Zohran Mamdani's incoming administration as New York City's mayor is generating significant concern among Jewish communities, with leading rabbis warning of his anti-Zionist stance and rhetoric. Jewish leaders fear that Mamdani's policies and appointments, some with ties to anti-Zionist groups, could foster hostility and make the city less safe for Jews. His proposals include disbanding the police unit that responds to protests, dropping the official definition of antisemitism that covers some Israel criticism, and potentially ending the Office to Combat Antisemitism.

Mamdani has pledged to increase funding for hate violence prevention and to implement a school curriculum highlighting Jewish history, but his plans for these initiatives remain unclear. He opposes cutting public funds to yeshivas that do not meet state standards and has found some support among Hasidic communities. Mamdani will not attend the city's annual pro-Israel parade but says he will ensure its security. He also supports the Boycott, Divestment and Sanctions campaign against Israel and has proposed divesting city pension funds from Israel bonds, though city officials may block these efforts.

Additionally, Mamdani has stated he would arrest Israeli Prime Minister Benjamin Netanyahu if he visits New York, despite lacking the legal authority to do so. The incoming administration's approach to Jewish issues is expected to be shaped by counterweights in city government, including Jewish officials in key positions.
