‘He’s a war criminal’: Mamdani exploring whether he can arrest Netanyahu if he visits New York

What Happened

New York City Mayor Zohran Mamdani stated he is reviewing whether his administration could order the NYPD to arrest Israeli Prime Minister Benjamin Netanyahu if he visits New York for the UN General Assembly in September, citing an International Criminal Court (ICC) arrest warrant issued in November 2024 for alleged war crimes in Gaza. Mamdani confirmed an ‘active conversation’ with the city’s law department to determine his legal authority. Netanyahu dismissed the threat, accused Mamdani of supporting Hamas, and signaled he plans to attend. The US does not recognize the ICC; President Donald Trump imposed sanctions on the court in February 2025, and UN Ambassador Mike Waltz called the arrest talk ‘pure political theater.’ Israeli UN Ambassador Danny Danon accused Mamdani of failing to confront antisemitism, while Mamdani noted increased funding for hate crime prevention.

Why It Matters

The standoff tests the practical reach of the ICC warrant in a non-member state and exposes a rift between municipal action and federal policy. It coincides with shifting US Democratic Party support for Israel: close to half of House Democrats voted to strip $3.3bn in military aid. A local arrest attempt could trigger a constitutional clash with Washington and strain US-Israel ties, while also signaling growing domestic pressure to hold Israeli leaders accountable under international law.

Watch For

Key moments include Netanyahu’s potential travel to New York for UNGA in September, the outcome of Mamdani’s legal review, and any federal intervention or further US sanctions on the ICC. Also monitor diplomatic fallout, reactions from ICC member states, and developments in Israel’s October election that could alter Netanyahu’s posture.
