In addition, the study showed that there would be a considerable international outcry if the United States bombed the North, that this would seem a disproportionate response to what the North was doing in the South (which reflected a feeling that few Americans had, about how repugnant bombing was to the rest of the world, since much of it had been bombed, while America had done some of the bombing but had never been bombed itself), and that while this would not pose a serious problem if quick success was achieved, it would become sticky if the war became drawn out, as it was likely to be.
