I think Pakistan exists because its people suffered during its many occupations otherwise it would not have been a thought. Punjab and Sindh would have been India,KPK Afghanistan, Iran takes Baluchistan, Oman keeps Gwadar.
Arab invasion was brutal, Afghan invasion was brutal. I believe Pakistanis would have become monotheists naturally if theses invasions never happened. Since IVC we have been monotheists, its in our DNA and we have a more developed monotheism than others.
If I traveled back in time and witnessed Afghan warlords sitting on a throne in Lahore it would make me want to throw up. I don't view history like you do, Pakistani deaths are not part of the process like they are lemmings in the background for the great story of conquest for another civilization. You should be grateful WW2 happened and the British had to withdraw, they did an honorable thing in helping to legalize Pakistani borders and US beefing up its airforce. Polish man set up your ballistics for you, that's selfless. Not surprising it has never looked back since .
Afghanistan and India will balkanize by the end of this century and trust me on this Pakistan will remain intact. Fate loves irony
