I agree that the attitude is off-putting and the narrow view afforded to individuals is counterproductive.
There are, however, members of the intelligence community who have the breadth of view to make good judgment calls. Just not enough of them, and no accountability.
But isn't that what the Kissinger story was about? Getting the breadth of view, the knowledge, leads almost inevitably to (arguably) terrible arrogance about what you (the cleared) know vs what everyone else knows, and what you (the cleared) get to do about it.
