A dutch Journalist has done the actual investigating, and proven the western "Intelligence" to be a total sham. The Taliban doesn't exist as this ever present threat; Afghani society simply isn't anywhere near that unified. Even much of the Haqqani network has fallen apart.
Nevertheless, it is nonstop tribal warfare; a thing which no outsider should have anything to do with (and could not possibly make any better).
How about this one: What if government gave everyone a receipt with an itemized list of the goods and services they have "provided" to us? If they did, the majority of the charges would be clear fraud if they were stupid enough to actually be honest in putting together the bill. Yet another feather in the cap of non-monopoly, private governance.
