They write that the distinction has been blurred in the subsequent decades as the Holocaust was universalised.[8] According to the United Nations, the Universal Declaration of Human Rights was adopted in 1948 because "the international community vowed never again to allow" the atrocities of World War II, and the Genocide Convention was adopted the same year.[9][10] Eric Sundquist notes that "the founding of Israel was predicated on the injunction to remember a history of destruction—the destruction of two Temples, exile and pogroms, and the Holocaust—and to ensure that such events will never happen again".[6] The slogan "never again" was used on Israeli kibbutzim by the end of the 1940s, and was used in the Swedish documentary Mein Kampf in 1961.[7]
