National Post ↗How it started
The conflict began when New York Mayor Zohran Mamdani publicly accused Israeli Prime Minister Benjamin Netanyahu of being a war criminal. Mamdani claimed Netanyahu should face arrest if he visited New York, citing alleged war crimes against Palestinians. These remarks came as Netanyahu was preparing to travel to the United States for the United Nations General Assembly.
Mamdani's statements were widely reported and quickly drew a response from Netanyahu, who used social media to address the accusations. This set the stage for a heated exchange between the two political figures.
How it unfolded
On September 22, Mamdani again called for Netanyahu's arrest during his planned visit to New York, repeating his claims about Israeli actions in Gaza and labeling the prime minister as responsible for genocide, according to Mehr News.
Netanyahu responded that same day with a video message, promising to "expose the truth" about Mamdani during his upcoming speech at the UN. He also accused Mamdani of supporting Hamas, intensifying the personal nature of the dispute, as reported by The Hill.
Mamdani did not back down and reiterated that no one, including Netanyahu, should be above international law. He referenced the International Criminal Court's authority to issue arrest warrants for those accused of war crimes, as Anadolu Ajansı noted.
The feud quickly gained political traction in the United States. A US senator, Chris Van Hollen, defended Mamdani, stating that Netanyahu's accusations did not change the fact that he considered Netanyahu a war criminal, according to Middle East Eye.
Netanyahu maintained that his UN speech would defend Israel's military operations and address the controversy directly, according to Times of India and National Post.
Where it stands
As of now, the dispute between Netanyahu and Mamdani remains unresolved and highly public. Netanyahu is set to address the UN General Assembly in New York, where he has indicated he will respond to Mamdani's accusations from the global stage.
The exchange has drawn international attention and sparked debate in US political circles, with some lawmakers siding with Mamdani and others watching the developments closely. Both sides have doubled down on their positions, and the issue has become a focal point during Netanyahu's high-profile visit.
What to watch
Netanyahu's speech at the UN General Assembly is expected to address both Israel's military actions and the accusations raised by Mamdani. Observers will be watching for any further escalation between the two and for potential diplomatic or legal fallout from the public confrontation.
