It's strange how you're ignoring the fact that Israel attacked first. Iran retaliated, and did so after warning Israel of exactly what it was going to do so it could prepare. It did this even though Israel attacked Iran without a similar warning and assassinated an Iranian general.

Iran's response has been tepid and measured because it doesn't want to start WW3. Israel, on the other hand, very clearly does.

did you forget that irans attack came after israel attacked an iranian embassy unprovoked

No one is cheerleading but just like Israel can protect itself so can Iran, your feelings about their politics aside if you strike a sovereign nation you should absolutely expect a stroke in return if not scale war.

In response to their Embassy being bombed they launched a few outdated rockets and drones that they gave a week's warning of. Excuse me if I don't view that as legitimate threat.

I mean, I think the MAD situation between the USSR and the US had some success around mutual disarmament, no? Neither of them are devoid of nukes, now, but if I remember, the days of the world being nuked several times over in the event of ww3 is now long gone as a possibility. I dunno, this is obviously a pretty different situation, and that was kind of, not a fluke, but due to some pretty specific and complicated factors, I think. I dunno, I guess I'm just saying it's more of a matter of degree than kind of being such an all-or-nothing thing, which is how most people would perceive it.
