Obviously there are huge differences and it ushered in a new era of weaponry. What I want to point out is that atomic weapons were not an immediate step-change in destructive power. They’re actually not an exception to the greater point the author was making. The destruction caused by a single military operation was in the same league. The logistics were actually harder in some ways than traditional bombing. It would be months before the US would have more atomic weapons after the first two. So the one bomb versus hundreds doesn’t make a big difference when you have zero. This would all change dramatically over the coming years. But at the time of its first use, the atomic bomb was not as much of a leap forward in capability as you’d probably think.
