Those cities were carried forward by building up the city around the monuments in a manner that the monuments don't become hurdles rather become places of tourist attraction and add to the overall aesthetics of the city, "by law construction is prohibited within 200 feet of historical sites and that's the bone of contention between the petitioners and government." the matter comes to life every now and then.
In Pakistan these places are first neglected, let to deteriorate, Qabza mafia allowed to takeover their lands and if not, it ultimately becomes dumping ground by the citizens for their garbage.
No sir, none here whether Pashtun party or Punjabi party wants Pakistan to not progress.
It's just a matter of difference of opinions, and opinions are formed following a long process that includes their experiences.
