The launch of Operation Epic Fury did not just trigger a spike in online antisemitism. It marked an escalation. The Blue Square Alliance Command Center’s new report on online antisemitism during Operation Epic Fury documents the surge in hate content that followed the U.S. and Israeli military operation against Iran starting on February 28, 2026. In the first week alone, antisemitic conversation surged 200 percent, contributing to more than 159 million posts that generated over 1 billion impressions through the ceasefire announced on April 7.
But the scale of the spike is only part of the story. Underlying all our findings is what the Command Center refers to as the Ratchet Effect: the pre-conflict weekly baseline of 12.6 million posts was nearly double what it had been before October 7, 2023, meaning each conflict cycle spikes higher and recedes to a permanently elevated floor. Antisemitism online is no longer episodic. It is compounding, creating a new and sustained baseline of hate.
That escalation is visible not just in volume, but in severity. Dehumanizing language surged in the opening days of the conflict and remained elevated throughout, with a 668 percent increase of posts comparing Jews, Israelis, and Zionists to animals and pests since the start of the war. At the same time, the report identifies a growing trend in which “Jew” is used as a slur against non-Jews, deployed to discredit individuals without engaging their views.
These narratives are not isolated. “False flag” narratives averaged 35,000 posts per day at 15 times the pre-conflict baseline, while conspiracy theories framing the war as a Jewish plot accumulated 254 million impressions. These narratives were not spreading organically. The report documents a coordinated AI disinformation campaign in the first nine days of the conflict, with nearly one in five amplifying accounts assessed as inauthentic. A single AI-generated deepfake narrative depicting the death of Prime Minister Netanyahu accumulated 430 million impressions before it could be effectively countered
The narratives themselves are not new. What has changed is the infrastructure through which they move. Longstanding tropes about Jewish power, control, and manipulation are now amplified at unprecedented speed and scale, shaping how millions of people understand events in real time. Read the full report for a deeper analysis of how these narratives take hold, who amplifies them, and how they scale.
