The discussion treats the shock of the 2001 attacks as a product of confidence that the United States was too powerful to face such a threat. Warning signs and security questions had existed, yet the assumptions of the period kept them from receiving sufficient attention. That gap helps explain why conspiracy theories flourish: people struggle to accept that hubris, institutional complacency, and ordinary mistakes can produce a strategic surprise. The historical-method lesson is to test whether forethought and malice are needed when inertia and overconfidence explain the outcome more directly.
