In that movie, the soldiers who took over the prison only did it to get them what was due rather than with hatred against the people. The general never had the intent of killing or harming the people in real but only were bluffing.Long back, I watched a film, The Rock. It was about a similar kind of blackmail using chemical weapons by a group of ex-soldiers who took over the world's max security prison. One of the best dialigues of the movie was, "We tried bluffing them, they called off our bluff, let us now wind up".
Same is true about Pakistan, they have used this nuke threat for far too long and now its time to call their bluff. In that movie the US govt decides to use thermobaric bombs on the prison and roast/vapourise everyone inside including the hostages.
This is never the case with Pakistan. Pakistan and Islamists in general are extremely evil and have full intent to cause maximum harm. There is no other way other than to keep sufficient reserve and preparation to take some losses for greater good
