But even putting the contested places aside, what do you do with territories that just aren't countries, but aren't properly part of another country either? Like those British Colonies that haven't become independent, but aren't part of the "United Kingdom" either? Like the British Overseas Territories or closer to the UK the Crown Dependencies? They aren't part of the UK like Scotland is (for now at least), but self-governing possessions of the British Crown.

Or Puerto Rico for that matter with the US. Right now it's on the list as "country".
