Re - "......This same strategy was used in Egypt with some success until the Egyptian people rose up and stopped it. This will take tour operators, drivers, hotel owners, restaurant operators and guides to rise up and stop the violence by reporting the activities"
True that Egypt suffered, but I would suggest that the two nations are really very different in how big and crucial tourism is. Egypt was losing 'big' time because of how central tourism is there, and how famous as a destination it is and has always been, enough to get people angry enough and united to take a stand in the way you mention.
Plus they had Mubarak's Mukhabarat who had been 'directly' countering and squashing Islamist politics since inheriting the security framework from the British, so even if there were sympathys for militancy it would soon rooted out by that. Pakistan's ISI is arguably far less clear cut about where its interests and loyalty lies, it would seem.
In Pakistan, I'd argue that international tourism is absolutely minor in comparison to Egypt, and generally the locals have far more important things on their mind even though yes I'm sure most are just as horrified by these events.
Motivations for attacks in Egypt during the 90s and later in the 00s were pretty different from say this latest attack, seen as a revenge attack for a loss to them during an ongoing war. In this latest attack in Pakistan, the explanation was that it is a direct revenge attack for the loss of a commander in a drone strike. Events over the border after the invasion have led to bad feeling in parts of Pakistan, enough for suggestions that there are elements of complicity and sympathies going on in some institutions and within the people of some areas, to not sound unreasonable.
