Churchill committed to supporting the Soviet Union after Germany invaded it in 1941. The immediate reasoning was that the enemy of an enemy could be a necessary ally. By 1943, the discussion has him confronting questions about spheres of influence. His 1946 warning about the Iron Curtain marks the later deterioration of that relationship. The wartime commitment is judged to have paid off for the struggle against Germany without resolving the political conflict that followed.
