From the vibes I get from IEA perspective, they want to rewind time and wish for relations between Pakistan and Afghanistan to return to the friendly ties before 9/11 with people crossing freely between the 2 sides during their previous rule. Taliban in their 4 year rule before 9/11 never challenged durand line neither we had any issue that compelled us to fence the border. They do not claim our territory but rather want free movement between the 2 sides.
From our perspective all in all what I see is an opening for Pakistan and IEA a defense pact and the willingness of IEA to collaborate with Pakistan on intelligence operations and combined joint operations to get rid of any destabilising factors in the short-medium term. Once peace is established with hostile actors that threaten peace taken care of, in the longer term we can work towards free movement (or visa on entry) through the border crossings, this will address the Taliban concern/reservation.
They need help and support and in return they will keep their promise of protecting and not letting any form of proxy warfare against us, basically securing our back from a military point of view and enabling us access to central Asia from economic/commerce point of view.
