The September 11, 2001 terrorist attacks in the United States were orchestrated or facilitated by individuals or entities within the United States government.

The Short Version

Every major official investigation into the September 11 attacks — including the 9/11 Commission, the Department of Justice Inspector General, and NIST — concluded that the attacks were planned and executed by al-Qaeda, finding no evidence of deliberate orchestration or facilitation by U.S. government actors. Documented intelligence failures were characterized as systemic bureaucratic shortcomings, not intentional enabling. Reframing institutional incompetence as "facilitation" conflates negligence with deliberate action, a distinction the official sources explicitly draw.

Caveats

The proponent's argument relies on equivocating the word 'facilitated,' treating unintentional bureaucratic failures as equivalent to deliberate government enablement — a distinction the official investigations explicitly reject.
No credible, independent investigation has produced evidence of U.S. government actors intentionally orchestrating or enabling the September 11 attacks.
Public belief in conspiracy theories (as measured by surveys like Source 11) does not constitute evidence for the factual truth of those theories.

More Fact Checks

Before September 11, 2001, the Central Intelligence Agency and the Federal Bureau of Investigation were aware of a specific threat to the United States involving the individuals who carried out the September 11, 2001 attacks.

Before September 11, 2001, the Central Intelligence Agency and the Federal Bureau of Investigation knew that individuals involved in the 1993 World Trade Center bombing were taking flying lessons, recruiting people, and conducting surveillance flights, and the agencies did nothing to stop them.

The National Commission on Terrorist Attacks Upon the United States (the 9/11 Commission) reported that it found no evidence that the U.S. government had foreknowledge of the September 11, 2001 attacks.
