Antisemitism remains a pervasive challenge throughout the West, influencing a variety of violent and non-violent extremists across the political spectrum. In the United States, Jews are the targets of the majority of hate crimes committed against any religious group. While the extremists behind many of these attacks come from many movements, they are all united by a common antisemitic worldview. From Islamists to neo-Nazis and white supremacists, from black supremacists to far-left extremists, each has incorporated antisemitism and antisemitic tropes as key components of their ideologies, and as a means of mobilizing followers to perpetrate acts of violence. 

Article: Intersectional Antisemitism in America

In this article for Tablet, Program Director Lorenzo Vidino explores the belief that Jews are unique agents of evil, secretly manipulating world events is the common denominator in virtually all forms of extremism present in America today. It is not entirely a new phenomenon, as cross-ideological pollination of antisemitism is a centuries-old cancer. But because of the web, we have fully entered the era of intersectional antisemitism.

In this climate, it is not surprising that, in 2019, 60% of all religiously motivated hate crimes were against Jews. The federal government, law enforcement agencies, and Jewish communities throughout the country understand the problem, and know that there is no easy fix. A good place to start would be with large-scale educational efforts: A 2020 national survey of millennials and Generation Z showed that 63% did not know that 6 million Jews were murdered in the Holocaust. We also need to see enhanced security protecting Jewish targets, and increased focus on the antisemitic content that is tolerated by social media platforms. These endeavors are necessary to begin to stem the tide of the growing American problem of intersectional antisemitism.

Report: Antisemitism as an Underlying Precursor to Violent Extremism in American Far-Right and Islamist Contexts

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.  Antisemitism, as a belief and world-structuring theory, can at times serve as a gateway issue for individuals into further radicalization to violent extremism. Nonviolent and violent iterations of the same extremist milieus often share antisemitic views as central elements of their belief system, and thus antisemitism constitutes a linkage between activist and violent extremist segments of the same movement. 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.



During the summer of 2020, Program Director Lorenzo Vidino worked with the London Times on an investigation of the global charitable organization Islamic Relief Worldwide (IRW), uncovering years of antisemitic and pro-Hamas social media postings by various IRW board members and top leaders. In an interview with The Times, Director Vidino highlighted how comments made by multiple leaders showed, "a problem at the highest levels of IRW that is not confined to one rogue individual... Such conduct should raise red flags for every national government and civil society organisation that partners with and funds Islamic Relief..."The joint investigation culminated in the entire board of IRW resigning, and led the U.S. Department of State and the governments of Germany and the Netherlands to stop or pause and review funding the organization.
