Neither the determination of al Qaeda, nor the tactic used in this incident seem particularly shocking or new. Perhaps this kind of thing has something to do with a news search for "Napolitano" today bringing up three calls for her resignation.
Napolitano's answer. Watch the video, here.
I think, following up on that, not just the determination of al Qaeda and al Qaeda Arabian Peninsula, but the tactic of using an individual to foment an attack, as opposed to a large conspiracy or a multi-person conspiracy such as we saw in 9/11, that is something that affects intelligence. It really emphasizes now the renewed importance on how different intelligence is integrated and analyzed, and threat streams are followed through. And, again, it will impact how we continue to review the need to improve airport security around the world.
