In the context of genocide, the slogan was used by liberated prisoners at Buchenwald concentration camp to express anti-fascist sentiment. The exact meaning of the phrase is debated, including whether it should be used as a particularistic command to avert a second Holocaust of Jews or whether it is a universalist injunction to prevent all forms of genocide. It was adopted as a slogan by Meir Kahane's Jewish Defense League and used to justify acts of terrorism against perceived enemies of Jews.
