Mamdani Exploring Option of Arresting Netanyahu During U.N. Visit

New York City Mayor Zohran Mamdani is once again attempting to place City Hall at the center of an international dispute, this time by examining whether municipal authorities could arrest Israeli Prime Minister Benjamin Netanyahu during an expected visit to the United Nations General Assembly.

Mamdani confirmed that his administration is in an “active conversation” with the city’s Law Department over what authority, if any, New York officials might possess if Netanyahu travels to Manhattan in September. The mayor previously raised the same possibility while campaigning for office and has continued pursuing the matter since being sworn in on January 1.

The Democratic socialist justified the inquiry by invoking the International Criminal Court’s arrest warrant against the Israeli leader.

“He’s a war criminal who has been charged by the International Criminal Court,” Mamdani said.

“And what you will find is that is an opinion that is held by many, purely because of what his actions have wrought over these last many years,” he added.

The ICC issued its warrant in November 2024, alleging that Netanyahu bears responsibility for war crimes and crimes against humanity connected to Israel’s military campaign against Hamas in Gaza. Israel has rejected the allegations and challenged the court’s jurisdiction.

Mamdani’s rhetoric reflects the growing hostility toward Israel among progressive Democrats, but turning that political position into an arrest by the New York Police Department would present far more serious legal and constitutional obstacles.

The United States is not a party to the Rome Statute that created the ICC and does not accept the court’s authority over American or Israeli officials. President Donald Trump reinforced that position during his second term by imposing sanctions on the ICC and declaring that its actions against Netanyahu and other officials threatened American sovereignty and foreign policy.

Foreign relations are directed by the federal government, not municipal politicians. An attempt by a city mayor to detain a visiting allied leader based on an international warrant rejected by Washington would almost certainly provoke an immediate conflict with the Trump administration.

Mamdani acknowledged that his authority may not extend nearly as far as his campaign rhetoric suggested.

“Whatever the law allows me to do in New York City, that’s what we will do, but we won’t be writing our own laws to that end,” he said.

That qualification marks a retreat from the more sweeping promise Mamdani made before becoming mayor, when he suggested he would direct the NYPD to arrest Netanyahu if the Israeli leader entered the city. Legal experts previously described such an action as a practical impossibility that could place City Hall in direct confrontation with the federal government.

Netanyahu Dismisses Mamdani’s Threat

Netanyahu has treated the mayor’s repeated arrest threats as political theater rather than a serious legal danger.

During an interview with New York radio host Sid Rosenberg, the Israeli prime minister called the idea “silly” and indicated that it would not deter him from visiting the city.

Netanyahu then turned his attention to Mamdani’s broader record on Israel and Hamas.

“I think he should look at who he’s condemning and who he’s praising,” Netanyahu said.

“He’s condemning Israel, the one democracy that stands shoulder to shoulder with American values.”

The Israeli leader argued that Mamdani has directed his hostility toward a democratic American ally while minimizing the nature of the terrorist organization that initiated the war with its October 7, 2023, attack.

“Who does he champion? Hamas, that calls openly to massacre every Jew on earth, that conducted that horrible massacre, the worst massacre on Jews since the Holocaust,” Netanyahu said.

Netanyahu also warned that the ideological hostility directed against Israel frequently extends to the United States.

“The problem is that he either doesn’t understand, or doesn’t care, that those who hate the Jews and Israel ultimately also hate America.”

“In fact, I think secretly, he hates America,” Netanyahu said.

Mamdani denies supporting Hamas and has rejected accusations of antisemitism. He has said his condemnation is directed at Netanyahu’s government and Israel’s conduct in Gaza rather than Jewish people. Mamdani has also publicly condemned the October 7 Hamas massacre as a war crime.

City Hall Has No Business Conducting Its Own Foreign Policy

The controversy illustrates the danger of municipal leaders attempting to conduct an independent foreign policy based on partisan ideology.

New York’s mayor is responsible for policing, sanitation, housing, transportation and public safety in America’s largest city. He is not the secretary of state, the attorney general or the president of the United States.

The city also serves as the home of the United Nations, where foreign heads of government regularly travel to address the General Assembly. Federal law and international agreements provide protections for foreign representatives conducting official business at international organizations, further complicating any fantasy of a unilateral City Hall arrest.

Trump’s administration has already made its position unmistakable. The White House rejects ICC jurisdiction over Israel, considers Netanyahu a protected official of a close American ally and has authorized sanctions against those who assist certain ICC efforts targeting protected individuals.

Mamdani may continue searching for a legal loophole, but the mayor cannot simply transform his ideological opposition to Israel into a municipal foreign policy.

His fixation also raises a more basic question for New Yorkers: Why is their mayor devoting government time and legal resources to threatening the leader of a democratic ally instead of concentrating on the immediate responsibilities of City Hall?

The answer may be political. Confronting Netanyahu strengthens Mamdani’s standing with the socialist and anti-Israel movement that helped fuel his rise. Whether it serves the legal, diplomatic or practical interests of New York City is an entirely different matter.
