Another example of "man's inhumanity to man" posted on YouTube is circulating in the Ukrainian community.
Explanation at the U.S. Holocaust Memorial Museum site:
During the Lvov/Lemberg [sic] massacre of June, 1941, the retreating Soviets killed several thousand mostly Ukrainian nationalist prisoners who were being held in several prisons throughout Lvov [sic]. The Germans blamed the massacre on the Jews and used the NKVD's atrocity as propaganda to incite a pogrom in which over 4,000 Jews were killed. A further 7,000 Jews were murdered by the Einsatzgruppen.
It keeps happening over and over again because humanity refuses to learn from history. Very sad.
