>Godzilla isn't a metaphor for the atomic bomb. He's a metaphor for Imperial Japan.
>With the original movie, Honda made the ultimate Take That! to Tojo and Hirohito by depicting Imperial Japan as an oppressive, rampaging Tyrannosaurus Rex (which, by the way, roughly means "Tyrant Lizard King" in Latin) that ends up leaving Japan in ruins, just as getting the country involved in World War II did. The Oxygen Destroyer is the real A-bomb metaphor. Its role in the story parallels the bomb's role in the War: it was a super-weapon built by a reclusive, self-loathing scientist to combat one threat (the rise of fascism) only to give rise to a worse threat (the Atomic age and the threat of nuclear annihilation). And just like Hirohito, Godzilla becomes much less menacing once the super-weapon leads to his defeat: after World War II, Hirohito went from a powerful dictator to a harmless figurehead in Japan's new democratic government. After the first Godzilla movie, the Big G went from the antagonist of a serious Horror movie to the protagonist of a series of Lighter and Softer escapist monster movies.
