Dunkirk wasn’t really in Poland, look it up, and Poland was not an American ally at the time, and part of our NATO alliance.
How weak and submissive, and pro Russian are you?
The French and British had a security treaty alliance with Poland. When Germany and Russia invaded, the British army was chased out of Europe by the Nazis. It was a fiasco.
We have been allied with France and England for more than the last 100 years, and still are today.
Seems like you're hell bent on starting WW3.
