I recall seeing a US Army map of Germany in the 1970’s that still showed the 1937 borders. I don’t believe the issue was finally settled until Germany and Poland signed a treaty after the fall of the Berlin Wall.
How did that turn out? Did Poland end up with what were German lands before ‘37?
Ike was right that Japan was already defeated. What he was wrong about was that they had no intention of acting like it. Dropping the bombs was necessary to force their surrender and eliminate the need for invasion.
