The neutrals can’t come to a deal with Imran Khan.
Free & Fair elections - This would mean a true representative of the public and more importantly a civilian who can’t be controlled by the establishment.
Accountability - No way either. If an honest person is at the helm how would the establishment blackmail him/her. More importantly, he will refuse to turn a blind eye on establishment’s corruption and its side dealings (NROx) with the politicians.
Institutions to operate within their constitutional limits - This would mean death to the establishment in current form. No doubling as foreign minister, election chief, health minister, finance minister, PEMRA etc etc.
So you see, the establishment’s interests are in direct conflict with the interests of Pakistan. If Imran Khan makes a deal with the establishment on these points, the Pakistanis will never forgive him.
