alt Hacker NewsThe evidence we have is
* one early bomb is more or less equivilant to one conventional HE + incendiary raid.
* 2,000+ other bombs have since been detonated, a good number of which were orders of magnitudes more destructive than the early "first gen" bombs used on Japan.
Nuclear war with the larger weapons that followed would be considerably worse than incendiary bombs, in physical destruction, in immediate deaths, and in injuries and following mortalities.
It's all about scale. Not about the type weapons themselves. All the testifying of the horrors seems irrelevant.
Using nuclear weapons only tactically against counterforce targets would not be that horrifying.
