Unfortunately this is more interesting than a failed Diego Garcia attack — the late Ayatollah had a self-imposed range limit on the strikes or tests they would carry out. By using IRBMs in this fashion, it’s clear the new regime no longer feels bound by that restriction..

Which is notable since it’s about the same distance from Southern Iran to Diego Garcia (3,800km) as it is from Northern Iran to London.

They had a religious ruling on the range, and they also had a religious ruling on "not creating an atomic bomb."

The question of whether the world can assume its security on some religious rulings of some Ayatollas is still standing, as these rulings can apparently be changed or bypassed.
