Yom HaShoah 2026: Record Antisemitic Deaths as the World Watches

As Israel pauses for Holocaust Remembrance Day tonight, a Tel Aviv University annual report delivers a sober indictment: 2025 was the deadliest year for antisemitic violence since the 1994 Buenos Aires bombing, with 20 Jews killed in antisemitic attacks worldwide and incidents logged in 72 countries. The report's release on Yom HaShoah — the same day Trump orders a naval blockade of Iran — underscores the stakes of the current moment. The UK topped per-capita antisemitic assaults; Jewish communities in Canada, Ireland, and the Netherlands faced organized violence. Israel counts 111,000 survivors in 2026, a dwindling generation.

• 20 Jews killed in antisemitic attacks globally in 2025 — the highest death toll since the 1994 AMIA bombing in Buenos Aires that killed 85.
• 1,000+ antisemitic incidents documented in 72 countries, per the Israel Ministry of Diaspora Affairs, with a moderate overall increase from 2024 but a massive jump from pre-October 7 baselines.
• The UK topped per-capita antisemitic assaults in 2025 for the second consecutive year, per JNS/TAU data — ambulances set ablaze, Jews murdered on Yom Kippur.
• 111,000 Holocaust survivors remain alive in Israel in 2026, according to government estimates released ahead of Yom HaShoah — a reminder that living memory is disappearing.
• The TAU report notes that despite a Gaza ceasefire in early 2026, antisemitism rates remained elevated or rose in several countries — decoupled from the conflict's tempo.

For ICAN, this report is the annual benchmark: it quantifies the threat environment in which we operate and provides the factual foundation for every legislative and advocacy argument we make. The combination of today's Yom HaShoah commemoration and this data provides maximum advocacy leverage — legislators, editorial boards, and donors will be receiving these numbers today.

Trump announced Sunday that U.S. naval forces will blockade all maritime traffic at Iranian ports, effective 10 a.m. ET today (Monday), after 21 hours of talks in Islamabad collapsed without a deal. Iran rejected U.S. demands to halt uranium enrichment and stop funding proxies. NATO allies declined to join. Congress returns from recess with House Democrats planning a War Powers vote Thursday — and sensing potential GOP defections.

• CENTCOM confirmed blockade begins April 13 at 10 a.m. ET, blocking all maritime traffic entering and exiting Iranian ports — a significant military escalation.
• Iran rejected core U.S. demands: halting uranium enrichment and ceasing proxy funding, per senior U.S. officials — the talks were described as '21 hours with too little time.'
• NATO allies including the UK refused to join the blockade, creating a diplomatic isolation dynamic that Iran's messaging has already seized on.
• House Democrats plan a Thursday War Powers Resolution vote, and are sensing potential Republican defections as the economic costs of the Iran conflict mount.
• Netanyahu publicly backed the blockade, stating the ceasefire 'could end at any moment' — Israel is preparing for a possible Iranian surprise attack.

The blockade shifts the conflict from kinetic strikes into economic siege — a strategy with unpredictable escalation timelines. For ICAN, the War Powers vote Thursday is a direct test of congressional support for the U.S.-Israel war effort. Watch which Democrats vote with the GOP to block the WPR and which Republicans defect.

New York Mayor Zohran Mamdani marked his first 100 days in office Sunday with a rally and speech — and immediately faced a formal ADL failing grade. The league said Mamdani has 'neglected to proactively protect Jews and rescinded key antisemitism protections' while positioning himself as a friend of the community. NYPD data shows over half of all hate crimes in NYC since he took office have targeted Jews. Multiple commentators and a NY Daily News editorial described his tenure as all balancing act, no action.

• The ADL formally flunked Mamdani's first 100 days on antisemitism, saying he 'neglected to proactively protect Jews' and walked back key protections.
• Over half of NYC hate crimes since inauguration targeted Jews, per NYPD data — a rate that has drawn bipartisan concern.
• Mamdani's 100-day rally framed his tenure around rent freezes, child care, and transit — Israel and antisemitism were conspicuously absent from his public remarks.
• A RealClearPolitics analysis headlined 'Mamdani's Gotten Zero Results — Except Fanning Jew-Hate' synthesized the policy and community safety failures.
• Mamdani has previously condemned antisemitism in statements but critics say verbal condemnation is disconnected from policy action or community engagement.

Mamdani running the largest Jewish city in America while the ADL publicly flunks him is a major political story and an advocacy target. His 100-day accountability moment is an opening for Jewish community organizations, editorial boards, and allied legislators to demand specific policy commitments.

Jewish Insider's analysis of the Iron Dome debate reveals a broader pattern: the range of publicly acceptable positions on Israel among Democratic candidates has shifted significantly leftward over the past 18 months. Candidates who once wouldn't touch missile defense funding are now running ads on it — and the shift is being tracked in real time by pro-Israel and anti-Israel PACs alike as a proxy for general Israel positions.

• JI maps the 'Overton Window' on Israel among Democratic primaries: positions that were fringe in 2024 are now mainstream primary positions in competitive districts.
• The Iron Dome debate — which PRISM tracked last week — is now being used as a loyalty signal by both pro-Israel and anti-Israel PACs in candidate vetting.
• Progressive candidates who explicitly oppose offensive weapons to Israel but support Iron Dome are occupying a new middle lane that the movement has not resolved ideologically.
• DMFI's first 2026 ad targeting California Democrat Ammar Campa-Najjar (referenced in state.json) is the opening salvo of a new cycle of primary accountability.

This is the threat model ICAN operates inside: as the Overton Window shifts, the safe middle evaporates. Tracking who occupies the new 'acceptable opposition' lane and whether it becomes normalized is the core analytical challenge for the next 18 months of primary season.
