World War Two: Behind Closed Doors

I know WWII pretty well although I am no Ian Kershaw or Stephen Ambrose. (R.I.P) I am a wannabe historian that knew very little to none of these going-on's behind closed doors. I won't give anything away as this should be seen to understand even more about how the Europe was divided up by the allied powers. Granted by the time most of these events happened it was pretty much sewn up that the Nazi's were going to lose it was just a matter of time. It surprised me although I knew already how very arrogant all of these men (FDR, Churchill, & Stalin) were being while millions were dying. I knew how Poland suffered so much and even knew some of the Katyn massacre, although the extent of the cover-up truly was disgusting & repulsive that which Stalin & Soviets did. Although there is propaganda now, I didn't think I've ever seen it used more or as effectively as it was during WWII on all sides of the conflict. Back to Poland. Poland was so mis-treated that I don't really think people know just how bad it was for them. This documentary although focusing much on the leaders should have been subtitled something about the abuse Poland received by everyone especially the Nazis, & the Bolsheviks. This is a much watch for all those interested in the truth especially wannabe historians (like myself) & real historians alike as this is information that is very new & seems to cover someone unfortunate & terrible truths to go w/those we already knew.
