Mamdani Calls Netanyahu ‘War Criminal’ But Says He Can’t Arrest Him

Mayor’s Strong Words, Legal Limits

New York City Mayor Mamdani has ignited a political firestorm by calling Israeli Prime Minister Benjamin Netanyahu a “war criminal” — but immediately undercut his own rhetoric by admitting he cannot actually arrest him.

Speaking at a City Hall press conference on Wednesday, Mamdani did not hold back. “Netanyahu is a war criminal, plain and simple. He does not belong in this city,” he said. But when pressed by reporters on whether he would authorise police to detain the visiting leader, the mayor backtracked.

“I do not have the legal authority to arrest a sitting foreign head of state,” Mamdani said. “That is a matter for the federal government and international bodies.”

U-Turn or Clarification?

The remarks mark a sharp reversal from the mayor’s earlier tone. Just days ago, Mamdani hinted he might order Netanyahu’s arrest if he set foot in New York, citing the International Criminal Court’s (ICC) warrant against the Israeli leader. That pledge drew cheers from pro-Palestinian activists and outrage from Jewish groups and Israeli officials.

Now, with the prime minister expected to address the United Nations General Assembly next week, the mayor appears to be walking a tightrope. His office released a brief statement later, saying Mamdani “stands by his moral condemnation” but will “respect legal constraints.”

The mixed messaging has left many confused. Is this a climbdown, or simply a lecture in constitutional law?

Political Crossfire

Mamdani is catching flak from both sides. Pro-Israel groups have slammed him for the “war criminal” label, calling it inflammatory and diplomatically reckless. The Anti-Defamation League demanded an apology, saying the mayor was “poisoning the well” ahead of Netanyahu’s visit.

On the other flank, pro-Palestinian advocates accuse Mamdani of caving to pressure. “You can’t call someone a war criminal and then say your hands are tied,” said a spokesperson for Jewish Voice for Peace. “Either you act, or you don’t. This is a cop-out.”

Even within his own party, some see the episode as a self-inflicted wound. A senior Democratic strategist, speaking on condition of anonymity, told TIVRA News: “He picked a fight he couldn’t finish. That’s amateur hour.”

What the Law Actually Says

Under the Vienna Convention on Diplomatic Relations, sitting heads of state and government enjoy immunity from arrest while on official visits to foreign countries. The ICC warrant against Netanyahu, issued in May 2024 on charges related to the Gaza conflict, does not override this principle in domestic law.

Legal experts say Mamdani’s initial promise was always unenforceable. “A mayor cannot unilaterally enforce an ICC warrant,” said Dr. Aruna Mehta, professor of international law at JNU. “Even the U.S. federal government has not recognised the court’s jurisdiction in this case.”

The episode has laid bare the gap between political posturing and legal reality — a gap Mamdani is now forced to navigate.

What Comes Next

Netanyahu’s New York visit is still on schedule. Security preparations are underway, and the NYPD has said it will provide full protection to the prime minister regardless of the mayor’s personal views. Mamdani, meanwhile, has cancelled a planned counter-protest, citing unspecified “scheduling conflicts.”

All eyes will be on City Hall to see if the mayor doubles down, backtracks further, or simply stays silent. One thing is certain: this story is far from over.
