I believe you might mean enriched uranium. Plutonium was also limited but used in FatMan on Nagasaki. Yes, this is true, but that was only a matter of time.
Is this "universal morality" time limited? Clearly the more moral point would be to demo the bomb. By definition. Inciniterating innocent children is not a moral decision, even if time is limited.
And I say this as someone whose father was on a troop ship for the SOuth Pacific right about that time and would have been in the horrific homeland invasion.
But we are talking morality here, not personal feelings.
ONLY if incinerating innocent children is considered moral.
Sounds like a made-up exemption. I thought we were talking universal morality here.
Wrong. The debate over "Just war" has been ongoing. It was never settled.
I'm an atheist. How can it bother me? I only point to it because it is technically part and parcel of Christianity and has been decreed by the faith to be integral (there was a heresy long ago settled that tried to pare out the OT from the NT. It was considered anathema. If you wish to talk religion please stick to the rules of said religion).
As such you are not allowed to simply dismiss the God of the OT because he makes you uncomfortable. (Although I AM curious what you think "universal morality" means if the author of said morality doesn't seem to follow such universal morals)
As an atheist I can point out the emperors clothing is missing.
