Has Netanyahu spoken? What happened with him and Mamdani?

Netanyahu is scheduled to arrive in New York this Thursday morning and address the General Assembly at 2 p.m., before returning to Israel the same day. His visit was originally planned to stretch several days and include a stop in Texas and a meeting with President Donald Trump, but it has been shortened to a single in-and-out: arrive Thursday, speak at 2 p.m., leave.

Netanyahu had reportedly considered skipping this year's gathering but ultimately decided to attend, viewing the speech as an opportunity to bolster his campaign ahead of Israeli elections.

The Mamdani standoff

Zohran Mamdani is the 112th Mayor of New York City, the city's first Muslim and first Asian American to hold that office. He has been mayor since January 1, 2026, elected as a Democrat and a member of the Democratic Socialists of America.

The tension between the two men goes back to a core legal question. The International Criminal Court, or ICC, the international body set up to prosecute individuals for war crimes and crimes against humanity, issued an arrest warrant for Netanyahu in 2024 over alleged war crimes in Gaza. Mamdani made honoring that warrant a campaign promise.

On Monday, Mamdani again called for the ICC warrant to be honored, telling CNN he believes Netanyahu to be "a war criminal and an architect of a horrific genocide of the Palestinian people." He acknowledged he does not have the authority to carry out the warrant himself, but said it should still be "honored" to protect accountability to international law.

Back in July, Mamdani had investigated the possibility of arresting Netanyahu based on the ICC warrant, concluded after a few days that he could not legally do so, but still warned that Netanyahu was "not welcome" in New York City.

Netanyahu fired back on video today. In a video shared on X, he wrote "Shame on you, Mr. Mamdani," accusing the mayor of "supporting the Hamas terrorist monsters who butchered our people" and "inciting riots against New York Jews." He added: "I'm coming to the U.N., I'm going to tell the truth about our heroic soldiers, and I'm going to tell the truth about you."

Mamdani responded that "what the prime minister said in that video is not true," and pointed out that Netanyahu "is the subject of an International Criminal Court warrant for alleged war crimes and crimes against humanity."

The broader backdrop

Netanyahu's Likud party has also pulled Mamdani into Israel's domestic political fight, with a campaign billboard in September placing the New York mayor alongside Iran's Supreme Leader and other figures it said wanted Netanyahu to lose the election.

Few details have emerged regarding the content of Netanyahu's actual speech, and considerable attention is focused on the atmosphere inside the hall. Last year, numerous delegates staged a coordinated walkout the moment he began speaking. Israeli Ambassador to the UN Danny Danon predicted "another show" might unfold this year, but stressed that Netanyahu will deliver his message regardless.

President Trump has separately said Netanyahu will not be arrested in the United States. So the mayor's legal leverage was always limited, but the political argument it has sparked is playing out on the biggest diplomatic stage in the world.
