Energy sectors, Metro projects and its expansion all over Pakistan, Military operation [that Imran Khan opposed], expansion of military operations all the way to Karachi, the stability of the economy in the shortest period of time.
Before 2013, Pakistan was different story, which at one time looked like dead end Iraq. Despite the corruption of PMLN, but the positive of PMLN has been noteworthy which made inroads for the future to give fighting chance. And that is all Pakistan needed, and hopefully, Caretaker government, leading by General Raheel, in charge with Technocrats, Economists, experienced Politicians, Generals can carry on to take Pakistan forwards to the modern century.
But as far as i am concerned about Imran Khan, it is same man who strong believed and insisted consistently throughout the history of Pakistan to maintain strong worded in favor of the peace treaty with Indian-funded Afghan-based Terrorist-outfit aka TTP over the military operation to eradicate terrorism that claimed more than 100,000 lives including children, and women all over Pakistan. So naturally, he can be blunt bitter sometimes.
His blunt 'pathechar' comment on PSL for the final match in Lahore is the prime example, and even at the expense of the betterment of Pakistan sometimes.
