>>17860488 (OP)Some of these other comments are missing the mark by a bit. A full year off the end of the war would have greatly reduced the Soviet footprint in East Europe. There may not even have been an East Germany, especially since the Soviet army would never have made it to Berlin for the Great Raping and Looting. That would have been a huge loss of their stolen brain and industrial loot from Germany, plus the fact that Germany would have had so many more Germans alive and being productive krautisms
FDR would have been in much better health for whatever Yalta-equivalent negotiations that would have ensued, so Stalin would have got less than he did. The Soviets wouldn't have been positioned to occupy the Kurels, either. Japan would have fallen slightly faster with more resources available to pour into the Pacific theater. These are seriously significant factors that would have impacted containing the Soviets throughout the entire Cold War.
And, like it or not, there would have been at least one million (if not two) more Jews alive. That would also have impacted Jewish brain trust & wealth while slightly reducing some of the worst concentration camp horrors. The highly traumatic repercussions of the Holocaust stories & evidence would have had less influence over Western guilt ... if not in the first couple of decades than maybe not so strongly for so many decades. Not insignificant.
Overall, it would have made some huge differences. There is an entire tsunami of butterfly effects that would be virtually impossible to map out and determine with any certainty what today's world would look like. Changes in world political alliances alone can barely be imagined, NATO and the United Nations would be vastly different or maybe not even have happened at all in any form we see them today.
