"Never again" is a phrase or slogan which is associated with the Holocaust and other genocides. The phrase may originate from a 1927 poem by Yitzhak Lamdan which stated "Never again shall Masada fall!" 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.
