“Finland is pro-Russia so Russia has no real need to take it over. The relations between the two countries are quite close.”
There you go again with yet another outrageous lie used as grotesquely false propaganda. The Finns generally speaking absolutely loathe and despise Russians because of the Russian oppressions and aggressions against the Finns.

Just like Ukraine, Finland is a product of Soviet takeover of Russian Empire. I don’t think if Finland was ever independent as a nation-state before 1918. AFAIK, this territory was annexed by the Russians from Sweden some 200 years ago and locals has actually supported Russian takeover at the time (Swedes has taxed them too heavily).
On the other hand, Finns used last century to build their identity well.
It is one perfect example of self-determination which really worked into a successful nation.
