But to provide support to Finland in the winter of 1939-1940 was not at all inconsistent with waging war against Nazi Germany.
Recall that back at the start of 1940 Stalinist Russia was Hitler's *ally*--using its control over local CPs in the West to try to undermine the British and French war efforts, supplying Hitler with immense amounts of raw materials very cheap, and trying to conquer small nations: eastern Poland, Lithuania, Latvia, Estonia, Finland.
Thus Finland's struggle to keep from being overrun by Stalin seemed then to be the *same* struggle as the struggle to reverse the joint Nazi-Stalinist conquest of Poland. Why not aid Finland in its fight against the Nazi ally--especially when aiding Finland would also cut off some of Germany's key iron ore supplies?
