I would probably agree with the broader outcome of your argument, but I don’t think rationalizing the violation of territorial sovereignty through “cultural ties” is a very strong foundation. If the rule of law is to exist, borders have to be respected - they are known, measurable. Cultural ties has a long history of rationalizing invasion, and is demonstrably (from historic examples) a very nebulous and qualitative argument that can be molded to fit needs of the invader. Just because we speak the same language or have a similar hat style doesn’t mean I want your government controlling my town and its resources.
