I agree and that's my thesis.The A bomb deployment in Japan was possible because the entire free world knew the kind of casualties America was taking (all Allies took) in the Pacific - against a sneaky Asian enemy that had cold-cocked America. And as an island, Japan was isolated.
But that's simply a whole other question compared to civilian casualty for example at Holland, Denmark, France etc......After the war the US dropped A bombs in America ON THEIR OWN TROOPS (in the Nevada desert) (several times) ..... but THAT decision would have been easier than selling an A bomb solution on Germany to America's allies (and German-Americans in the USofA).
Plus the german chemical arsenal in conjunction with the V2(A4)!
Anyway that's only my personal opinion and we will never knew. But in contrast to Japan, germany had "something" dangerous to strike back and this was well aware to the allied intelligences.
