Did all the land lost by Finland in the Sufen War later return to Finland?

The land lost by Finland in the Sino-Finnish War never returned to Finland. Finland was accepted as a vassal state by czarist Russia in the early17th century. After the October Revolution, the Finnish government declared independence. Since then, the relationship between Sufen and Finland has been very weak, and the Finnish rebels supported by the Soviet Union were eliminated by the Finnish government. Finland is close to the Soviet capital. Stalin was worried that Germany would use Finland as a springboard to attack the Soviet Union, so Sufen signed a non-aggression treaty, which was confirmed to be valid for ten years after 1934. 1938, Su Fen negotiated again, hoping to fight Germany together, but there was no substantial progress in the year-long negotiations, but the situation in Europe was already very serious.

1939 At the end of August, the Soviet Union and Germany signed a non-aggression treaty, secretly dividing up countries in Eastern Europe, and Finland was allocated to the Soviet Union in the treaty. In early September of the same year, the Soviet Union and Germany surrounded Poland and carved it up. At the same time, Sufen negotiated again, and the conditions put forward by the Soviet Union in the negotiations were rejected by Finland on the spot. In June 5438+065438+ 10 of the same year, Finland offered a condition of less relative benefits, which the Soviet Union refused to accept.

Subsequently, the Soviet Union launched a war and abolished the treaty, which made the relationship between Sufen and Finland deteriorate completely. The Soviet Union began to attack Finland in 1939. Due to the stubborn resistance of the Finnish people, the war continued until 1940. In this war, Sufen suffered losses, Finland lost part of its territory, and the Soviet Union lost the support of international public opinion.

Due to the disparity between the two sides, the Finnish government was forced to make peace. 1940 In March, Sufen and Sufen signed a peace treaty in Moscow, and the two sides formally stopped fighting the next day, ending the Sufen War. The Soviet-Finnish war lasted more than 70 days, with 200,000 casualties in the Soviet Union and more than 68,000 casualties in the Finnish army. Finland was forced to accept the Soviet Union's request, ceded 10% of the country's land, lost the land around Lake Ladoga, including the ceded northern Chemo area (which still belongs to Karelia in the Russian Federation), and leased the Boccara area 20 kilometers west of Helsinki to the Soviet Union for 50 years. The Soviet Union achieved its strategic goal and won a buffer zone for the Soviet people near Leningrad. Even if there is a war in the future, the Soviets will arrive in time.

Moreover, Stalin's extreme national migration policy after World War II completely changed the national structure of Karelia. According to statistics in 2002, Russians in Karelia accounted for 76.6% of the total population, while karelians only accounted for 9.2% and Finns only accounted for 2.0%. Many Finns also admit that it is almost impossible for Finland to recover Karelia.
