You know what I feel, when It comes to making Pakistan's foreign Policy there are no right decision, some decision might seems right at the moment or for the time being but eventually we are like, wish we had/had not have done it or etc...I think Pakistan fate and future was change the day we decided to go nuclear and since then major Power are constantly trying to destabilize it one way or another...
Iran, many don't want to accept is extremists Shia and their sectarian ideology drive their Policies for creating allies and enemies on a worldly scale, Yemen and Syria are prime example of it, they are just as you said with India try to keep this dead Panjshir resistance alive or some pockets of resistance from Tajikistan, to make sure that Afghanistan and Pakistan remain unstable, unfortunately our Habibi's in GCC will look at us and remind us about the Alliance they were so eager for us to join, but it all comes down to that when it comes to
Pakistan there are no right decisions.
