Israeli Foreknowledge / Mossad Involvement Theory

The theory that Israeli intelligence had advance knowledge of, or involvement in, the September 11, 2001 attacks and failed to adequately warn the United States.

TypeIntelligence Operation / Foreknowledge Theory
First Articulated ByEarly reporting by Carl Cameron (Fox News, December 2001), investigative journalist Christopher Bollyn, and various researchers
Active Period2001 -- present
Key ClaimIsraeli intelligence maintained a surveillance operation tracking the 9/11 hijackers inside the United States, had advance knowledge the attacks were coming, and either failed to share critical intelligence or actively facilitated the operation
Evidence RatingMODERATE EVIDENCE

Overview​

Multiple documented incidents point to Israeli intelligence activity in the United States in the months preceding September 11, 2001 that intersected with the movements and activities of the hijackers. These include: the arrest and detention of five Israelis who were observed filming and celebrating the attacks on the World Trade Center; a DEA report documenting a network of approximately 140 Israelis operating inside the US posing as art students; warnings sent via an Israeli-owned instant messaging service hours before the attacks; and the role of an Israeli-founded security company at airports from which hijacked flights departed.

The theory ranges from the more conservative claim -- that Israel had foreknowledge it did not adequately share -- to the more aggressive claim that Israeli intelligence actively facilitated elements of the operation. Multiple mainstream news outlets reported on these events at the time, though coverage largely ceased after initial reporting.

The Israeli government has consistently denied any foreknowledge of or involvement in the September 11 attacks.

Evidence & Documentation​

The "Dancing Israelis" / Urban Moving Systems​

On the morning of September 11, 2001, a woman in New Jersey observed three men on the roof of a white van in a parking lot in Liberty State Park, apparently photographing and celebrating as the World Trade Center towers burned across the Hudson River. She reported them to police, and later that afternoon, five Israeli nationals were stopped in a white van belonging to Urban Moving Systems. Police found $4,700 in cash, foreign passports, and a box cutter. The men were detained for over two months, subjected to interrogation and polygraph tests.

The five men -- Sivan Kurzberg, Paul Kurzberg, Yaron Shmuel, Oded Ellner, and Omer Marmari -- were eventually deported to Israel. In a November 2001 interview on Israeli television, three of them appeared on a talk show where one stated: "Our purpose was to document the event." This statement raised questions about how they could have known to be in position to "document" an event that was supposedly a surprise attack.

The owner of Urban Moving Systems, Dominik Suter, fled to Israel before the FBI could conduct a follow-up interview. The FBI classified Urban Moving Systems as a "suspected Israeli intelligence front." Declassified FBI documents released through FOIA in 2005 revealed that the investigation was more extensive than publicly acknowledged, though an FBI field report stated that "none of the Israelis had any information on prior knowledge regarding the bombing of the World Trade Center."

ABC News' 20/20 program ran a segment on the case in June 2002.

The DEA Report: Israeli "Art Students" Spy Ring​

In 2001, the Drug Enforcement Administration compiled a 60-page report documenting a pattern of Israeli nationals approaching and attempting to enter US government offices and the private homes of federal agents and intelligence personnel, posing as art students. Approximately 140 Israelis were detained in connection with this operation.

The DEA report noted that many of the Israelis had military intelligence backgrounds and that their activities followed a geographic pattern that in some cases overlapped with locations where the 9/11 hijackers were living or operating. The respected Paris-based intelligence newsletter Intelligence Online published details of the DEA memo on February 28, 2002. Salon.com published a detailed investigation titled "The Israeli 'Art Student' Mystery" on May 7, 2002.

The DEA report went no further than to speculate that the "nature of the individuals' conduct" suggested "organized intelligence gathering activity." Whether this intelligence gathering was related to the hijackers or constituted a separate operation remains unresolved.

Carl Cameron's Fox News Four-Part Series​

In mid-December 2001, Fox News correspondent Carl Cameron aired a four-part investigative series on "Special Report with Brit Hume" reporting that federal agents were investigating whether Israeli intelligence had been conducting espionage operations in the United States and may have gathered advance intelligence about the 9/11 attacks without sharing it. Cameron reported that some investigators believed the Israelis may have been tracking the hijackers.

Cameron was careful to note that "there was no indication that the Israelis were involved in the 9/11 attacks" but that investigators suspected they "may have gathered intelligence about the attacks in advance, and not shared it."

The four-part series was subsequently removed from the Fox News website. Fox spokesman Robert Zimmerman stated the piece "was up there on our Web site for about two or three weeks and then it was taken down because we had to replace it with more breaking news."

Odigo Instant Messaging Warnings​

Odigo, an Israeli-owned instant messaging company with offices in Herzliya, Israel (near Mossad headquarters) and in New York City, reported that two of its employees in Israel received anonymous instant messages approximately two hours before the attacks warning that "something big was going to happen in a certain amount of time." The messages ended with an anti-Semitic slur.

Haaretz, the major Israeli newspaper, reported the story on September 26, 2001, under the headline "Odigo Says Workers Were Warned of Attack." Computerworld reported on September 28, 2001, that the FBI was investigating the messages. Odigo identified the originating IP address and provided it to the FBI. The sender was never publicly identified. Odigo was later acquired by Comverse Technology, another Israeli company that was itself the subject of federal investigations.

ICTS International: Israeli-Founded Airport Security​

ICTS International N.V., a Dutch-registered company founded in 1982 by former members of Shin Bet (Israel's internal security agency) and El Al airline security agents, controlled Huntleigh USA, the passenger screening company responsible for security at both Boston's Logan Airport and Newark Airport on September 11, 2001. United Flight 175 and American Flight 11 departed from Boston Logan. United Flight 93 departed from Newark.

ICTS acquired Huntleigh USA in 1999. The company's controlling shareholder was Menachem Atzmon, who held over 60% of shares through a family trust. The fact that an Israeli-founded security company was responsible for screening at the airports from which three of the four hijacked flights departed has been noted by researchers, though no evidence has been produced linking ICTS personnel to deliberate failure.

Israeli Intelligence Warnings to the US​

In September 2001, the Daily Telegraph reported that Israeli intelligence had passed two specific warnings to the US about a large-scale terrorist attack in the weeks before 9/11. Mossad reportedly warned the CIA that a cell of up to 200 terrorists was planning a major operation, though the warnings did not specify the targets or method. These warnings were among many from multiple foreign intelligence services that were not acted upon.

Key Figures​

  • Christopher Bollyn -- Investigative journalist and author of Solving 9-11: The Deception that Changed the World. Conducted extensive research into Israeli connections to 9/11, including ICTS International and the "art student" network.
  • Alan Sabrosky -- Former Director of Studies at the U.S. Army War College. Publicly stated his belief that Mossad was involved in the 9/11 attacks, citing his military intelligence background and analysis of the evidence.
  • Carl Cameron -- Fox News correspondent who aired the four-part investigative series on Israeli intelligence activities in the US related to 9/11.
  • Sibel Edmonds -- FBI translator and whistleblower who has referenced Israeli intelligence activities in connection with pre-9/11 intelligence failures.
  • Philip Zelikow -- Executive director of the 9/11 Commission. Critics have noted his close ties to Israeli policy circles and his role in shaping what was investigated.
  • Susan Lindauer -- Former CIA asset who has discussed foreknowledge of the attacks from multiple intelligence sources.

Criticisms & Counter-Arguments​

  • FBI findings on Dancing Israelis: The FBI field report concluded that "none of the Israelis were actively engaged in clandestine intelligence activities in the United States" and that Urban Moving Systems was a disreputable company employing men without work permits but not an intelligence front.
  • Anti-Semitism concerns: The Anti-Defamation League and other organizations have characterized the Israeli foreknowledge theory as anti-Semitic conspiracy theorizing. Legitimate criticism of Israeli government intelligence operations must be carefully distinguished from anti-Jewish bigotry.
  • 4,000 Israelis claim debunked: The widely circulated claim that 4,000 Israelis or Jews were warned to stay home from the WTC on 9/11 has been thoroughly debunked. Israeli citizens and Jewish Americans were among the victims of the attacks. The Odigo messages went to two employees in Israel, not to thousands.
  • Separate intelligence operations: Some analysts argue that Israeli intelligence was indeed running operations in the US -- as it routinely does in allied nations -- but that these operations were unrelated to 9/11 and focused on other intelligence targets.
  • Warnings shared: Israel did share general warnings about an impending terrorist attack, as did multiple other countries. The failure to act on warnings is more plausibly attributed to US intelligence failures than to Israeli complicity.
  • Selective evidence: Critics argue that proponents cherry-pick evidence and ignore the broader context of intelligence failures from multiple agencies and countries.
