you do realize that it is literally first time that so many ballistic missiles are shot together and nobody even knew till today if it's possible in general to defend against such attack ?

What do you think Iran shouldve done?

Stop supporting terrorist.

I dont see what that does to quell the domestic calls for a response to the embassy attack. Of course I want Iran to stop the bullshit, but the realty is that they couldnt let this attack go unless they wanted massive unrest. So the question remains, how should Iran respond to the embassy attack? To me this seems like just about that absolute minimum they couldve done.

there was no embassy attack. there was building next to consulate.

with regards to "domestic calls", you should go and read some data on support levels of iranian government, etc.
