Practice Relating to Rule 9. Definition of Civilian Objects
Sweden’s IHL Manual (1991) states:
Seen against the background of the enormous destruction of civilian property associated with the Second World War and all later conflicts, application of [Article 52 of the 1977 Additional Protocol I] could bring about an appreciable humanizing of warfare – people would no longer need to experience the catastrophe of bombed-out homes and ruined cities. However, Article 52 cannot be expected to bring about such great changes in warfare … [An] important reason [for this] is the lack of a definition of civilian objectives.
