Nope. You are wrong...Here are some facts...
St. Mary's Cathedral was one of the landmarks that the Bock's Car bombardier had been briefed on, and, looking through his bomb site over Nagasaki that day, he identified the cathedral, ordered the drop, and, at 11:02 am, Nagasaki Christianity was carbonized, then vaporized, in a scorching, radioactive fireball. And so the persecuted, vibrant, faithful center of Japanese Christianity became ground zero, and what Japanese Imperialism couldn't do in 200 years of persecution, American Christians did in 9 seconds; the entire worshipping community of Nagasaki was wiped out.
You need to provide the source of your "facts" including the source where Kermit Beahan is quoted as saying he used the Urakami Cathedral as his aimpoint. You know very little of the conditions that existed over Kokura and Nagasaki on 9 August 1945.
I suggest you read the following, which was written by the Roman Catholic pilot of Bockscar, Charles W. Sweeney.
To believe that Sweeney and his crew deliberately failed to bomb Kokura, the primary target, after making an unprecedented three passes over the city in search of their aim point, thus placing themselves, their aircraft and their mission in great peril and instead fly off to make a single pass over Nagasaki which was under overcast skies and smoke, and specifically target the Urakami Cathedral for destruction is absurd.
the entire worshipping community of Nagasaki was wiped out.
Another false statement. ~5,000 Catholics alone survived the bombing. Bearing false witness is a mortal sin. You revisionists are fools.
