I wasn't thinking to question the validity of the Manhattan project, in the midst of a terrible war, and I don't think they really knew what they were creating. The still alive Hiroshima and Nagasaki survivors do pop up on TV here now and then, some feel compelled to go around and inform of the horrors of their experience, like it's there mission. It doesn't seem so much like bitterness they express, but a warning about what those bombs really are, if anyone has forgotten...or never learned.
Bigger bigger more powerful...the search for more damaging firecrackers never stops.
