"I can't say that either American film has done much in the way of social commentary. The 1998 film didn't even hint at any kind of social theme; it doesn't really take any discernible stance on anything. The 2014 film paid superficial lip service at best to the nuclear issue, but really there's almost nothing of substance there. Rather than offering caution about nuclear energy, the new film almost gives you the idea that nuclear weapons are actually the answer to everything. Despite the MUTO feeding off of radiation, owing their very existence to it, the humans decide using a nuclear blast is the way to go. And not only that, a nuclear blast in/near a major population center. And when that bomb actually detonates within a few miles of said population center, it's no big deal. No damage, no one is affected. And Godzilla himself is radioactive, the good guy, and not really a threat to people—he is linked to natural radiation. I guess it must be the good kind. So despite the throwaway dialogue about Hiroshima, it seems like radiation/nuclear weapons are not really a big deal to the makers of the film."
