The book A History of Central Banking and the Enslavement of Mankind touches on this a bit. I'm sure there are more complete histories, but this will give you a good idea of the scope of the issue.

Basically, Stalin turned against the Zionist/jewish bankers of the west at the beginning of his reign. Zionism and Bolshevism were basically a jew vs. jew fight that was seen as determining the future of the international jew. At the beginning of WW2, Zionist jews declared war on Germany (economic and ethnic cleansing in Poland, etc., first, then a military war later.) Stalin was against the Zionists and their banks, so Hitler allied with him. He made a deal with the devil, and knew Stalin (another bloodthirsty jewish tyrant) could not really be trusted. Stalin eventually sought loans from the western jewish bankers and was brought back into the fold.
