non-punjab parties would love to see Punjab being divided but will not let Sindh, Balochistan or KPK be divided into 2 or 3 units.
socioeconomic condition in South Punjab is far better than North western Sindh or even eastern districts of Sindh. Besides Karachi Sindh should be divided into upper and lower Sindh, which wont happen as both PPP and Jiye Sindh etc will join hands against it.
Balochistan became current balochistan after we bought makran coast from Oman. There needs to be a makran provinve, kohlu/Sibi, Loralai and Balochistan province but that would just fuel BLA and Other separatist and even antagonise the 18th century mindset sardars who believe themselves to be the new Anunakis or a superior race.
Lastly, south KPK is as backwards as most Sindh, south Punjab and Balochistan.
The fear is that once south Punjab is created, the next division will only happen after another 50/70 years.
Hafiz sb, bcoz of his iron grip and whip, is probably in the best position to do this and ride the storm as well. The so called democratic parties have their vested interest to maintain the status quo.
