All this forced Finland March 12, 1940 to agree to conclude with the USSR Moscow Peace Treaty. For its part, the Soviet Union also was not interested in prolonging a war that could escalate into a large-scale confrontation with the West. For the Soviet Union, the skillful use of the benefits of Germany's armed struggle with Britain and France, the neutral position in the global conflict is the best option. Under the terms of the Moscow Peace Treaty, the Soviet Union received the entire Karelian Isthmus with Vyborg, the area north of Lake Ladoga, plus the territory in the area Kuolajarvi and the western part of the peninsula fish. Even the Soviet Union has acquired in lease for 30 years, the peninsula of Hanko (Hanko) at the entrance to the Gulf of Finland. The distance from Leningrad to the new state border increased to 150 km. "Mannerheim Line" was destroyed.
