Por Renan Filho · 2026-09-23New York — Mahmood Mamdani, the Uganda-born scholar of political violence who teaches at Columbia University, has taken aim at Israeli Prime Minister Benjamin Netanyahu in unusually blunt terms.
With Netanyahu preparing to address the United Nations General Assembly this week, Mamdani called the Israeli leader the "architect of horrific genocide" and said world leaders should treat him as a legal pariah, not a statesman.
Mamdani is not a fringe figure. His work on the Rwandan genocide, colonial state formation and the global war on terror is assigned in universities across the world.
For four decades, he has studied how states weaponize identity and how empires govern through local proxies. That is why his language carries particular weight when he says a democratic state's prime minister is designing a genocide.
The accusation lands at a delicate moment. Netanyahu has used past UN appearances to compare Israel's enemies to the Nazis. Ahead of the new General Assembly session, several governments are pushing for stronger language on the Palestinian question, and an advisory opinion by the International Court of Justice has declared Israel's decades-long occupation unlawful.
Mamdani's public interventions on Gaza have grown sharper since October 7, 2023. The Hamas-led attack that day killed around 1,200 people in Israel, according to official counts, and produced a military response that Gaza's health ministry says has killed tens of thousands of Palestinians. Mamdani argues that the scale and pattern of Israel's campaign cannot be explained as self-defense.
Why it matters: The word "genocide" is not a rhetorical ornament. Under the 1948 UN Convention, genocide requires acts committed with the intent to destroy, in whole or in part, a national, ethnic, racial or religious group. Mamdani and Netanyahu are thus fighting over how international courts and publics should determine intent.
For his critics, Mamdani's own record complicates the charge. His 2009 book Saviors and Survivors challenged the Western movement to label the Darfur conflict a genocide, arguing that the humanitarian campaign was being used to justify US military intervention in Sudan's affairs. He later faced accusations of downplaying the suffering of Darfuri civilians.
The episode is relevant. Mamdani does not toss the word "genocide" around casually, but he has shown a willingness to bend it to fit a regime-changing political narrative.
Supporters caution against reducing his career to a single book. They say he has spent years exposing the selective application of international law, and that the case against Netanyahu rests on evidence collected by Israeli human rights groups, UN rapporteurs and international courts.
In January 2024, the ICJ found that Palestinian rights under the Genocide Convention face a plausible risk. In May of that year, the ICC prosecutor requested arrest warrants for Netanyahu and then-Defense Minister Yoav Gallant.
None of that, however, converts Mamdani's epithet into a judicial ruling. The ICJ's provisional measures were exactly that: provisional. The ICC prosecutor's request was a request, not an indictment.
The phrase "architect of horrific genocide" is a political verdict. It short-circuits the evidence-gathering process by which the law is supposed to establish intent before the world's strongest moral vocabulary is deployed.
FORTIS analysis: A free society must distinguish between legitimate criticism and institutional delegitimization. Mamdani's career is full of legitimate criticism of American power, Israeli policy and the hypocrisy of Western diplomacy. That is good.
But when the word "genocide" is transformed into a rhetorical weapon used to isolate one political leader, fact-finding is replaced by celebrity scholarship. The same rule applies to those who celebrate indiscriminate violence: if the right uses imprecise legal categories to justify war, and the left uses them to justify delegitimizing entire states, the result is a weakened international order where might decides meaning.
Counterpoint: Those who welcome Mamdani's intervention argue that focusing on the label obscures the more important question: what is happening in Gaza? They point to the destruction of hospitals, the deaths of thousands of children, and the displacement of nearly the entire population as proof that the legal machinery of the UN is moving too slowly. In their view, the word "genocide" is not an insult but a description.
They also note that Mamdani's previous work on Darfur was intended to complicate the "good versus evil" narrative of Western intervention, not to erase African suffering. The same instinct, they say, now drives his denunciation of Israel.
The timing is telling. Netanyahu travels to New York with the ICC and the ICJ breathing down his neck and with a fractious coalition at home. Mamdani, from an American campus, is trying to shape the narrative before the Israeli leader takes the podium.
The UN is a stage, and both men know that the audience is not the diplomats in the hall. It is the global public that will vote in elections, file lawfare cases and remember the images.
