Why are you so scared? Iran is also Afghanistan's immediate neighbour. They have remained out of this war OF terror. Why get ourselves involved and make so many sacrafices which is not in Pakistan's interests in the first place. Extremism and terrorism has grown since Pakistan involved itself in this war OF terror.
Dont be scared of America. Republican or Democrat every political party in U.S. has become anti-pakistan and anti-iran. They cant afford another war so they will just talk. Pakistan needs a lion like Ahmedinejad, not small pet cats like Zardari and Nawaz.
Ahmedinejad sleeps on the groud and even when U.S. placed sanction on Iran he put his country before anything else. Imran Khan is similar. Imran Khan slept in the streets trying to stop drone attacks. Pakistan will never find any political leader like him.
Pakistan doesn't want to be seen siding with terrorists/extremists, they will not only make Pakistan unstable, but they will also result in the isolation of Pakistan worldwide, including friendly nations like China, Turkey etc. The economic & political ramifications would be too great, so instead of a hot headed approach of getting back at the US, we need to think this through better. I agree that the costs of the WOT have been too high, but siding with terrorists/extremists is never an option.
