Antisemitism as an Underlying Precursor to Violence Extremism in American Far-Right and Islamist Contexts

By Alexander Meleagrou-Hitchens, Bennett Clifford and Lorenzo Vidino

Antisemitism is pervasive throughout several categories of American extremist movements, both violent and non-violent. American extremists incorporate antisemitic tropes and narratives in every level of their worldviews, using them to help construct “us/them” dichotomies and wide-sweeping conspiracies that are essential to their movements. • During the past several decades, the American extremist movements that have been among the most violent—specifically, far-right and jihadist groups—have used antisemitism to target Jewish people, Jewish houses of worship, Jewish community institutions, and Americans supporting the Jewish state of Israel. …. • Several case studies of violent American extremists, representing far-right and jihadist movements respectively, demonstrate that antisemitism can be an integral part of American extremists’ progression through the radicalization process and in justifying terrorist attacks. • Based on this report’s finding that antisemitism is foundational to multiple violent extremist movements in the United States, counter-extremism practitioners and scholars may consider incorporating antisemitism as a diagnostic factor for extremist radicalization.
