Actually a lot of Finns travel to Russia on a regular basis and vise versa. In fact if im not mistaken the relations between the 2 countries has gone up in the last decade. Also I dont think that Stalin wanted to actually capture Finland. Finland border was at the time about 40 miles from St. Petersburg, Russias second largest city. Stalin wanted to push the border back and he did, from 40 miles to 400 as a buffer zone for protection. This ofcourse can be desputed. But after the war the soviets liberated Finland for Nazis and never took it over nor did it become communist same thing with Austria.
