I recently finished "Oliver Stones untold history of the United States" on netflix.
It has a leftist bias but being a leftist myself, I like that.
I always knew the Russians played a big role in Germany's defeat, but I never realized how big. I also never realized the role they played in bringing about the surrender of Japan.
A couple of notes: There are twelve episodes, but, unless this has been corrected, the ones labeled 11 and 12 should be 1 and 2. And episodes 1-10 should be labeled 3-12. Also there are several segments that appear to have been repeated verbatim in more than one episode. It appears to me that this was ch done for emphasis but was rather due to sloppy editing.
