Nevertheless, this does not justify the atom bombing of Nagasaki. I wouldn't know whether those who made the decision to bomb Nagasaki were interested in the Japanese Christians in that city.
Father, I doubt it entered their considerations (particularly for a secondary target.
However, there was a clar need (at least to their view, with which I tend to agree), to drop a second bomb.
We threatened them with a superweapon. We used it, and told them we would keep using it.
They didn't surrender (what had happened was beyond comprehension). To keep the threat, we had to keep going, and this was our only chance to come across as being able to do this repeatedly.
There was only enough refined material to make three bombs. We'd used one in New Mexico, another on Hiroshima, and only had one more for something like the next six months.
If the second bombing didn't bring about surrender, we were looking at a minimum of another six months.
