Hiya Bruce ... interesting, some responses.
Being ambushed is not what I had in mind by "finding the enemy". Finding the ones we want at time when we have the advantage is the trick. I also note you describe how hard it is to tell enemy from neutral later on; you seem to refute yourself.

Limited bombing... a long slow admission of pinpricks will piss someone off, especially if they are already disposed to resent you as a foreigner. Do you seriously think the Afghans wouldn't mind having their country (or territory, or area, whatever) bombed or otherwise struck at?

Howdy TW:
The thing that struck me in your post was the goal "to go after" Bin Laden (etc).
Going after them means we are always a few steps behind, playing catch-up as they recruit new suicide fodder.
The only way to defeat the taliban is to cut off their supply of recruits by shutting down their religious schools (Madrassas) and replacing them with reasonably good quality secular schools. But the taliban know this and violently resist modern education, so this approach wont work without extensive (international) security to protect all schools for a generation, and that is about as likely to happen as the run-off election producing an effective and honest government.
