an attempt to take on Germany at that point in time would have resulted in more than a loss of face. The casulties would have been horrendous and the defeat absolute. I guess you didn't major in military strategy?
Sadly, that's part of war. That's the reality. Should Britian have taken on a responsibility they couldn't handle, ie: the declaration of war on Germany? Probably not. Without a concise plan, history has pointed the finger at Britian for declaring and not rendering.
Harry you are just bashing poles here after their country was heartlessly invaded. Nazis wanted to take every single pole, no matter what ethnicity, and put them in the gulag style KZ. How can you be so heartless?
