Well, he is a comedian
Soviet-Finnish War a.k.a. the ‘Winter War’ started fueled by territorial disputes.
During the interwar period, Finland took a hostile position against USSR developing plans to seize Soviet Karelia. Soviet leadership was concerned with close cooperation of the Finnish ruling circles with Nazi Germany including that in military area (weapons’ supplies).
Soviet-Finnish border ran only 32 kilometers from Leningrad making the Finnish Gulf and the city extremely vulnerable to a possible attack. Despite the non-aggression treaty, Soviet leadership had no doubts that a great war with Nazis was coming and within this context Finland was viewed as Germany’s probable ally.
After Nazi Germany had invaded Poland on 1 September 1939, Soviet leadership was attempting to make a deal with Finland to move its border from Leningrad to strengthen the safety of the city and the country’s northern parts. In exchange, Finland was offered a territory in Soviet Karelia twice as large. All Soviet suggestions were declined.
The Winter War resulted in the defeat of Finland. According to the Treaty of Moscow signed on 12 March 1940 Finland ceded considerable territories to the Soviet Union. After the Nazi attack against USSR, Finland joined Hitlerites intending to revenge.
