This is a fascinating piece of 1952 footage featuring former US Ambassador to Poland Arthur Bliss Lane discussing a Big Lie put over by the Soviets in 1943 concerning their 1940 massacre of thousands of Poles in what is known as the Katyn Forest Massacre.
I'm not sure the facts come through clearly in this short exchange, but the basic outline of events is as follows. The Germans uncovered mass graves containing thousands of Polish officers in Katyn Forest near Smolensk in April 1943. The Soviets blamed the Germans for the massacre. The Germans blamed the Soviets. The Soviets -- our bosom allies led by "Uncle Joe" Stalin and appeased at all costs by FDR and Churchill -- were, in fact, guilty. The US and British governments under FDR and Churchill not only accepted this Soviet Lie, they amplified, supported and perpetuated it, and for most of the next decade -- even in the face of overwhleming evidence to the contrary. I discuss this notorious cover-up and its deep implications at length in American Betrayal, presenting it as a significant marker in what was an accelerating pattern of Western complicity with Soviet crime.
It speaks to American Betrayal's subtitle: The Secret Assault on Our Nations Character.
