The firebombings of Japanese cities didn’t have the “shock and awe” effect that the bombings of Hiroshima and Nagasaki did.
The Japanese were not moved so swiftly to surrender with the ongoing firebombing of Japanese cities. But the shock and awe of Hiroshima and Nagasaki moved them to surrender.
Sorry that the sarcasm of my initial posting wasn't more obvious to you. I was, essentially, employing an argumentum ad absurdum.
