Not sure I'd call Pakisatan an 'ally' anyway. Clearly, their security forces are doing very little, if anything, to work with the West. At worst, they seem to be colluding against the West. How else do you explain the fact OBL was living quite happily in a residential suburb in the country? Of course I suppose it could just be rank uselessness on the part of the Pakistani Authorities.

Wouldn't surprise me in the least if the attack had been authorised by Pakistani Officials.
