In my opinion, this Iranian response was purely:
1. Performative kabuki for their domestic audience. They had to do something and make it look impressive. but come on. Half of what they launched was slow propellor driven stuff with a 9 hr flight time and they announced at launch.
2. Creates an awkward situation for the Saudis and other Muslims who have been improving relations with Israel. Create a wedge issue that forces them to pull back or anger their own street.
Seems to me it was mostly for show and measured to not really go for the throat. And carefully telegraphed to all parties especially the US.
Full scale war at the moment isn't really to Iran's advantage at the moment.
Israel has bigger fish to fry.
US has an election coming up and doesn't need to hassle.
My guess is everyone has gotten a shove in and proved their manliness. Everyone will put their joysticks back in their trousers move back to the normal level of tit-for-tat.
Of course, someone could get stupid.
