I don'tthink you still understand. You must admit my thoughts on this subject have been validated. I at times was the lone voice here. The minority. But you overlook something. Never use PDF as measure of the real Pakistan. Do you really think PDF represents the real demography of Pakistan? It represents either ex-pats with internet connections or Pakistani's from the better economic segments of society which is mostly urban. Karachi, Lahore, Islamabad and a few nodes in between. The cyberspace gives you a skewed view of Pakistan.
And you still are slave to the Gangatic view of the region. The Indus basin is not and has never been the preserve of one homogenous ethnic group. The Indus Basin is the fracture zone between the west and east. It's history has been defined by that. Two currents spilling into Indus for millenia. It has always been a set of two. Where the West converged with the East. You can go as far back as Mehr Garh or Gandhara, Taxila you will see the west and east creating a syncretic civilization. To be sure the tide kept shifting but the 'gateway' aspect always existed.
What you did and many like you is get entirely absorbed with the reality of the previous century which of course under the British rule saw Indus becoming locked with the east - the Ganga Plains but 1947 undid that. So in a sense we are merely seeing the re-adjustment to the status quo that prevailed in history. Imean look at the Afghan Empire. What you call 'Indic' is firmly part of a westerly based empire. And this pattern goes back to Persian, Greek, Kushan times. However if your template is the British Raj then I can see why you have a problem understanding this concept of Indus as a unique - in that it is convergence of civilizations. And has always been that. From the Gangatic POV, same but annoyingly detached and differant. From Iranic POV same but with annoying accretions that were differant. We are the Anatolia of the east. A bridge between west and east and I would argue even the north. CPEC is in fact the historical reconfiguration of the silk road that saw Bhuddism travel north from Taxila to China.
