Traditionally, antisemitism in the United States was promoted by far-right organizations and movements which focused on propagating traditional antisemitic narratives alleging Jews’ racial inferiority, their control of the financial sector, and their role in global cabals aiming to undermine America and Western civilization. In the last thirty years, however, the ideology underlying antisemitism in the U.S. has come to encompass both sides of the political spectrum. Progressive and left-leaning movements that are critical of Israel’s policies, especially with regard to the Palestinian population, have become linked to antisemitic practices, too.

The U.S. is currently experiencing one of the most significant waves of antisemitism that it has ever seen. Jewish communities are shaken and traumatized.

Jewish and civil rights organizations both in the U.S. and in other Western countries reported a rise in antisemitic incidents following the Oct. 7, 2023, Hamas attack on Israel and the subsequent Israeli military response. The Anti-Defamation League reported that in the first week after Hamas’ deadly attack, in which 1,400 Israelis were killed, antisemitic incidents in the U.S. tripled in comparison to the same week last year.

Similarly, London police recorded a 1,353% increase in antisemitic crimes compared with the same period a year earlier.

In addition, antisemitic symbols and rhetoric seem to be part of a growing number of protests that erupted around the globe following the escalation of the conflict between Israel and Hamas.

Most scholars agree that the term “antisemitism” describes animosity and discrimination against Jews. Broader definitions, such as the one adopted by the International Holocaust Remembrance Alliance, include the singling out of Israel and the demonization of its character, such as the claim that “the existence of a State of Israel is a racist endeavor.”

My team of researchers at UMass Lowell and Development Service Group, a Washington, D.C.-based think tank, compiled and analyzed a comprehensive dataset of antisemitic incidents in the U.S. between 1990 and 2021. We wanted to understand what factors led to antisemitism. We covered violent antisemitism as well as incidents of antisemitic intimidation and vandalism. We included any attacks against Jews which were motivated by the religious identity of the victims – even if it was motivated by anger about Israeli policies.

Our study, which will be published soon, found a startling new phenomenon: The ideology underlying antisemitism in the U.S. now encompasses both sides of the political spectrum. And it allowed us to develop three other insights regarding the intensifying linkage between the Israeli-Palestinian conflict and antisemitism in the U.S.

1. Antisemitism is not exclusive to the far right
Traditionally, antisemitism in the United States was promoted by far-right organizations and movements, such as the Ku Klux Klan, neo-Nazi groups and skinheads. Such groups focused on propagating traditional antisemitic narratives alleging Jews’ racial inferiority, their control of the financial sector and their role in global cabals aiming to undermine America and Western civilization.
