Do you think he is really dead?

This is the 12th time he has been reported dead, (the other times we just killed innocent people that looked like him) Not to mention the fact that we don't have his body because we through it into the sea, and i have yet to see any photographic (or otherwise) proof. Is it vaguely possible that we might just have the wrong guy again? And even if we did, this brings us to the question, what did we gain from this? The terrorist organization is still out there and they will just find another leader, not to mention the fact that they are now pissed at us.
