But I am troubled now by some actions by NATO. including the socalled "collateral" damage we have wrought. and the embassy bombing. which I believe may undermine that sense of moral legitimacy. The embassy incident is only the latest of targeted errors which have caused civilian casualties. We have seen errant strikes on a refugee convoy. a civilian train. a bus and other incidents. While I understand clearly the difference between the brutal. deliberate and systematic attacks of Serb forces. which have resulted in the deaths of thousands and displacement of over a million more. and the accidental death of civilians caused by our wayward missiles. any serious moral reflection requires us to consider the impact of our actions on innocent civilians. Taken together.
