I think Government should give Mushi a way and let these Pawns die a natural and miserable death. This is not the time to escalate tensions. Government should focus on its economic agenda and leave no future space for any Musharraf. Get him out, get him declared convict and close his chapter for good. With musharraf gone TuQ and Pawn khan will die the next day.....
Civil war is still a very extreme possibility, the best policy for the government should be to restrict the TuQ to Lahore and strand Khan in Islamabad. With every passing day, Pawn will become more and more desperate, so will be the support of people as they will grow tired of protest. Result will be that Pawn will be forced to take a desperate measure providing government with golden opportunity to weed out this noise for good period of time.
