I mean if you go back 300 years, but then if you go back 1000-1300 then most of England & Scotland starts to look pretty German (Anglo-Saxons, Norse), with England getting significant French & Scandinavian (Norman = French Norse) influence after and tenuously Austrian (Celts) before that... The native British people were completely wiped out at least twice before that, so frankly all sorts of European nations *could* have a claim if Putin rules applied
