But from the end of WWW2 or so I agree
I wouldn't agree considering one of the largest aerial bombing campaigns ever mounted was during Operation Menu in the late 1960s and early 1970s, where over 2.5 million tonnes of high explosive bombs were dropped on countries that had virtually no air defenses. The tonnage dropped was many many times that dropped during the second world war.
Shock and Awe was only a few years ago.
