== Pakhtunwali is not a religion == 
 It's a custom, and it is not universal in this area. Ask the average Pakhtun what his religion is, and you will almost certainly get the answer, "Islam" 

 == Joined Pakistan by popular vote == 
 Even though the political leaders were against it, the population voted overwhelmingly to join Pakistan. 

 == Durand line: not that arbitrary == 
 For some of its length, it runs along or near the ridgelines of the mountains that divide Pakistan from Afghanistan. Although it divided the Pakhtuns, it was in some parts a reasonable place geographically to put a border.
