No one really wants Finland.
If Russia wanted Finland, they could have had the whole kit and kaboodle in 1939-1940.
Belaya Smert and his buddies kept the Soviets out of Finland.
Seeing how Putin’s invaders are currently doing, pretty sure Simo’s descendants wouldn’t have much problem.
Actually, the Finns want Finland, and they've never been shy about it. The Soviets also wanted Finland, which is why they invaded. But after losing something over 100,000 troops and a couple thousand armored vehicles in a matter of months, Stalin decided he wanted Finland less than he thought. The Finns still wanted it, and got to keep most of it, although they had to give Stalin his pound of flesh to get an agreement to end the fighting.
Guess the world will see who really wants Ukraine...
