I lost a friend in this attack and I guess trying to make sense out of what happened. So far I like the response below seems the most believable to me
Why Murder Mountaineers at Nangaparbat? ... As you all try to make sense of these chilling coldblooded murders, in an area where such things have never happened, and where these "so called Taliban" generally don't operate you must remember the attacks on Srilankan cricket team..for Taliban or any religious group never had a position against cricket and attacking "brown Srilankans" didn't fit into usual Jihadi agenda...then why? How do we explain such madness that simply doesn't fit in?
The answer is: there is one hell of method to this madness; attacks on Srilankan team were done to ensure Pakistan's isolation from international cricketing, and attacks on Nangaparbat are to ensure end of "international mountaineering expeditions" ...but could all this be a "Jihadi Agenda" ?
You will soon hear and read lots of spin doctoring telling you of how Taliban were taking revenge of this or that, but don't be mislead, this is not Taliban, this is a "strategic regional mindset" that aims to ensure continuous isolation of Pakistan from international narrative; mountaineering expeditions provided oxygen of positive publicity to the country and a powerful strategic mindset does not like that...this is what Nawaz govt needs to take up with them behind the scenes...this is precisely the "terrorism" they need to stop before we can make progress on other issues...
