Playing devils advocate but if PIA pilots really are that bad why wasn’t the accreditation of the certifying authorities withdrawn long ago? What I mean is why didn’t this show up before in the accident statistics? Or were the Western aviation authorities turning a blind eye to it and their hands are now forced by this public revelation?

If civil engineers in a particular country were all fraudulent and buildings were collapsing that would surely be noticed. Or fraudulent surgeons and people dying.
