So now that it has been seemingly verified that Nevatim Air Base suffered significant damage in the Iranian attacks, we can verify that Iran was serious.

If Iran can do this, it can basically neuter Israel attacking Lebanon, by getting rid of their air superiority. The only question is why not now? Because I think they are still afraid of the US.

On the Israeli side since they have admitted major damage, they almost have to attack so they can claim that they aren't threat from Iran.

But Iran has said if they attack back, they will also attack.
