I think the Japanese realized - one plane, one bomb, one city. Also Nagasaki was where the torpedo’s used at Pearl Harbor were built. What goes around comes around. Karma is a bi**h.
Yes. The Nagasaki bomb exploded between the Mitsubishi steel & armament works and the Mitsubishi torpedo works, demolishing both. A picture of an unfinished torpedo sitting in it's cradle in the devastated factory, with the roof blown off, is not one of the more popular shots of the atomic bombings. I guess it's not kumbaya enough.
Hiroshima is the more popular narrative, as everyone plays the city out to be an innocent maiden. Hiroshima was actually an army garrison town and shipping port.
