A very important discussion. Until we do not base our identity on our land and its history (the history of our ancestors), we will remain astray. The day Pakistan begins seeing itself as a civilizational state like Persians, Chinese, Egyptians, etc., our rise would become a matter of time and a foregone conclusion. I have maintained at various fora that GOP's investment in the archeological department could be instrumental in constructing a national myth backed by evidence. As someone pointed out above, India cannot explain its origins without Pakistan. Today, the lands that we call Pakistan were the birthplace of the Vedic culture that was a synthesis of the migrating Central Asian Aryan and Indus inhabitants' belief systems. Vedas were compiled in our lands and from here moved Eastwards to the Gangetic plains. The first moves towards the subcontinent's cultural sophistication, in short, could be traced back to the lands of Indus. In antiquity, our land birthed the great Gandharan civilization.
So, Pakistan has to be begun to be perceived and marketed by fellow Pakistanis as the first successful nation-building project of Indus nations (all our major ethnicities) that has resulted in a super Indus state. A realization of the larger picture and a shared destiny would inculcate unity among our people and spark a drive to compete with the other world civilizations to rekindle the glory of ancient Indus and Gandhara.
