I'm interested in watching a WWII documentary which talks mainly about the politics, economics, geography, causes, etc. about the second World War. One that explains Hitler's propaganda, how was Stalin's governmet during his era, why did the USA get involved, Charles de Gaulle, etc.

All the ones I seem to find focus way too much in either stories of civilians and soldiers, or military tactics and combat, etc, and I don't really care too much about that.

Thanks in advance.
