The title is rather self-explaining enough. I'm simply curious about how much Pakistan can be realistically bigger and more successful as a state than how it has been IOTL. Also, about how would it effect its surroundings in particular and in the larger frame of geopolitics in general......
Also, IIRC IOTL there was a discussion of giving the crown of Pakistan(before it became a Republic) to the Emir of Afghanistan. IIRC, there was also a thread about that in this site as well. How realistic would that be to have happened ?
