It appears the brain dead bin Laden hasn't figured out that you can only be martyred once. I can only recall one case of resurrection of a mortal...Lazarus and one of Jesus Christ himself. Neither of them were martyrs. Allah and Mohammed hadn't been invented yet.
Bin Laden was one of several men appearing and speaking on the tape. They include Abu Musab al-Zarqawi, the leader of al Qaeda in Iraq who was killed in a U.S. airstrike June 7, 2006. How big is al-Qaeda?
That dates the tape to a time prior to 6-7-2006 and probably after 9-11-2001. Pulling out archival tapes is hardly a "fresh" threat. It suggests there is no current leadership capable of formulating and communicating a threat at the current time.
