What I read is that he is an "orphan" of the jihad, a leftover from the fall of the Taleban. In that regard, I suspect nobody gives a damn about him on either side. That is why the Paks chose to take him out. They can be seen by the Americans as doing something without being directly responsible for undoing the jihadi big boys.
I suspect that if we get really good intelligence about OBL or AZ we will be handling it ourselves. I doubt that it will matter which side of the border they are on. We are going to wax them by any means necessary.
