Can you tell me what, exactly, you mean? I am not familiar with your terminology. I have no plastic additions, last I checked.
The term 'plastic' is used to describe someone who claims an ethnicity/cultural identity other than the one they were born and raised in. They often do this to make up for growing up in a country without a culture or longstanding history that they can feel proud of so they link themselves to another country to make themselves feel more interesting and 'ethnic'. They are often found to have outdated cartoonish ideas about the land of their ancestors.
Such people are more often than not found in the colonies of Australia and the Americas.
Don't you realize how difficult it would be for the US to intervene at the time? Now, no, back then, yes. Britain was much CLOSER!!!
Best scenario would have been Britain and France attacking Germany right after the Polish invasion, with US backing them up ASAP.
1)England had only a small regular army
2)the only way to get forces into Poland was via the North Sea which the German navy and Luftwaffe were strong enough to prevent.
3)most French and British generals thought the Poles would be able to defend themselves better than they did, and that the Germans would wear themselves out attacking the Maginot line.
4)if it all went awrong Germany would be masters of Europe entire, not just the continent.
