Is Netanyahu’s beef with Mamdani helping him politically?

Experts say PM, facing tough reelection campaign, has painted himself as a bulwark against a New York City mayor who is an icon of global anti-Israel sentiment

JTA — Benjamin Netanyahu’s speech at the United Nations General Assembly this year came at a critical time for Israel. Talks were underway to resolve the conflicts in Gaza, Lebanon and Syria, and Israel was awaiting the outcome of the on-again, off-again US-Iran ceasefire negotiations. The country had also just been sanctioned by 12 countries, led by Britain, over its West Bank policies.

Yet it was Zohran Mamdani, the New York mayor who has virtually no say in international relations, who drew the Israeli prime minister’s fiercest, most lengthy criticism. Mamdani, Netanyahu charged, was an antisemite, a “buddy” of Hamas, the husband of a supporter of the October 7 massacre and the friend of a 9/11 enthusiast.

The UN address wasn’t the only time in the weeks leading up to Israel’s October 27 election that Netanyahu focused his sights on Mamdani in an unusual forum. In August, Netanyahu’s Likud party launched an election billboard campaign showing Mamdani alongside Turkish President Recep Tayyip Erdogan, Iran’s Supreme Leader Mojtaba Khamenei, and Hezbollah Secretary-General Naim Qassem, with the slogan, “They want Netanyahu to lose, don’t let them win.”

In the weeks leading up to his visit to UN headquarters in New York, the prime minister and Mamdani went at each other on social media, with Mamdani calling for Netanyahu’s arrest in New York (while acknowledging he had no power to order it), and the prime minister accusing the mayor of antisemitism and support of Hamas.

Netanyahu is making the New York mayor a central bogeyman this election season – is it working?

It’s true that Mamdani, who is Muslim, is unpopular across most of the Jewish political spectrum in Israel. During his election campaign and since taking office, Mamdani has constantly accused Israel of genocide and ethnic cleansing, charges most Jewish Israelis and politicians from both coalition and opposition parties reject.

But it is unlikely that the average Israeli would base his or her vote on a candidate’s attitude toward the mayor of New York. After all, Israelis have many other issues on their plate that are closer to home, such as the state of national security, accountability for the failures that allowed Hamas to carry out its deadly raids inside Israel on October 7ת and the exemption of ultra-Orthodox Israelis from IDF service.

Still, Netanyahu aide Caroline Glick, the prime minister’s international affairs adviser, said in an interview it was “obvious” and “self-explaining” that the prime minister would push back against a person who has been “spewing antisemitism.”

Glick repeated Netanyahu’s claim in his speech that New York Jews felt unsafe as a result of Mamdani’s rhetoric and policies. She said Mamdani “got what he ordered up” in the premier’s UN address. (Mamdani pushed back sharply on what he called Netanyahu’s “baseless lies” in the speech.)

Danny Danon, Israel’s ambassador to the United Nations, said Mamdani started it. Mamdani “began a smear campaign already in July,” Danon said, referring to the video in which Mamdani called on the federal government to arrest Netanyahu, and the beefs on social media since then. Mamdani “fuels the fire and incites, and our approach is not to keep quiet versus inciters,” Danon wrote to the Jewish Telegraphic Agency in response to a query.

There are plenty of other targets that Netanyahu can attack to bolster his reputation as a fighter. He took aim in his UN speech at the “moral cowards” who left the hall when he rose to speak, Syrian President Ahmed al-Sharaa, French President Emmanuel Macron, Turkish President Erdogan, Qatar, and the protestקrs outside the UN building.

So why did Mamdani consume so much oxygen?

Guy Levy, a spokesperson for Netanyahu’s Likud party, explained that Mamdani is not just a personal adversary but an emblem of a larger struggle. “Mamdani is a symbol of the rise in the West of the connection between the radical Left and Islamists and antisemites,” he told JTA.

That connects with a larger theme in Netanyahu’s campaign: arguing that a governing coalition without him would be dependent on a majority-Arab party and on the left-wing Democrats to get enough seats to form a majority. As such, he contends, they would be unable or unwilling to safeguard Israeli security interests.

The campaign’s most recent slogan is, “It’s either the Right or Palestine” (the two words rhyme in Hebrew), indicating that a rival government would agree to Palestinian statehood, which many Israelis view as a danger. Mamdani, according to Levy, is part of the same left-wing/Arab camp; attacking Mamdani is therefore an attack against Netanyahu’s political rivals.

Dahlia Scheindlin, a veteran Israeli-American pollster and senior political analyst for the left-wing Haaretz newspaper and a staunch Netanyahu critic, speculated that the decision to go after Mamdani may not have represented a premeditated strategy but rather a “scattershot” approach born out of the prime minister’s poor performance in polls.

“First of all, not much has helped Netanyahu electorally,” Scheindlin said in a phone interview with JTA. “His party is stuck in the polls. It hasn’t changed in a very long time.” She noted that the Likud is currently polling at around 20 to 22 seats or even lower and that the bloc of parties loyal to him for forming a coalition hovers at about 50 to 52 seats – far short of the 61 needed to be in the majority.

Netanyahu has been pushing two major themes in his election campaign, according to Scheindlin: a “positive” theme, stressing his government’s successes against Hamas, Hezbollah and Iran; and a “negative” theme against likely Arab participation in a rival government led by Yashar party head Gadi Eisenkot, who is polling best right now.

The attacks against Mamdani fit into the negative frame, Scheindlin argued.

“The one about Mamdani plays into the theme that the whole world is against us, the world is being taken over by Muslims,” Scheindlin said. “These are openly racialized and racist themes against an Arab party and the Israeli government, against Muslims and anywhere else in the world.”

She added that Netanyahu and his government have been claiming that “any criticism coming from Europe of Israel is all because Europe has been taken over by Muslims,” and the New York focus now only expands that message in arguing that radical Islam has taken over the world.

During this government’s tenure, Israel’s standing in both Europe and the US has plummeted, with many European countries imposing sanctions and arms sales blocks and expressing harsh criticism of Israel’s actions in the West Bank and Gaza. Now Netanyahu “is going to be the defender by attacking people like Mamdani rhetorically and politically,” she said.

Scheindlin said she did not believe that Mamdani’s presence in the Likud’s election campaign would sway any voters. “The Mamdani sign came and went. I would doubt if most Israelis even remember it right now,” she said. And while the attacks against Mamdani generally “played into his message,” the bottom line is that Netanyahu is “trying everything” at this point in the campaign.

Yaakov Katz, the former editor-in-chief of The Jerusalem Post, viewed the speech less as a desperate play and more as a natural part of Netanyahu’s election campaign. In an interview with CBS, Katz said that the speech’s idea was for Israelis to think that “The world is against us no matter what, but thank God we have a leader, in this case, Netanyahu, who can stand up to everyone and stick it to them.” Katz added that “this could bring him some votes, or at the very least consolidate the base.”

Calling Mamdani an antisemite and blaming him for Jews feeling unsafe in New York “plays out well,” Katz said to CBS, “because Israelis look at people like Mamdani and they don’t see much of a difference, whether it’s Mamdani or it’s President Erdogan of Turkey, or it’s some other tent encampment or protest on the streets of Sydney or Paris or London. It’s one and the same.”

With the UN speech behind him and more pressing issues to address, including new revelations about warnings Netanyahu received prior to Oct. 7 and the flydubai attack last week, the Mamdani-Netanyahu fight has receded into the rear-view mirror. But if Netanyahu is reelected or if he stays on as caretaker prime minister, the issue will likely resurface.

Mamdani focuses on Netanyahu now, but he has made clear over his career that his problem is generally with Israel, whichever government is leading it. Even if a new administration takes over in Jerusalem, it may find itself at odds with the mayor of New York – and with the growing movement of young democratic socialists that he represents.
