When said civilians are contributing to the enemys ability to wage war they are. And no it is not against ‘’Catholic principals ‘’ An evil so malignant such as Nazism and Japanese aggression had to be eliminated. . And it is utter nonsense to dismiss what Japans army did. Again, it’s quite easy to be self-righteous 65 years on. Do you suppose if Japan had such a weapon they would not have used it? Principles don’t mean anything if you lose and in war there no second-place for the runner up. Are you sorry America won WW2?
I am sorry, but I know what the Catholic principles are in this regard, and they do not make the distinctions you make.
I am very glad that America prevailed over Japan and Germany. The objective of the war was just. The methods — not always.
