I agree with you up to this point. Closer to the middle than what? The extremes? perhaps but perhaps not. Let's look at your questions. I don't see any reasonable criteria that suggests otherwise. Clearly it did. Since they didn't surrender after Hiroshima clearly dropping it on "the country side" would not have caused them to surrender. Dropping a second on the "country side" would have suggested that we didn't have the will to drop in on a real target. This was unknowable at the time as it is today but they didn't consider the risks worth it and I'd tend to agree. I object strenuously to the wording of this one. What "terror bombing" was carried out by the US? The target was military and industrial, they even dropped leaflets to war the Japanese people. Beyond that what do you mean by "different"? Again I think the answer is pretty clearly yes both from the view point of the time and looking back on it.
