As to the USAF in Bagdad you might want to read the report the Lancet put out today ( most of which is rubbish), collateral damage happens even with todays advanced technology.
From a military standpoint the bombing of civilian targets is counter productive as the Germans found out when they swithched bombing RAF bases in southern England to bomb London in 1940. Had they persevered the outcome of the Battle of Britain might have been quite different.
"It seems to me that the moment has come when the question of bombing of German cities simply for the sake of increasing the terror, should be reviewed. Otherwise we shall come into control of an utterly ruined land. We shall not, for instance, be able to get housing material out of Germany for our own needs because some temporary provision would have to be made for the Germans themselves. I feel the need for more precise concentration upon military objectives, such as oil and communications behind the immediate battle-zone, rather than on mere acts of terror and wanton destruction. "
