I’m not offended by the outcome. Re-read what I wrote. I’m offend by what Japan is doing with this piece of a statue.
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.
