The document, viewed by JNS and titled “The New Crusade: Sons of Tarrant,” appears to reference Brenton Tarrant, the gunman who killed 51 worshippers at two mosques in Christchurch, New Zealand, in 2019. The manifesto contains neo-Nazi, antisemitic and racist rhetoric and praises mass killers, including Tree of Life synagogue shooter Robert Bowers and Adolf Hitler.
