Pakistan should learn it's lesson and follow non-aligned policy in Afghanistan I think it's time to let go and abandon all proxies even Afghan Taliban did not accept Durand line. If we keep interfering they will only continue to blame us for everything it's such a harsh and tribal place with nothing to offer no benefits to having a close relationship. Afghanistan sadly does not even have any achievements or positive attributes as nation (seriously not being rude but I genuinely can't think of anything positive or successful that has come out of the modern state of Afghanistan if I'm wrong can anyone name some ? ) it's famous for nothing but drugs and Bacha bazi even so called rogue state Pakistan has at least few things positive come from it -2 Nobel prize winners,only nuclear state in Muslim world, multiple times world champion in squash,hockey and cricket,produced world famous musicians and first Muslim country to elect a female leader .
Pakistan was arrogant and insane to immerse itself in the name of strategic depth in such a failed state what the hell where they thinking ! From the start they hated us and we should have run in the opposite direction. Detach ourselves as much as possible yes have diplomatic relations but minimize contact, maintain strict border control and let them deal with their issues among themselves and stay our of their business .
