Believe me NATO is no longer that way anymore they are now more worried about Russia + China hence amassing in Europe and NATO is a spent force with limited ground force available which is why their money spent on ANA's ghost soldiers speaks volumes for their incompetence. We share the biggest border with them and they are landlocked even with chabahar and Iran becoming their route for groceries can never replace the fact we have the largest border and the highest number of their countrymen staying in Pakistan.
But the best approach in my humble opinion is to follow the method that rooted out and destroyed Pablo Escobar by having a Militia that can hunt NDS+RAW terrorist in afghanistan ruthlessly, No need to military to step into afghanistan at all!!
But all this is fairy tales for as long as noora,taki,diesel and anp are not dealt with first.
