I tend to agree with your post overall. But I don't think there can be complete 'peace' in Pakistan--far from it--so long as there is the India-Pakistan rivalry with the U.S backed India/Afghanistan around Pakistan. These are two loooong borders with combined deep pockets--too much for a soft-state like Pakistan to fully handle.
And to have that kind of terrorism-free environment, one would need to go back to the Pakistan before the Soviet invasion of Afghanistan, as a benchmark. In those days (the pre 1980 era), there were occasional Shia-Sunni riots or some other ethnic/sectarian violence but there were never the blowing up of suicide bombers or mass, random targeting of civilians such as those started after 1980.
What started in 1980 had only ebbed for a brief periods but they never stopped. And they are still ongoing.
