JERUSALEM — Outgoing New York City Mayor Eric Adams embarked on a multi-day swing through Israel, billed as both a show of solidarity amid rising antisemitism and a farewell visit. But it was also something else: likely the last international trip a New York City mayor will take for years, a point Adams wanted to underscore.

Mayor-elect Zohran Mamdani, a strident critic of Israel, has pledged not to visit the country, breaking with a tradition upheld by every mayor since 1951 to demonstrate solidarity with Jewish constituents at home. He has also vowed to end the city’s decades-long practice of investing millions in Israeli government debt securities and has said he would order the arrest of Prime Minister Benjamin Netanyahu if he lands in New York.

“I think he has to have the level of political maturity to understand that government is not protesting,” Adams said in a fireside chat at an event hosted in his honor by the Combat Antisemitism Movement (CAM) in Tel Aviv on Sunday evening. “And all those who are in his midst, like the Democratic Socialists of America, he needs to explain to them that he’s now the mayor. He’s no longer someone that is just protesting in the city of New York. He has to protect the city of New York.”

In the 30-minute conversation, moderated by Sacha Roytman, chief executive of CAM, Adams repeatedly alluded to the impact of Mamdani’s political rise and victory in the mayoral election earlier this month. The outgoing mayor said he told his team a year ago that Mamdani was on track to win the Democratic primary and that he expected to face him in a general election showdown, believing he could beat him.

Adams made combating antisemitism central to his reelection effort. Elected as a Democrat in 2021, he later lost key support after striking a deal with the Trump administration to drop his corruption case, prompting him to run for a second term on an independent line dubbed “End Antisemitism.” He became popular in Israel after delivering a forceful speech at a New York City rally in the days following the Oct. 7, 2023 Hamas attack on Israel, in which he declared, “We are not alright.” He also resisted progressive pressure to distance himself from Israel and faced backlash for his crackdown on pro-Palestinian protests at colleges and across the city. Adams recently signed an executive order adopting the International Holocaust Remembrance Alliance definition of antisemitism, which labels most forms of anti-Zionism as antisemitic.

Mamdani, who attended some of the pro-Palestinian protests, faced the most scrutiny for refusing to outright condemn the slogan “globalize the intifada” and for saying he doesn’t recognize Israel as a Jewish state.

At the Sunday event, Adams took several shots at Mamdani, calling his election “abnormal” and questioning whether outside actors had influenced the race by shaping social-media algorithms. He suggested that the seeds of Mamdani’s campaign, powered by youthful energy and a promise of unconventional change, were planted during the protests against Israel.

“He had a ready-made army,” Adams said. “He had the Free Palestine movement that was heavily in place. He had the war that was going on, and then he had a group of angry youth on our college campuses. So when he emerged and said he was going to run on one issue, the Free Palestine movement, he already had the army that responded to him.” (Mamdani also ran on issues of affordability, universal childcare, and free buses.)

Adams said the Jewish community in New York “must prepare itself” to respond to any antisemitic attacks that might come. “I think this is a period where they need to be very conscious that there’s a level of global hostility towards the Jewish community,” he said, adding, “If I was a Jewish New Yorker with children, I would be concerned right now.”

Speaking with the Forward on Monday, Adams said he is being truthful about the situation. “I’m not going to lie to New Yorkers, I know what I’m seeing,” he said. “Other people will sugarcoat this moment, and I’m not going to do that. I’m not going to lie. I’m not going to pretend as though everything is fine.” To his critics, Adams said, “Those who want to interpret my candid view of what’s playing out now in our city and across the globe, they can do so. That is not up to me to try to convince them of what I am seeing and what I am hearing and what is playing out.”

The outgoing mayor is expected to meet with Israeli Prime Minister Benjamin Netanyahu at his office on Tuesday. Netanyahu said in an interview last week, commenting on Mamdani’s win, “If that’s the future of New York, I think New York has a very dim future.” Adams said he’ll assure Netanyahu and other leaders he is meeting with the “49% of New Yorkers did not buy into the rhetoric of the hatred towards Israel.” Madani won with 50.4% of the more than two million votes cast.

Other highlights of Adams’ Israel trip

Earlier in the day, Adams held an emotional 30-minute meeting with three former Israeli hostages — Yarden Bibas, whose wife Shiri and young sons Kfir and Ariel were murdered in captivity; Sagi Dekel-Chen, an American-Israeli released in a ceasefire deal in January; and Bar Kuperstein, who was among the last 20 living hostages freed last month.

Held at the World Jewish Sports Museum at Kfar Maccabiah, Dekel-Chen described his time in captivity and the slow and painful process of healing. Bibas described his life in grief, adding that his only purpose is “to stay alive and remember my wife and kids.”

Adams, visibly shaken, told the former hostages that he admired their resilience and that New Yorkers needed to hear these stories firsthand. He offered to host them for the ball drop in Times Square on New Year’s Eve.

At the museum, Roy Hessing, deputy CEO of the Maccabiah movement, invited Adams to serve as an honorary guest at the next Maccabiah Games, now scheduled to resume in June, after delays due to the war. The event is expected to draw 30,000 participants, including 15,000 from abroad.

Adams also paid a visit to the Western Wall on Sunday night, where he placed a note in the wall and prayed. In the guestbook, Adams wrote that “God is real and life has shown us this.”

Shortly after landing on Saturday, Adams walked through the Nachalat Binyamin neighborhood with Tel Aviv’s deputy mayor, Asaf Zamir, who was Israel’s consul general in New York from 2021 to 2023. Zamir was outspoken against Mamdani throughout the mayoral campaign. Adams has long referred to New York as the “Tel Aviv of America.”

In tours closed to the press, Adams visited the IMI Academy, where Israeli instructors provide tactical and emergency-response training, and the Aerial Systems facility, where he was shown the latest drone and surveillance technologies. He also addressed the annual mayors’ conference hosted by the American Jewish Congress at Jerusalem’s King David Hotel.

At many of his stops, Adams said about his farewell: “I’m not just the mayor that’s leaving office, I’m your brother.”
