This is stupid take. They control foreign policy and security. While economy is taken care by with elected government. Its hybrid regime.
Here is a fact. Only PTI government have finally started working on cancer that is Pakistan economy after mismanagement for decades that result in IMF bailouts. You finally have exports increasing again after decade of stagnation. In same time frame rest of the world have leapfrogged you.
Still PTI is political party and Imran Khan have to win election, so you see recent fixing of petrol price no matter how expensive it becomes in international market.
Point is PPP/N had only 1 job, that to manage economy and they failed miserably.
