Of course, it is always the best to stay on topic, and stay focused.
See, I raised the point that the US is not uninvited, because that point holds a key that unlocks the door to every player in the region. India too has been injured because of Taliban's free, though wild, hand in Afghanistan. And US and India are not the only countries that a wild Afghanistan had effects on.
In essence, I personally feel that resurgence of any similar government in Afghanistan will be beneficial to none, even though desired very strongly by some in Pakistan.
So you see, it is not just about whom you need and whom you do not need. And the gains and relations, my friend, are not related just 'location-religio-cultural-historical' affinity. These are just romantic terms ushered to calm public opinion in the ally countries.
If those term ever held any water, then Iran and Saudi Arabia would be closest of allies. India and Pakistan would be very close "friends". India would have a proxy in the form of Guyana and Surinam. Etc etc etc.
The hard truth is, allies and friends find each other when the goals are mutual, when there are needs and purposes and consequences to serve and affect both the parties same. Historical/religious/geographic affinity rarely ever have a say in such matters.
