There is such a thing as geographic determinism which regards geography as a major variable in shaping of peoples/nations. Kabul and all of north east Afghanistan [which forms big % of Afghan population] is actually a natural part of the Indus River region. The Durand line is as artificial, if in fact more than the Radcliffe line. It was marked by the British. Consider this. Whereas the Radcliffe divides Punjabi from Punjabi but they are differantiated starkly by religion. That is on one side you have Musim Punjabi and the other Sikh Punjabi. However in the case of Durand it divides Muslim Pashtuns from Muslim Pashtuns.
What I am saying is despite all the vitriol and hatred you see Pakistan and Afghanistan are conjoined twins. History has shown that. And for those who b*tch about Afghans don't ever forget the primary value given by USA on Pakistan is Afghanistan. It's not like we have oil or trade to offer them. When we croak about our strategic location we actually primarily mean Afghanistan.
Despite the negatives that members here heap on Afghans never it be forgotten some of the most precious assets we have acquired is thanks to us prostituting the Afghans. Think of all the F-16s, military aid we have got over 1990s, 2000s and MOST important of all the nuclear bomb
You guys think that America would have allowed us the nuclear bomb? Not in your wildest dreams. We got the nukes because we were fcuking the Afghans in 1980s to everything and anything. That included using the Afghan jihad as shield against US poking in our nuke project. Notice soon after Soviets left Afghanistan America hit us with Pressler amendment and our famous F-16s got impounded.
So next time you bitch about Afgans keep the nukes, the F-16s, Pakistan strategic value in mind. I am not saying there have been negatives as well but sans Afghanistan we would have been in far worse position versus India. No nukes for starters. We could have resigned to become Mata India's cub.
And as if to highlight it even in 2019 Pakistan's relevance in Washington as seen by PMIK's visit was Afganistan. Othewise we are just another bankrupt country. Furthermore don't think even if US pulls out Pakistan's value will go to zero. It will drop to a degree but US will leave this region and rely on Pakistan to make sure that Af-Pak region never becomes a threat for the West again. So Pakistan's relevance will continue into the next decade at least, although somewhat reduced. Again thanks to Afghanistan.
