Lol. You Indian turd, do you even know the political history of Pakistan Afghanistan region? If there is a so called Punjabi issue within the dominion of Pakistan, multiply that by 100 and you got Pakhtoon and Farsawan issue in Afghanistan going back centuries. The non Pashtu speaking people of northern Afghanistan that is. They dont even class themselves as Afghans. This whole divide between Taliban from south and northern alliance is based on this historical rivalry over power in Afghanistan.
Now in your fascination, for the argument sake, you add pakhtoon population of Pakistan which is three times that of Afghanistan (there are more pakhtoons in Karachi then in kabul, where Karachi is not even part of Pakhtoon heartlands), these non pashtu speaking northern Afghans, who are already in minority against Pakhtoons in Afghanistan, will get absolutely crushed.
Afghanistan itself will get torn apart before any such attempt is even tried.
