I agree, I dont expect it to happen as Pakistan's long-term stability isn't guaranteed at present. In fact the new nuclear deal with India may be a kind of insurance policy for the possibility of Pakistan descending in to any kind of political turmoil in the future. I do think, however, that Pres. Musharraf still has a lot of leverage with the U.S. administration, though whether this will be the case with the subsequent administration is unclear.
