@trim101 - I thought you might say that military targets would be the way to go, and to some degree I agree, it's certainly at least closer to, or more, justified than deliberate attacks on civilians.
But he has, and continues to try to, attack civilians. So what do we do about it?
I don't have an easy answer. I do think that reforming foreign policy is certainly a step in the right direction. Meddling less in other countries internal affairs, supporting bad governments less, increasing targeted aid that helps ordinary people, and generally trying to be more cooperative with the rest of the world would certainly do a lot to decrease the number of people who would get drawn into the orbit of someone like Bin Laden.
Certainly also, the majority of terrorism fighting should involve international intelligence and police actions more than straight military actions, but I honestly do believe there is a role for military strikes in fighting people like Bin Laden, and as much as I'd love to live in the world you talked about earlier where no country has a military, we don't live in that world, and some form of military is necessary to keep civilians safe.
