Those fighting In their mind believe the Punjabi/Sindhi army is trying to conquer them, destroy their tribal system, their culture, steal their resources, enslave them and the elite will then build big mansions, store wealth abroad, sell their souls to the west in order to stay in power. People often ignore the corruption takes place in Punjab/Sindh, the mafias operating, bribery, fake cases, murders, harming the weak. The people in power in any position be it local village leaders or the ruling elite are worse than baloch n kpk tribes. All the above is same as militant violence but noone talks about it because every house looks cleaner from the inside.
The 2 provinces of KPK and Balochistan are autonomous, they have the right for royalties, to protect their local traditions, the tribal areas have never been under the control of Pakistan army as they always been autonomous, this issue started when Pakistan sent their armed forces in those territory after 9 11, alot of tribes welcomed them but many didn't due to the threats, these same tribes who backed them were left alone when ttp militants slaughtered them. Think about this, how many years have Pakistanis tolerated military rule, after so long people had enough, Balochistan is under military and sardar rule for decades, with absolutely no accountability. Those who are oppressed will come back for revenge. Those who harmed the innocents must be hanged, then allow sincere negotiations with the tribal people, reach an agreement and move troops to the border. Remember if our security forces/police etc raid houses in Punjab at night, harassing women etc What do you think is happening in balochistan and kpk, the amount of lies, false cases etc. Accountability is a must, win the heart and minds of the people, work with the tribes. Lastly it's even more complicated than this, drug mafias are also involved, contract killers etc. Every powerful person is involved, when drugs come from Afghanistan, someone in Pakistan makes millions, from tribal areas to islamabad but no accountability.
