Between October 7 and 23, 2023, ADL identified 312 incidents. Of these, 190 were directly associated with the conflict in Israel and Gaza. In comparison, only 64 incidents were reported during the same timeframe in 2022, of which four were related to Israel.
Following the October 7 attack, nearly 400 anti-Israel rallies have been tracked by the ADL. Of these rallies, 109 demonstrated explicit or strong implicit support for Hamas or displayed violent intentions towards Jews in Israel. These 109 events are included in the antisemitic incident count.
ADL CEO Jonathan Greenblatt expressed his concerns: “When conflict erupts in Israel, antisemitic incidents soon follow in the US and globally. From white supremacists in California to radical anti-Zionists, we are witnessing a troubling surge in antisemitic behavior domestically while conflict intensifies abroad.”
Moreover, the ADL observed a near 1,000-percent surge in violent messages mentioning Jews and Israel on Telegram following the Hamas attack.
Greenblatt urged leaders at all levels to stand firm against antisemitism and terrorism: “Words matter. We call on those in power to use their platforms to condemn hate and terrorism, no matter where it manifests.”
A top lawyer in the Illinois state government told a Jewish person, “Hitler should have eradicated all of you.” An Israeli student was assaulted at Columbia University. And Jewish schools and synagogues in at least three different states have been subjected to violent threats.
Those are a few of the incidents that have occurred during the spike in antisemitic activity in the United States since Hamas invaded Israel.
That reported increase in antisemitism has put Jewish communities – and the US government – on guard as the war in Gaza and Israel dominates the headlines, even as Jewish security agencies have not warned of any credible threats of violence. Hillel International is providing new funding for armed guards on college campuses, and other Jewish institutions are also bolstering security. Last week, Attorney General Merrick Garland announced that the Justice Department was monitoring an increase in reported threats to Jewish, Muslim and Arab communities.
The ADL has tracked 193 incidents it classifies as antisemitic in the period following Hamas’s October 7 attack on Israel, an increase of more than 20% from the same time period last year, although reports of antisemitism are still coming in. Such incidents cover a wide range of activities and do not include participation in pro-Palestinian rallies. But Segal said any incident that “ascribes blame to the entire Jewish community for what is happening in Israel” would be counted.
The period after the October 7 invasion has also seen attacks and threats targeting Muslims in the United States, including the murder of a 6-year-old Palestinian-American boy in the Chicago area.
Amid all of this, nonprofits focused on Jewish security have, so far, not sounded the alarm. One such organization in New York, the Community Security Initiative, has advised Jewish institutions to “keep calm and carry on,” according to The New York Times.
Jewish security agencies also said two weeks ago they were not aware of any credible threats ahead connected to a Hamas-inspired “day of violence” against Jews worldwide on October 13.
'Part of our job is to do a little anxiety alleviation'
“People are calling the NYPD bomb squad because they got a package from Gaza that turns out it’s olive oil,” said Mitch Silber, director of the Community Security Initiative and a former intelligence official for the New York Police Department. He added that Hamas has no known formal capacity in the United States.
“It feels like pure panic mode the community is in, and part of our job is to do a little anxiety alleviation,” Silber said.
A spokesperson for the Secure Community Network, a nationwide security organization for Jewish institutions that operates a “command center” in Chicago, told JTA it was seeing “a significant increase in the threat environment for the Jewish community across North America” since October 7. However, its CEO Michael Masters added in a statement, the group was “not tracking any active, credible threats at this time.”
In the moments after the murder of a young Detroit synagogue president was reported, rumors swirled that the crime was linked to the Israel-Hamas war. But police say they have not seen any sign of antisemitism so far in their investigation.
Yet, there has indeed been a string of violent incidents and threats against Jews in cities across the US. In New York City, police say a man attacked a Jewish woman, and told her that he was punching her because she was Jewish.
On October 17 in Charlotte, North Carolina, the FBI announced it had arrested a man who had sent a threatening email to an area synagogue in which he vowed “public execution”; the threat came weeks after a rash of other emailed and phoned threats to synagogues across the country.
That same day, police in Miami Beach, Florida, arrested a homeless man who approached a local Jewish day school security guard, said, “I’m with Hamas,” and falsely claimed he was carrying explosives.
Other threats against Jews this month have come from working professionals. A professor at the University of California, Davis, posted online that “all these zionist journalists who spread propaganda and misinformation” could be targeted, and concluded the post with machete, ax and bloodrop emojis.
The university’s president announced Thursday that the school had placed the professor under investigation, and her name is no longer listed on the faculty page.
Illinois gov't counsel to Jewish lawyer: 'Hitler should have eradicated all of you'
And the Illinois comptroller’s office fired one of its legal counsels Thursday after the attorney was found to have left threatening comments on the anonymous Instagram page of a lawyer who identified as Jewish, including “Hitler should have eradicated all of you” and “all you Zionists will pay,” according to reports.
The attorney, Sarah Chowdhury, also served as president of the South Asian Bar Association; the legal group announced it had terminated her as well and apologized “for any harm” caused by her remarks.
Beyond threats of violence, American Jews have contended with antisemitic graffiti and vandalism over the past two weeks. Some of these incidents have occurred on university campuses. At Cal Poly Humboldt, in northern California, two days after the attacks, graffiti reading “Free Palestine F**k Israel” was found on a sukkah set up by the university’s Chabad-Lubavitch center. Graffiti reading “The Jews R Nazis” was also found next to a Jewish fraternity at the University of Pennsylvania on October 20, according to the campus newspaper.
A spokesperson for Hillel International, the umbrella organization for Jewish life on campus, told JTA last week it was providing unrestricted “emergency grants” to all its chapters, including to address security concerns and expanding staff “in this moment of crisis.”
Other Jewish institutions have been targeted as well. The day after the Humboldt incident, a synagogue in Fresno, California, had its windows smashed by a perpetrator who also left a note reading, “All Jewish businesses will be targeted.” A suspect has been taken into custody and charged with a hate crime, reported J. the Jewish News of Northern California.
