A Ukrainian Holocaust survivor has stated that Russia is waging a "war of extermination" in Ukraine, drawing comparisons to the actions of Hitler during World War II. The comments come as Russia's actions in Ukraine are being compared to the Holocaust by some, with references to historical events such as the "Holocaust by Bullets" in Ukraine and mass shootings at Babyn Yar. The situation has sparked discussions about the lessons of the Holocaust and the dangers of genocide, with some noting that the lesson of "Never Again" may have been forgotten.
