Well, I have no problem with Punjabis etc. because I think the policies of federal government effect the whole country. It does not matter who is in government. We can not live in islands within Pakistan and expect to develop.
Development comes in the whole country when it comes. It is not possible to develop just selected places.
What is important is the policies. And I am doubtful about Nawaz's ability to fight Taliban. Like I said, this is the graves threat to country today, not India. (India in the long run, Taliban in short term.)
