Yes, I remember that, too.
Japan surrendered after two nukes. And also after the deaths of >2 million soldiers, sailors, airmen and marines. And also after the sinking of almost the entire IJN. And also after the burning of Tokyo, Nagoya, Yokohama, Osaka, and Kobe.
Bombing areas of Iraq and Syria controlled by ISIS cannot achieve the scale of military defeat inflicted on Japan by August 5, 1945.
Bombing could pretty well make it impossible for them to aggress further. Precision guided munitions can pretty well land in individual foxholes. In the desert, hiding places are hard to come by. Imagine Operation Arc Light in a desert environment...
I do think napalm should rejoin our active inventory though...along with cluster munitions. They just need to make sure the individual munitions all explode promptly.
