100 missiles from Iran is a statement: this is well within the capability of Israel to destroy with limited to no damage. But it is also nowhere near what Iran could launch in earnest. I really hope that everyone de-escalates. But I worry that Israel will escalate and then Iran will too.

I think it is unclear if Israel could defend from an all-out Iranian launch. I am sure both Iran and Israel know the answer (and maybe the US too). I really hope the rest of us never find out.
