Yes I know what it was like then.
But what are the conditions like now? Are the cities habitable?
Now that my curiosity is up, I’m going to surf for a while & check it out.
The cities are habitable. There are “relics” of buildings but its a habitable zone. The bombs back then were airburst and released little fallout. Much of the Nagasaki blast was deflected because its a hilly area.
