The almost total absence of senior al Queita leaders captured...and if the "brains" survived...remember, they use doubles...the family of the "brains" was whacked in an air raid. Osama's sons apparently escaped, as well as Osama's three wives.
IMHO, we are up against it. Next attack?? Probably Bio...my guess Smallpox. It is present in the soil of old graveyards, and that outbreak happened about 20 years ago. I still think the DOWNFALL operation is to be put into effect, or perhaps the Daschle Anthrax could be released.
It Isn't over!!
