Pakistan has it's self in a bind, they ignored Taliban / Al Qaeda while it was convenient and now they are too strong not to ignore; of course the question is what are they going to do about it.
We have to remember that Pakistan was a dictatorship and now it is kind of like a democracy. They are making some nominal steps and the terrorist are feeling the pressure; so they are trying to take it off by putting pressure elsewhere. The thing to do is not let this incident be effective.
