Where did you hear this? Do you suppose there might be joint Paki/U.S. actions in the Paki "Tribal Territories" (where a bunch of the Al Qaeda from Afghanistan, conceivably including Bin Laden, are probably hiding out)?
If Musharref wants to control events in Pakistan he is going to have to deal with the problem of the tribal territories. Of course Pakistan has never controlled that region before, and it will be damned tough and costly to assert that control now...
