each instance where civilians were targeted:

from JMA
As far as targeting civilians is concerned Korea must surely be right up there?
as opposed to strategic sites being targeted with civilians being killed or wounded because of their proximity.

You could argue that WWII and Korea War targeting were determined using different constructs of military necessity and proportionality - as well as the factor of weapon systems inaccuracy (1940 ca. 20% within 5 miles of target; 1943 ca. 60% within 3 miles of target).

However, if there were instances of explicit civilian targeting, I'd like to see them because they would make good case studies for this thread.
