We can offer a trade off. One hundred mosques incinerated for every forest fire reported this summer. Counting the fire bombings prior to August '45 plus Hiroshima and Nagasaki, that's a better deal than we gave the Japanese by a dozen cities and around 1,000,000 civilians.
You're not accounting for the HUGE increase in technology in the past 65-70 years. In terms of technology, your local Radio Shack is going to give today's saboteur a quantum improvement over what the best-equipped saboteur of the Axis Powers in WWII had. Not even mentioning that some of these people may have access to some military-grade stuff which takes it to an even higher level.
“The Japanese during WWII had the same idea and actually tried to accomplish it with incendiary balloons. I rate the old Imperial Military quite a bit higher in the competency department but they did not have the advantage of as many willing stooges and active collaborators on American soil as Al Qaeda.”
Of course they didn’t have as many willing stooges and collaborators, because Roosevelt locked them all up in camps! — Not that that’s a good idea, or anything.
