Actually, we are confused ideologically
Personally, I don’t see a problem with the head of the armed forces showing concern about the horrible economic situation of the country. A possible solution would be to stop curbing the huge military budget. Stop all their extravagant activities, messes, protocols, etc. to begin with. This affects the liberty with which the country can proceed to protect its security interests. And so the head of the armed forces, being a citizen of the country, and a very influential one at that is right in showing concern on something along these lines.
Bajwa is playing politics
Too late for him to wake up, only when his prime minister is ousted does he wake up. Yes, he’s right but this should apply at every level: even foreign policy. Historians repeat that aphorism because Pakistan’s military men have always enjoyed disproportionate political clout. The men in khaki have ruled directly for 33 of the country’s 67 years and have meddled heavily in politics the rest of the time, right up to the present day.
