Relationship With Russia
Finland has had a… contentious relationship with Russia, to say the least. Finland was annexed in the early 1800s by their overbearing neighbor, and they were ruled until the Bolshevik Revolution when they declared independence from Russia. They maintained their independence since.
As you can see from this comic from the early 20th century, Finland didn’t have too great an opinion of Russia, envisioning them as a pack of wolves nipping at their heels.
