I remember Bin Laden making a statement that he had nothing to do with the attacks on 9/11. But that was then; this is now. He wants us to fear him, I think that may well be part of his undoing.
He's a sick man if the stories about his needing dialysis are true. How long can he last? My guess is there are no recent videos of him because he looks like shit, is very sick, or even dead; may Allah will it.
