U.S. intelligence had uncovered numerous "red flags" prior to the attack, Obama said, but failed to connect the dots.
The government's inability to stop the attack does not represent a failure to collect intelligence, the president argued. Rather, it represents a failure to integrate different intelligence strands.
The fact that intelligence was not fully analyzed, Obama said, is unacceptable. The president called for reforms to prevent such an incident from recurring to implemented immediately.
Obama reiterated, however, his intention to close the detention facility at Guantanamo Bay, Cuba.
