Osama would be probably dead because some other guy has replaced him for the position. Why? Al-Qaeda knows that operation has killed Osama. And there is a reason why U.S. didn't release the videotape on public. Maybe the main reason will be a retribution of his followers against U.S.
I think he is dead,because if he still alive,he should have announced it and show his self to the world that he is still alive,thus making the US government and obama put on shame. But up to now we heard nothing from obama which means he is really dead.
osama is dead and this topic is now old to discuss.he has not resurfaced again all this time so its quite easy to believe that the evil spirit is no longer in this world.all terrorist have same faith one or the other day.
