@Mehru.. No they dont.. the reasons to stick together are more survivalist than anything else, they stick together because they fear being swamped over.
60 to 70% of Indians I know and have met personally will identify by their city.. compared to that.. only 20% pakistani's identify by the city.. the others want to know whether you are Pathan,Punjabi,Sindhi or Urdu-Speaking..(nobody asks about the baloch.. there just arent many of them to even think of including in this question). Now this would seem okay since you have only 4 cities with a few having multiple ethinic groups.. but the next question asked from.. lets say the Urdu speaking community is usually about the MQM.. or from a Pathan about the ANP.. not caring whether he or she even identifies with the party or not.. this is similar to what was done in tribal socities except on a larger scale.. and the concept then too was loyalty to tribe outweighs everything else...
Yes people do want peace.. the urban areas anyway and not because they feel its a necessity but because its what is "IN" with the civil activists and media..the rural sectors aren't too concerned with what happens regarding India.much bigger problems on their hands... , but there are large sections of society that wish for a holy war against India.. a section that has the potential to easily sway society.. this section has deep links within the Army..after all this section provided the man power for the fight in Kashmir and elsewhere...
anyway.. long story short..the Pakistani is fickle and easily manipulated..if tomorrow a party screams about injustice to their province regarding water it will register in their people.. tomorrow if the Media portrayed war with India as glorious and played nationalistic songs, Id be damned surprised if every one isn't boasting about their personal vendetta to fight the Indians or cheering the military whilst listening to eminem(except maybe Asma Jahangir and a few other women who may be spotted otherwise at gymkhana on Sundays).. and if tomorrow hypothetically.. Sindh wants out and the MQM is bought on board.. it would be very difficult to suppress something like that..
In a nation where law and order dont exist, justice is weak, infrastructure crumbling.. the military isnt going to hold it all together without an excuse.
I think there is a seperate topic for this discussion somewhere in the hundreds of threads about "India invents cloning" and "Are you keen on wearing ladies underpants"... so this can be continued there if you wish..lets not derail the flight of fancy here.
