I dont think that way actually. Simply because ACM Rao was never the "deserving" candidate for this post. He was the MOST junior out of 5 Air Marshals. And he was chosen by President of Pakistan NOT because he THOUGHT he was the best or because of his competency but because of an issue which i dont think i should disclose here.
Air Marshal Shahid Latif was delvered with sweets by all his relatives and blue tapers since every senior officer took Air Marshal Shahid Latif as the sure shot for the next ACM days before the announcment of the winner. It was highly speculated that he will be next Chief of Air Staff simply because of his mind blowing record and seniority in the PAF.
After the appointment of ACM Rao, Air Marshal Shahid Latif gave his resignition papers to the President but they were not accepted. Further more, ACM Rao AGAIN appointed the RETIRING VICE CHIEF OF AIR STAFF at the AHQ to assist him in command and control of the PAF since he had no regular experience in commanding a force of more then 700 jets and over 65,000 personnel.
TIDBIT:
ACM Rao's BROTHER is a MNA in National Assembly!
