Majority of Finns wanted their country to stay as part of Russia in 1917, and this is why a civil war started in Finland.
Germany, Sweden, Norway, Denmark, Italy and UK supported Finland in 1939. This is similar to the process today, when NATO is enlarging to the borders of Russia. Finland was then just like Ukraine now. It is our [Russia’s] territory.
A "documentary" repeats at least ten lies about the Winter War and Finnish-Russian relations.
Finland did not get support from Germany. Finland was supported by the other countries mentioned, but only after the war started. This has nothing to do with NATO enlargement. When the countries of Central and Eastern Europe applied for NATO membership after the dissolution of the Warsaw Pact, it was of their own free choice, through their own national democratic processes, and after conducting the required reforms. This was done through debate, in peacetime conditions, and in a transparent way.
Ukraine is not part of Russia, but recognised in international law as a sovereign nation state, with its own flag, nationality, language etc, just like Finland was in 1939.
