“Yeah, well, how did that alliance with England and France work out in 1939?”
Not very well. They declared war to Germany, but French army sat on Maginot line without firing a shot, and England try to get in Europe ended with the catastrophe at Dunkirk. One year later, France was occupied and Germans launched the blitzkrieg against England. Not a single Brit or French soldier ever reached Poland territory.
Meanwhile, Poles saved Britain’s bacon in the ‘Battle of Britain’, fought in all theaters (Monte Cassino). And what did they get? Sold out to Uncle Joe.
