It is also very likely that Hokkaido and the eastern half of Honshu would have been invaded by Soviet forces (at our explicit invitation) resulting in a situation parallel to East and West Germany and North and South Korea. Instead we in the west had the enormous human talents of the Japanese, pacified and focused on technological innovations for the benefit of the world, and a military base of operations off the coast of Asia, all to ourselves.
Great additional point, again one that you have to know your history to understand. Most people don’t.
