Seems to me the arrogance of inside or outside the system has been institutionalized especially in the military bueracracy. Seems another ex military writer the late Col. David Hackworth wrote about this in at least 2 of his works About Face and Hazardous Duty. In his examples it wasn't just intelligence, but training and procurement policies suffered the same arrogant thinking. Col North has exposed this type of thinking with the intelligence issue. Unfortunately this practice has been around to some degree since the 50s when Eisenhower warned of the military industrial complex that was growing at the time of his departure from the WH.
