It's quite incredible to see what kind of nonsense this series feeds to the audience. If you look at the map of Europe presented in this series (e.g. the one depicted in the first episode when presenting German territorial losses after the treaty of Versailles), especially looking at Poland, you will see borders that have never been a reality. It's a combination of the present and past borders with a fake East Prussia region put ontop of the current Polish borders. It is ridiculous to see this series not being able to get such simple facts straight.
