U.S. Government propaganda tries to give the impression that aerial bombardment achieves near-surgical accuracy, so that military targets can be destroyed with minimal effect on civilians. Technical documents give a different picture.
That's the whole point of good propaganda. You want to create a slogan that nobody's going to be against, and everybody's going to be for. Nobody knows what it means, because it doesn't mean anything.
There is massive propaganda for everyone to consume. Consumption is good for profits and consumption is good for the political establishment.
