What strategic bombing does to a city is to produce, by military means, something similar to the massive urban destruction of last year’s earthquakes in Turkey and Syria: mangled pipes and wires, the ganglia of shorn rebars and masonry, homes cut in half, exposing their foundations like uprooted trees. Somehow there seems to be more debris than the total mass of the original buildings. Who could ever clear all this away, and where would it go? How would diggers sort the rubble from the bone?
