I think soon Imran Khan will work out his differences with the military or PTI leadership will do it, they realised their mistake at under estimating them. Nawaz Sharif didnt learn from his mistakes though, everytime he came to power he had kickoff, even during his 2013 term, he had kickoff with General Raheel Sharif, Dawn Leaks, Geo attacks if you remember, he even went after General Mushraff. To be fair with PTI and Imran Khan, they claim they want reforms, help the people of Pakistan, development, education etc, how can they do this when fighting with the opposition and the military, its not sustainable. They need to understand on the international relations its a similar path, Pakistan cannot talk about development, trade, economy growth if we plan to fight the world, it will not work. They must reflect and learn, play good politics and win back power.

By the way Imran Khan and PTI were anti Fazlur Rehman and Mahmud Khan Achakzai, both were labelled with many different names, Fazlur Rehman was also President of PDM who toppled PTI government but today both are close allies so this shows even Imran Khan and PTI will change when benefits are given.
