The part about Czechoslovakia is absolute nonsense. The Czech language has been spoken and written since the 12th century and was always centered in the Kingdoms of Bohemia, Silesia and Moravia. The only reason these kingdoms became part of the Austrian Hungarian empire under the Hapsburgs was because of their loss in the 30 years war. Even so during this 500 year period the Czech language remained. Just like the United Kingdom exists today but you don't say the Irish, Scottish or Welsh no longer exist. Hell they don't even speak their own languages anymore and all speak English. Does this mean they are all just English? Here is a visual history of Europe's borders and as you can see the Kingdom of Moravia and Bohemia are always there. https://www.youtube.com/watch?v=UY9P0QSxlnI Hitler had no right to invade. Moravia and Bohemia also use to have extended borders but lost them in wars and certain marriages of royal families, so do we also have the right to claim land in other countries?
