2025: The year in which antisemitism became an algorithm of hate

From campuses to newsrooms, the hatred of Jews has become a tool—profitable, fashionable and deadly.

Fiamma Nirenstein is an Italian-Israeli journalist, author and senior research fellow at the Jerusalem Center for Security and Foreign Affairs (JCFA). An adviser on antisemitism to Israel’s Ministry of Foreign Affairs, she served in the Italian Parliament (2008-2013) as vice president of the Foreign Affairs Committee. A founding member of the Friends of Israel Initiative, she has written 15 books, including October 7, Antisemitism and the War on the West, and is a leading voice on Israel, the Middle East, Europe and the fight against antisemitism.

Forget lamentation. After a year of disgrace, it is not Jews who should hang their heads, but the antisemites themselves.

More than 6,300 antisemitic incidents recorded in 11 months in 2025—spiking dramatically across Europe—do not describe Jewish fragility. They expose the moral collapse of societies that have normalized hatred. Antisemitism has become an algorithm: a ready-made instrument to mobilize crowds, sell headlines, build careers and legitimize violence.

We have watched it parade as humanitarianism. A “flotilla” theatrically staged by Greta Thunberg’s circle claimed to bring food while money flowed to Hamas. We have seen Amsterdam—home of Anne Frank—declare Maccabi fans unwelcome. We have watched classrooms fed historical illiteracy, recited by Francesca Albanese, to tens of thousands of students. We have followed this logic to Bondi Beach, where Jewish families celebrating Chanukah were gunned down.

Italy, tragically, is no exception. Bookstores overflow with fashionable falsehoods by Ilan Pappe and Anna Foa. Public buildings, unions and municipalities drape themselves in Palestinian flags. Television news criminalizes Israel by reflex, untethered from facts, because outrage sells. Even the death of a newborn in Gaza becomes an accusation—never a tragedy—because Israel must always be guilty.

As the late historian Robert Wistrich warned, the key is not asking endlessly why antisemitism exists, but recognizing how it mutates. This year revealed its latest mutation: total normalization. “Genocide” and “war crimes” are now casual labels for Israel, deployed without evidence, stripped of meaning.

The market for hatred is vast. Islamists brand Jews as white supremacists. Parts of the left cast them as colonial fascists. The populist right monetizes resentment through podcasts and platforms.

Qatar amplifies it through Al Jazeera; Iran weaponizes it for Shi’ite supremacy; Turkey’s President Recep Tayyip Erdoğan mirrors it from the Sunni world. China and Russia know that anti-Israel fervor weakens the West—and even undermines U.S. President Donald Trump. A hollow pacifism finds its enemy in Israel alone, absolving Hamas and Hezbollah of responsibility.

The killers at Bondi and the Hamas financiers uncovered in Italy are not aberrations. They exist within our media ecosystems, our festivals, our institutions. They are applauded, excused and rewarded.

And yet—this is the essential difference from the past—there will be no new Shoah. The encirclement has been broken. Jews are strong. They are different. And, most importantly, they have Israel behind them.

That is the paradox of the past dark year: Antisemitism has become louder, cruder, more profitable—and at the same time less capable of finishing what it begins. The hope for a better and more peaceful year ahead lies precisely there.

The Israeli premier invoked Passover’s Ten Plagues, citing “ten blows” against Iran and “ten achievements,” including Israel’s unprecedented coordination with the United States.
One girl was severely injured in the four volleys that targeted the country’s most populated area hours before a major holiday.
The New York City mayor, who is a harsh and frequent critic of Israel, also wove his plans on affordability and to fight U.S. immigration policy into his telling of the holiday story.
The defense minister said residents of Southern Lebanon would be barred from returning “until the safety and security of northern Israeli residents is ensured.”
Limor Son Har-Melech, who introduced the bill and whose husband was murdered in a 2003 terror attack, stated that the “historic law” means “whoever chooses to murder Jews because they are Jews forfeits their right to live.”
The Jewish Electorate Institute poll largely conforms with surveys of the general U.S. public, which have found that most Americans oppose the war against Iran, with sharp partisan divisions between Republicans and Democrats.
