They are showing you the outcome.
In what you wrote you also made some conjectures as to what would the Japanese do had they won the war, but that has nothing to do with the issue.
America won the war. That is a good thing. To that end, America bombed a city full of civilians intentionally. That was immoral means to that moral end. Catholic theology is against employing immoral means to a moral end.
It is not complicated.
By the way, Our Lady is not a deity.
Madame, again, it’s not complicated. Had there been no Pearl Harbor, there would have been no Hiroshima and Nagasaki. And I disagree with you. The Catholic Church wasn’t doing the fighting, Americans were. You want to see ‘’outcome’’, then look at what Japan did. WHY do people you not look at that and only what America did? The bombings ended a war Japan started. Tough shit for them. It’s very easy to be so morally superior 65 years on, isn’t it? I’m a Catholic alright, but not a perfect one. Perhaps you fancy yourself that way? The war is over and no amount of second-guessing about the bombings is going to change the facts.
