911 was an inside job

Contradicted by strong evidence

What we can confirm

Authoritative investigations and extensive evidence show that the September 11, 2001 attacks were planned and carried out by al‑Qaeda terrorists, not by the U.S. government or other domestic actors; the broad claim that “9/11 was an inside job” is therefore false and has been repeatedly debunked as a conspiracy theory.
