Doesn't matter, if the Central Intelligence Agency failed to get him out or failed to convince him that the lives of him and his family would be in extreme danger then they failed.
As was already mentioned, this is now front page news, try to get another Pakistani doctor, lawyer, general, etc to assist the United States again, ain't going to happen. The Central Intelligence Agency made damn sure of that.
He should have been given a few million a house in San Francisco and a new identity.
