12 mins in and I'm ready to give up. Except for the footage, I didn't really want to watch any more of it. Not sure where these so-called scholars interviewed come from but their knowledge of wwii seems pretty limited. If this was produced in 1975, I'd probably not be offended but c'mon. The non-agression pact was signed in august 39 and just a few weeks later, germany invaded poland from the west and the russians invaded poland from the east. Clearly they had intentions to divide poland though during and after the war the american press underplayed the soviet's role. Two years later germany invaded the rest of poland and russia but not before massing huge amounts of personnel and equipment along the polish frontier. When the germans were asked why, they replied that it was necessary to keep this material and men away from british bombers, though at that time, the british didn't have dominance in the air over europe or mastered precision bombing. It's impossible to say what stalin thought of hitler exactly but after the invasion, it's been reported that stalin was incredulous that hitler would invade that he became almost unhinged to the point of not being able to make any decisions in the early days. From all eyewitness accounts at the time, and contrary to the film, stalin probably thought he had in hitler a familiar associate in thought, perspective, and actions. That's just one of many mistakes in the series. Yes, I did watch it all but only for the footage.
