Ayman al-Zawahiri, the #2 of al-Qaeda, has issued a tape denouncing Obama. The headlines have screamed "racial slur!" and the "official" translation had him describing Obama as a "house negro." The actual term was "abd al-bayt," which literally means, "house slave," not flattering, but not a racial slur, and also inaccurate, given that he is about to become the house master, arguably, something that makes the al-Qaeda crowd unhappy.
Now while Obama has promised to go after Osama, I think the fact that al-Zawahiri has been doing these tapes since 2004 with no appearances by Osama means that the latter is either incapacitated or dead. If dead, I can see them keeping the illusion of him still alive going. Although they are Sunnis, this sort of resembles the Shi'i cult of the missing 12th Iman, who supposedly went into Occultation and will reappear in the world as a messianic savior at some point, with various current leaders claiming access to him. Osama could be the radical Sunni Hidden Imam, with Obama chasing a Hidden Imam Osama.
