Gulf Widens Between Mamdani and Pro-Israel Jewish Leaders

The relationship between New York City Mayor Zohran Mamdani and pro-Israel Jewish leaders has reached a critical breaking point, marked by a series of escalating confrontations over Middle East policy that are reshaping political alliances in the nation’s largest city. The rift, which began during Mamdani’s 2025 mayoral campaign, has deepened significantly in his first months in office, with key flashpoints including his official Nakba Day video, the revocation of executive orders protecting Jewish institutions, and a boycott of his Jewish Heritage Month event at Gracie Mansion.

Background

Mamdani, the first Asian American and first Muslim mayor of New York City, took office in January 2026 after a stunning Democratic primary upset over former Governor Andrew Cuomo. A member of the Democratic Socialists of America, Mamdani has long been a vocal critic of Israeli policy, having co-founded a Students for Justice in Palestine chapter at Bowdoin College and expressed support for the Boycott, Divestment and Sanctions (BDS) movement during his campaign.

New York City is home to the largest Jewish community outside of Israel, with Jewish voters making up approximately 15% of the electorate. Previous mayors — Michael Bloomberg, Bill de Blasio, and Eric Adams — maintained strong relationships with Jewish leaders. Mamdani’s election represented a sharp break from that tradition.

The Breaking Points

Within hours of taking office on January 2, Mamdani revoked two executive orders signed by former Mayor Eric Adams — one adopting the International Holocaust Remembrance Alliance (IHRA) definition of antisemitism and another related to Israel bonds. Mamdani insisted the move was not targeted at the Jewish community, saying he wanted a “clean slate,” but a coalition of mainstream Jewish organizations issued a joint statement expressing deep concern, as the Forward reported.

The tensions escalated dramatically on May 15, when Mamdani posted an official Nakba Day video on city channels on a Friday afternoon, just before Shabbat began. The video, produced by City Hall staffers, featured Palestinian-American author Inea Bushnaq describing her family’s displacement during the 1948 Arab-Israeli war. It marked the first time a New York City mayor had officially commemorated Nakba Day.

Jewish leaders condemned the video as one-sided and divisive. The UJA-Federation of New York responded directly, stating: “Mayor Mamdani: the refugees you post about exist because 22 Arab states launched a war to destroy Israel on May 15, 1948 — rejecting the UN plan that also called for a Palestinian state.” Daniel Rosenthal, UJA’s vice president of government affairs, noted the irony of the timing, pointing out that on the same day, federal authorities indicted an Iraqi national with suspected Hezbollah ties who allegedly planned to bomb a New York City synagogue, as the New York Jewish Week reported.

The Boycott

On May 18, three high-profile Jewish leaders — including Mark Treyger, CEO of the Jewish Community Relations Council of New York and organizer of the Israel Day Parade — announced they would boycott Mamdani’s Shavuot and Jewish Heritage Month celebration at Gracie Mansion. “We will not be attending the Jewish American Heritage Month celebration at Gracie Mansion being hosted by a mayor who denies a core pillar of our heritage — the State of Israel as the homeland of the Jewish people,” the UJA-Federation said in a statement, as the New York Post reported.

Rabbi Joseph Potasnik of the New York Board of Rabbis also declined, saying: “Jewish heritage should include recognition of the state of Israel. Jewish history didn’t end in 1946.” Rabbi Avi Weiss went further, calling for all New York Jewish organizations to “boycott him, refuse to meet with him, and decline to invite him to communal functions.”

However, the Jewish community is not monolithic. Rabbi David Niederman of the United Jewish Organizations of Williamsburg attended the event, which drew approximately 150 people. Jewish Voice for Peace, a left-wing Jewish group, praised the Nakba Day video.

A Deepening Divide

A poll conducted by the Honan Strategy Group in December 2025 revealed a stark “temperature gap” between Jewish and non-Jewish voters. Among Jewish respondents, 53% said concerns about feeling threatened by Mamdani’s statements were legitimate, while 55% of non-Jewish voters dismissed these concerns as political overreaction. Additionally, 51% of Jewish voters viewed Mamdani’s rise as normalizing antisemitism, whereas 61% of non-Jewish voters saw it as evidence of healthy debate, according to the Forward.

Pollster Bradley Honan described the issue as “a defining political fault line in New York City,” noting that “Jewish voters are significantly more likely to say it’s making public antisemitism more acceptable and driving division.”

Analysis and Implications

The conflict represents more than a policy dispute — it is a clash over identity and belonging. Mamdani frames his positions as legitimate criticism of the Israeli government, arguing that “we must distinguish between antisemitism and criticism of the Israeli government.” Jewish leaders, however, see his actions as fundamentally delegitimizing the Jewish state and normalizing antisemitic rhetoric.

Mamdani has increased funding for hate crime prevention by 800% to $26 million and kept the Mayor’s Office to Combat Antisemitism open. Yet Jewish leaders argue that his rhetoric creates the environment that necessitates such spending.

The rift carries national significance. As the first Muslim mayor of New York City and a prominent progressive voice, Mamdani’s relationship with Jewish leaders reflects the broader Democratic Party tension between pro-Israel and pro-Palestinian factions. With the Israel Day Parade scheduled for May 31 — which Mamdani has said he will skip — and questions about whether he can repair relationships with mainstream Jewish organizations, the coming months will test whether this breach can be healed or has become permanent.

What’s Next

All eyes are on the Israel Day Parade on May 31, where security will be a major concern. Mamdani has confirmed he will not attend but has directed the NYPD to protect the march. The longer-term question is whether Mamdani can rebuild trust with mainstream Jewish organizations — or whether the divide will deepen further, potentially shaping his ability to govern and his prospects for reelection in 2029.

As the Jerusalem Post noted, Mamdani has previously sought input from Jewish leaders on sensitive statements, suggesting some channels of communication remain open. But the events of May 2026 have made clear that the gulf between the mayor and pro-Israel Jewish leaders is wider than ever.
