Funny to see another division added in the social strata. First it was how much non-indian one is what decided how much pakistani one is (persian, turkish, arabic, omani etc bloodlines), then it was the ethnicities punjabi, sindhi, bloody baluchi etal. Then it was about who is more islamic and now interestingly it is about who is more punjabi in pakistan. The bad news is this thinking. The good news is that at best next division could be based on town or village. Should not go further.
Regarding the zam zam, water has to be released when it is in excess in the reservior on the indian side. We cannot really manage your water lroblem for you. You need to spend less money on jamat ud dawa and more money kn hour water management. The state in lakistan worst effected otherwise will be punjab.
Imagine if india had not invested in dams then what would be the condition downstream in pakistan. Then they start complianing about indian dams too.
