I don't think Iran will need to wait that long. This looks like the US/Israel are planning a joint operation counterattack on Iranian facilities. Which will trigger a retaliation in turn as Iran escalates in kind. Etc, etc.

The big difference now is that the US military will officially be getting its hands dirty in the region, much like we did in Desert Shield / Storm and in Libya. Very possible that the ghost of John McCain finally gets its long-sought-after bomb bomb Iran.
