Ah, look! A revival of the old thread aiming to "clear things up once and for all". That usually does not go very well

Finland is an odd situation. It's half in Scandinavia, half in Russia. It was occupied by both Sweden and Russia and contributed to both their empires. Linguistically, they're connected to neither.
I guess it depends on how you define the word occupy, but I never cared much for the saying that Sweden occupied Finland as it derives from a modern day perspective where there exists two states and I feel that it to some extent belittles the Finns. I would say that for a good 600-700 years, Finland
was Sweden. In fact, after the 1808-09 war against Russia the western part of the old kingdom, traumatized by the conditions of the peace treaty, began a transformation searching for a new identity (the one we're living with now), while the eastern part of the old kingdom, now being a part of the Russian empire, defended the old traditions ardently against Russian influence and consequently was being more swedish than Sweden, socio-politically speaking.
Historically half in Russia, as in historically part of Russia. It's policies have never been exclusively western because of that Western connection. The second half of the 20th Century they took a far more neutral role than any other Scandinavian country because of the pressure/conflict with the Soviet Union. I didn't mean they aren't Scandinavian, just they have external concerns.
It's also a language that's entirely unrelated. Swedish, Danish, and Norwegian are almost mutually comprehensible.
If you limit your perspective to the cold war era you will find a lot of policies attempting to appease the relationship with the Soviet Union but the state of Finland is by no means an eastern country. If you are talking about the province of Karelia then yes, that is half western, half eastern.
Finnish is not a germanic language that's true, but geographical proximity and historical bonds have resulted in a number of elements linking Swedish and Finnish languages, so it's not completely unrelated. On top of that you have a minority of Swedish speaking people in Finland and Finnish speaking people in Sweden and the support of their languages by law, so even solely linguistically speaking you cannot exclude Finland from Scandinavia.
Except that Finland is not a part of Scandinavia. It's a part of the Nordic countries.
This is an English speaking forum where the term nordic makes little or no sense. To the rest of the world it's Scandinavia, and why not? It includes the geographical, political, ethnical and linguistic perspective and holds least possible considerations.
