Worked out pretty well for Finland, has it not?

Finland inflicted a serious military victory over ussr, actually had a possibility of Allies joining in Winter War, and fought with ussr in 1941-1945. After all that it got its neutral position, not only by ceding some land, but actively resisting. Meanwhile Baltic states lost their sovereignty for 50 years.

No, it hasn’t.

They lost a large chunk of land and every male still needs to spend one year of their life defending their country.
