For 70 years the word Katyn is an open wound in the memory of the Polish nation. It can be healed only by the victory of truth against lie. This battle lasts since 1943, when Goebbels wrote in his diary on the day the Germans were retreating from Katyn: with no doubt the Russians shall blame the Germans for this crime. The Nazi ideologist guessed right because there was no difference in the essence of these enemies. During the trial in Nurnberg the Soviets tried to accuse Nazis of the Katyn massacre but the allies didn’t dare to confirm the fake, and it was nonsuited due to the “lack of evidence”.
