Here are a few stingers...
* These borders will cost each and everyone in their due time and a just punishment... and the reason is not what you may first assume.
* Those who devised these borders for you used your territory to an otherwise landlocked state for a war of aggression and imposition of their, otherwiseprevalent paradigm in Pakistan, they failed!
* Those who they will have the last laugh by deporting Afghans, mark my words, they(the Afghans) be better off than Pakistan in coming decades... again knocking on these borders and Pakistan will be able to do jack about it... pinched between the two, on borrowed time, running a western paradigm on their dime! With India on one end, Free Afghans on the other, an Iran running it's own foreign policy and lastly an ascendant China that wouldn't need Pakistan. Rue the day!
* A colonial project can only last that long or the ones living there will all emigrate to foreign lands for greener pastures. It is better aping an Englishman in England then a forsaken back water... where perhaps an Englishman may appreciate the coy mannerisms and efforts employed at larping him/them!
* The conflicting, prevailing ideologies that were at loggerheads back then were communism/socialism and consumerism/capitalism... remember like Afghans... Pakistan had it's iterations in ANPs, PPPs and assortment of Baloch parties.
* Just as Arabs were caught with their pants down when one end of the political spectrum caved in the form of Soviet Union... the whole region paid the price... the rest don't even know who or what they follow. And one thing both those ideologies had in common was preservation of the zionist project! Yet Pakistanis continue on that autopilot ... well now at least they wouldn't have the excuse, no one told them!
Sun will set on Pakistani demographics, and that will be a sour burden on vultures enjoying an easy meal today... tomorrow they'll eat each other!
