I think that the use of those bombs in Japan to some degree kept them from being used in other wars (there was push for their use in Korea, even Rep. Lloyd Bentsen advocated their use and encouraged Americans to contact their congress critters about supporting this measure).
We could have even had a few launched our way from Cuba, after all, until someone touches the hot stove, someone is always going to want try it.
Mr. Bentsen knew a little bit about atomic warfare.
