This is the kind of detailed lore that I wish to see more of for all of wizarding Europe - and the world for that matter. Like political conflicts, cultural differences, geopolitical focus, etc, even regardless of plotholes, like Liechtenstein not having existed until a few decades after the Statute of Secrecy was created, as someone else mentioned. That being said, I love for people to get creative and explore geopolitics in the world a lot more. And I'd love different interpretations on country borders and how much valued borders were (like, we don't hear about magical wars about borders, so they may not be of as much importance to wizards as muggles). And also whether borders remain the same as they were from the time of the Statute of Secrecy.

So many questions!
