The work of the prominent Finnish historian Mauno Jokipia is devoted to the Finnish-German military rapprochement and cooperation at a relatively short stage in European history (March 1940 - June 1941). Contrary to the widespread concept of a "rafting log" about Finland's allegedly involuntary entry into the war against the USSR, the solid documentary basis of the study allowed the author to come to the conclusion that Finland had consciously and consistently approached Hitler's Germany with the aim of attacking the Soviet Union.
