Well, I think they are trying to hunt him down, Dianavan, but I may be wrong. :-) I'll tell you why they're really in Iraq AND Afghanistan, though...oil and oil shipping routes, that's why. Strategic postioning in a vital part of the World.

Why would they want to catch Osama? It would be a nice feather in Bush's cap to help him win the election in November.

That's my theory.

On the other hand, keeping Osama on the loose indefinitely could be handy too...if they don't need him to win the election. It provides further excuses for further military adventures. I figure they can always find another bad guy if they need one, though. All it requires is a few months of lurid propaganda to get the American public all worked up...or another terrorist attack stateside. Either contingency could be arranged, I'm sure.
