Correct and a very dreadful scenario... I am seeing very anti-Punjabi and anti Pakistan propaganda coming from Pashtuns , baloch and sindhis. I don't know why Army is not doing enough on it...
This can be tackled in multiple layers but it has to start somewhere. I suggest 3 things.
1. Reverse 18th amendment and take education as federal domain. Design a national curriculum and put every child in school so that they can study proper history and not be brainwashed by hostile ideologies and fake ethnic supremacy. A national identity is only going to materialize if majority of Pakistan identify as Pakistanis first. The sole burden to carry national unity should not rest with Punjab and Army.
2. Ruthless covert and overt operation against terrorist. This include cyber domains , educational domains and physical domains. The agent of chaos are not just foot soldiers but people like nida kirmani , Raza rumi and etc
3. Use of high technology and surveillance in keeping a check on population. China is best in this.
Even if we adopt these methods , it will take decades before normalcy and desired results are achieved.

How is he responsible... As far as I remember, he killed a lot of baloch thugs.
