have changed post WWII geo-politics in the Pacific region would be difficult to predict.
Interesting thought as to how the Russians would have treated the Japanese had they too invaded.
Bet Old Joe wouldn’t have been quite so benevalent.
