It’s the NYT hopping on the Howard Dean bandwagon and nothing more.
So the information was old. New information gathered in the Khan arrest in Pakistan may have helped analysts see the old information in a new light. Remember that planning and surveillance for the 9/11 operation went on for 2 years (according to the 9/11 commission report). Ditto for the embassy bombings in Africa. What isn’t highlighted in the NYT piece – but is mentioned in passing – is a DHS official saying the old information “may have been updated as recently as January.”
Suggesting that this is a political ploy allows folks to diminish the importance of the war we’re fighting. Continued dimunition of its significance contributes to complacency and complacency will get us killed.

On Today Bloomberg reiterated that some of this was old information–as he had previously stated–but reiterated that there was additional data that came to the fore Friday, thus the alert.
