If true, this is interesting:
The CIA is meant to spy upon foreign countries. The secrets we seek are located in foreign countries. Yet the bloated CIA bureaucracy exists almost entirely within the United States. CIA bureaucrats appear to find foreign service disagreeable. They enjoy their lifestyle and will fight with aggressive passivity to keep it that way. More than 90% of CIA employees spend their careers living and working entirely within the United States. . . .
The CIA has a military origin, and in the military, huge staffs are required for planning and logistics. There are relatively few actual fighting infantrymen – at the point of the spear – because to send that infantryman to combat requires support from tanks, artillery, aircraft and so on, which need massive expenditure and meticulous planning. The CIA has the massive expenditure and the huge staffs, but the CIA’s equivalent of the infantryman is the case officer, and the best case officers require only a passport and an airline ticket to get half a world away and produce.
