1. Simple reason, the higher the number of targets, the higher the drone strikes. Plus the prime objective is to take out AQ & the foreign militants, which are mostly located on this side as they can't mix up with the locals on the Afghan side. Thus they have come on this side, but they are being hunted down with the help of the ISI, plus in some instances CIA using its own resource, which by the way mostly results in civilians targets.
2. NATO has the power, thus it rants. Their media is on their side, they have influence. But if you are truly looking for knowledge, why don't you do some Googling and see what is happening on the ground. Who has more troops, who has lost more troops, who has more border check posts compared to each other. Why don't you Google about the presentation given by Kiyani to the NATO high ups right in Brussels HQ of NATO. Kindly do it, and hopefully if you look at it as a neutral member, you may see who is doing more. But if you looked at it as an Indian, well i guess i don't have to say what will be the outcome of your analysis.
3. Plz read history, these AQ men are the same ones who came in the 80s to this country to fight someone. The spent years and had local support of intel agencies as well as ordinary people who had gone there to fight the soviets. The got married here, started to live, had friends who shared the same objectives & views with them. So that is why they had chosen Pakistan as they had support from the people. Same case for the Taliban, all these men have lived years inside Pakistan and in Afghanistan. Even current Afghan president spent years in Pakistan, i believe his dad also got killed here. We have no visa system, anyone can cross over and back without needing any passports or visas. Its an open border.
4. If someone has sympathy with AQ/Taliban based on their views, be in military or outside of it, then you need to see the reasons for that. Do think and see why majority of the Muslims hate the US. I myself hate the US, but not its people, rather its policies and the ones who carry those policies. To Muslims around the world, majority of the ills happening to the Muslims is directly attributed to the policies of the US. Thus, people serving the military are human beings and Muslims, their minds also can get influenced if the religion card is played. They are also seeing what the US is doing, supporting Israel who got created with the expulsion of Muslims from their land/homes, what Israel is doing with Muslims with the active support of US, support of dictators ruling Muslim countries, launching wars on Muslim countries.
5. The people in Afghanistan are fighting the occupiers, they are not in Pakistan. In Pakistan you have your own groups which have their own agenda and are terrorizing the people in the name of the religion. Sectarian violence and other objectives behind it. As said, they have different objectives/agendas and using religion to their like. Some militants cross the border and live there, while some cross the border and live here. The ones who are being hunted down in Afghanistan get support on this side of the border and those who are being hunted down on this side of the border, get support on the Afghan side.
6. And yeah, we are still having friendly relations with the Taliban, that is why US/NATO are crying / whining to attack them. The so called taliban which are attacking Pakistan are not those Taliban which we used to have as friends, they are someone else. And not all strategic assets are burst, many of them are still being kept as strategic assets, just wait for a while.
