Pakistan does not have a reference point of its own. The Islamic system simply does not work, its dysfunctional. It like a square peg in a round hole. It is only ego that makes people persist with it. Look at Afghanistan, its not sustainable as a system.
No need to reinvent the wheel, pick the one that works and adopt it.
The reason why Pakistan was able to defend itself in the 50s and 60s is because the West helped to set up their army, the system works.
You have been western pet dog since early 50s. You are shamelessly trying to ape them, at least at the decision making level, both civil and military all along. What have you achieved?
The genius, that Jinnah was, even though not a very practising Muslim himself, he sussed it all out long ago when he said "Islamic socialism.. not other ISM". He was repugnant to the ideas of western model. The "square peg in round hole" you are talking about is actually the capture of state decision making by "westernised elites" who are dragging this country and its people at the whims of foreign overlords. If physical capture by proxies wasn't bad enough, now we have this phenomena of mental slavery.
