The Confederacy ceased to exist.
Finland continues to exist when the USSR’s original plan during the Winter War was to conquer them. Finland won the right to continue to be a sovereign country.
Finland was ruled by the Russians for a century before the Russian Revolution, which gave the Finns an opportunity to achieve independence for the first time in centuries. (Prior to Russian rule, Finland had been ruled by Sweden for several hundred years.) Millions of Ukrainians were starved to death in the Holodomor of the 1930s. In perspective, it was the Ukrainian equivalent to the Holocaust or the Potato Famine.
The Baltic States were under the Tsarist and later the Communist thumb except for a short independent period from 1919 to 1940. These nations were subject to brutal executions and deportations under Stalin, who tried to Russify these countries.
As for Poland, that nation suffered under Russian, German, and Austrian oppression for over a century, followed by genocidal Nazis and brutal Communists over a fifty year period from 1939 to 1989. Stalin took eastern Poland, compensating Poland by giving them formerly German Pomerania and Silesia.
At the end of World War II, Romania lost Moldova, which is ethnically Romanian, to the USSR.
Russia's western neighbors have plenty of reasons to fear and hate that nation. Even Sweden, which stayed out of both World Wars and the Cold War, wants to join NATO.
