During the Palmer Raids of 1919 and 1920, many suspected radical leftists, a number of which were communists, were deported to Finland, a country at war with the Soviet Union. The former Assassin Nikolai Orelov believed that his wife and daughter were among those sent to Finland and were killed by Finnish soldiers.
During World War II, Finland was invaded by the Soviet Union and briefly turned to Nazi Germany for assistance. Following an armistice with the Soviets in 1944, Finland expelled the Nazis from the country, leading to the Lapland War.
In the middle of the 20th century, Finland created the Utti Jaeger Regiment, a centre for training the Finnish Army's special forces. Juhani Otso Berg was a member of the regiment, but quit to become a mercenary to acquire money for his daughter's treatment.
