Perhaps very little damage will be done to Taliban and ultimate sufferers will be innocent people. Which will inturn create more Taliban as usual. The more you suppress, more will come out with strong force. I think best policy is to restraint and negotiate rather than using of brutal force.
As regard NS or Zardari, I think matter is above their intelligence. Only ANP, JI, IK and Maulana Fazal can play a vital role to save innocent human lives.
I know I said cluster bomb and that usually covers a larger area, however I meant to suggest to bomb only the location where they are holding hostages, if all hostages are killed by Taliban- God forbid- then just track their locations and bomb'em/target-shoot them.
