Anyway this for Pakistanis to decide. I being an Indian and you being an expat can only presume and assume.
What did Americans achieve really in Afganishtan? It's not like Pakistan put a gun to their heads did they? They knew the game being played and went along with it. 9/11 needed an example to be made of Al Qaeda and Taliban. That was the purpose of Afghan campaign.
The American public needed to see the tanks rolling, jets zooming, arty thundering and they got the whole dog and pony show. I dont think Americans seriously care what happens to us primitive S. Asians. Only thing which scares them yellow are the Pakistani nukes and for that they will give Pakistan the moon if it wants.
