I think Weazel IS Osama Bin Laden.
It all makes sence if you think about it.
In the strikes against the Tora Bora complex, a USAF bomb must have sealed off the cave where Osama..eh Weazel was hiding. But they have food and water for several years, a good supply of air, and (unfortunately for us) a power source (presumably they hotwired a dirty bomb and made a mini-nuclear powerplant) a computer and an internet connection.
Now, unable to continue his jihad in person, Osama..er weazel has decided to take the fight to the bulletin boards of the world where he uses several aliases to fight against the forces of democracy.
I mean if you think about it, every BB has its own loon fighting his own private jihad against the US...thats just Osama under a different name.
