Can't say I consider him a particularly big threat to world security anymore. I don't think he can become that again without toning down the secrecy a huge deal, and if he does that, he's probably dead meat. There are other terrorists out there who are now important to deal with, because they don't have to hide in a cave/compound/whatever all the time. I'd also like to know precisely what this "motivation" he provides is. The dude's obviously scum and it'd be great if we caught him (Though really, considering how many other false alarms there have been over the past few years this one probably isn't right either), but I simply don't see how doing so would really help solve any problems beyond "finding bin Ladin."
