Russia annexed Finland as war reparations after the Finnish war. Sweden had problems with Russia well before that, but I'd say that most of the modern Scandinavian russophobia stems from this event.
Well yes, but guess who annexed it first from Russia? (yes it was Sweden, if you want to talk history)
"From Russia"???
How? It had never been part of Russia.
Finland was part of Sweden since 1249. What are you talking about?
