My father told us that, when his civilian parents (his father was in the RFC flying SE5a) were killed in their beds by a V2 in October 1944, it was no trouble at all to go out on operations.
As with all history - it is written by the wiiner. What we need is less editing of the past, less clinging to the past. More of understanding everything, including their social and political attitudes at the time. We have the advantage of that hindsight and should remember it all, good and bad.
We need to look and acknowledge. Judgement is way past. Just think how many more wars there have been since then? Whatever historians and archiologists discover - there have always been civilian casualties. War is what humans do because we are tribal animals and every tribe/state/company/corporation thinks it is better and more deserving than any other.
