I don't think, with all due respect, that you are getting things in the right perspective. If you are mixing Taliban of Afghanistan and TTP, then you are seriously mistaken. Taliban of Afghanistan do not show any disdain for Pakistan, TTP does and it has different reasons, embedded in the Supreme Court's decision of 1996, which annexed the areas of PATA in NWFP/KPK.
Liking or disliking Pakistan depends on which side of Afghanistan you live and from which ethnic group you belong to. Obviously, Pakistan got involved in Afghanistan Jihad in 1979, when one group over there was already backing up Russians. So, the people who fought against Russian occupation do not dislike Pakistan. But people at the other end of the spectrum don't like us obviously. They like India for the reason that it had been pouring in money into that war to go against Pakistan.
This can also be observed through the fact that only Pakistan was able to bring Taliban of Afghanistan on the negotiating table with US and Iran. It means, they have some regard for us, for still supporting the Haqqani network against US's will.
Quite insipid, but at that time, when US was all charged up, it wouldn't have been wise to be like Iraq, Libya, Syria or Yemen.
Now that US had been exhausted and mellowed due to protrusion of these wars beyond a rational timeline, we have gained the audacity of saying "Absolutely Not". It is just anyone's guess that in 2001, US's plan was different as well as its economic and military might, supercharged by the stir of popular sentiment of its polity. The outcomes of saying "Absolutely Not" meant to push Pakistan into an abyss along with Iraq and Libya. What makes people think that at that time, US wouldn't have lined up Pakistan with Afghanistan for not supporting the WOT passively? at the best, we would have been made Iran and perhaps this war would've been having a different outcome today.
Pardon, but I cannot make up that how will Taliban be having an upper hand over Pakistani establishment? From the developments, it is evident that certainly Pakistan has an influence on Taliban, at least just enough to bring them to talks with US, Iran and China.
Yet, what worries me is that severing ties with US can put Pakistan into an awkward and sheepish position in front of China, for its defense, technological and economic development. I have seen the systems of China and the general psychology of the populace. It seems far from possible that we can get integrated with them harmonically. It will be too much of a pain and we also do not want to live out as a satellite estate of China as well.
Pakistan should not burn its boats and play every card up its sleeves right now. We should maintain a bargaining position between China and US and see what is better for our own objectives, strategy and values.
