This is what surprises me about western power's will to invade Afghanistan - its been done many times and always ends in defeat.
Listening to the news on the radio and watching the excellent English language version of Al Jazeera TV news its been made clear that the Pakistanis always believed our adventure in Afghanistan would end in defeat. Their policy has been to plan for what happens after that defeat. If that's "looking both ways" as David Cameron put it then it seems sensible enough from their perspective.
Bush might have said you're either with us or against us, but here on planet Earth its not as black and white.
