 AI Overview

Yes, the "dancing Israelis" narrative is an antisemitic conspiracy theory and a baseless myth that claims Israel or Jewish people had foreknowledge of or involvement in the September 11 terrorist attacks. [1, 2, 3]

Origin of the Myth

The Arrests: On 9/11, police detained five young Israeli men in New Jersey after a witness reported seeing them acting jovial and taking photos while watching the World Trade Center burn. [1, 2, 3]
The Investigation: The FBI detained and thoroughly investigated the men, conducting multiple background checks and polygraph tests. [1]
The Conclusion: The FBI and the 9/11 Commission found zero connection between the men and the terrorist attacks. They were held solely for visa and immigration violations and subsequently deported back to Israel. [1, 2]

How it Became a Conspiracy Theory

Distorted Claims: Antisemites and conspiracy theorists twisted the mundane details of the temporary detentions into a fabricated narrative that Israeli intelligence (Mossad) orchestrated or celebrated the attacks. [1, 2, 3]
Propagation: The myth was further fueled by false claims spread in the weeks and years following 9/11—including statements by the father of a real hijacker—and continues to be used by extremist groups as propaganda to promote hatred against Jewish people. [1, 2, 3, 4]
