I’m of the opinion that a crucial element of the pacification/rehabilitation of Japan after the war was the admission by the Emperor that he was just a person, not a god.
Proper subjugation of Islam requires (among other things) that Mecca and Medina be “nuked until they glow in the daylight”, to demonstrate that “Allah” has no power over the infidels and thus is a fraud.
Actually. that would have the opposite effect, as Islamic prophecy predicts the destruction of Mecca.
