agree with Willemspie, Taliban is enemy of Shia muslim. no way can reach there..or attack..death to America and Israel signs in Iran, Turkey and where it not, do the tourist do not visit there? this signs are there over 20 years but people serving tourist there.

I'm in a similar position...
Do you ...or Don't you?
To the rational, the answer would seem obvious...Don't go.
Its probably not the place to discuss philosophical question as to why ...
However, examining the situation a little more thoroughly, the probability of an unsatisfactory outcome is probably no greater than it was before NP murders.
In an attempt to quantify the risk, I am enquiring of operators how many groups have cancelled ...so far significantly more groups are proceeding than cancelling.
I have also received a copy of a statement from the Gilgit-Baltistan Government categorically stating that protection of foreigners is paramount and has been significantly enhanced by the local police and special branch departments.
A 24/7 information cell is also being set up which may provide more information when it is established.
I shall continue to make plans, albeit a little more pedestrian than usual, and if it appears more people are going than cancelling, I shall go, taking a few more precautions than I normally would in risky areas.
May I suggest the more people go, the safer it will be...rather like the wildebeest migration......

Yes, I might have agreed with the 'wildebeest' analogy if I hadn't just read a blog on the website of three climbers from the Polish Alpine Club who fortunately were higher up Nanga Parbat when the attack occurred (nanga2013.blogspot) saying:
"Our expedition is over. Currently we are trying to get our equipment, which remained at Base Camp, to return to Poland. Unfortunately, it is not easy because of Pakistani support agencies leave much to be desired. Also the support of the government is very weak. Everybody who plans to climb a mountain in Pakistan should rethink their plans, because the Taliban officially informed that tourists will be targeted in further attacks. It should also be noted that it is a complete change in their terrorist activities, because so far no attack was done against foreign tourists. Prosecution of the murderers is very difficult, because the current Pakistani government is sympathetic to the Taliban."
Just quoting the opinion of some of the climbers who narrowly missed being attacked that night. Having been in the area myself earlier that week, I'd tend to agree that 'support of the government is very weak' - the frequent check-points where police/military personnel delayed innocent tourists in possession of valid passports and visas for up to half an hour while they 'phoned their superior officers for permission' just seemed like ticking boxes, rather than a serious attempt to intercept terrorist activities. I think I'd rather be a wildebeest taking my chance of being shot in a crowd, than a tourist in Northern Pakistan.

Yes, is it worth it? Non-refundable flights is one thing, but do you seriously want to risk your life?
Even after the tragic incident at Nanga Parbat BC,many foreign travelers still visiting Pakistan as well as K2 BC.

I've just read an interview in a Polish weekly with those who survived the massacre only because they were higher up on the mountain of Nanga Parbat. They are very experienced people, more than any of us. The man who led the Polish group had been in about 90 expeditions to Pakistan's mountains before it happened.
They've cancelled their plans for winter climb to the summit of NP as well as a few 6000m peaks in Hunza region that they planned to climb later this summer/autumn. Furthermore, he says anyone who's planned to climb or trek in the region should revise their plans. No trekking agents can guarantee security for activities of any kind in the area.
Ahmet Marwat, the spokesment of Jundallah, the local terrorist fraction, informed in a telephone interview with Reuters that there will be more such incidents in the nearest future, like the recent one at NP. He added, that all foreigners will be treated as their enemies.
I've already dropped all the speculations and made up my mind to cancel my trip. This post is for others who are still in doubt.
