Afghanistan can never be a free and independent nation because it is land locked.
Land locked countries either die and get absorbed by others around them or become vessel states like Austria, Luxembourg and Central Asian states etc etc.
Pure and simple Afghanistan needs Pakistan more than Pakistan needs them. This will never change.
The quicker you understand this reality, the quicker you can can come back down to reality and see that Afghanistan is a failed concept which is in the process of dieing. It already has died many deaths. Since the beginning of the 20th century Afghanistan is slowly but surely developing into a land of destitution with no signs of progression.
A nation needs access to ocean, a common cause and sanctity for life. Afghanistan has none of these.
Pakistan Pasthuns have nothing to do with Afghanistan just like Pakistan Punajabis have nothing to do with Indian Punjabis.
You morons from Fata still have not come round to this concept and are bending over for Afghans thinking they are family. They are not your family, they are here to dominate you just like ttp, Taliban and every other Afghan who despises Pakistan.
