This will likely get very ugly indeed.
You'd have to think that the Mullahs (those who are left) would order everything ballistic to be unleashed on Israel.
Presumably that's what the ongoing strikes are targeting.
What would be the sequence?
Decapitate the leadership as you strike retaliatory sites, then hit the nuclear targets?
For a comparatively small air force - wonder how the IAF has done it - likely extensive use of that unknown drone they used in the last strikes.
