These structural compromises and procedural failings converged to assure that the Commission would not challenge core elements of the “official story” of the 9-11 attacks. This failure was compounded by the Commission's desire to produce a final report that would read as a “historical narrative” rather than as an exhaustive set of findings on the critical unanswered questions that arose after the attacks. The Commission's unquestioning acceptance of the official narrative also meant that it missed a perhaps larger opportunity to challenge key myths associated with American exceptionalism. Thus, the 9-11 Commission ultimately functioned as an instrument of cultural hegemony, extending and deepening the official version of events under the guise of independence and impartiality.
