The Iran situation only ended because America got involved.

Call me pessimistic but I don't think the "Iran situation" is anywhere close to being over.

Israel was running out of air defenses and couldn't establish air superiority over enough of Iran to stop Guerilla style launches

I don't think air superiority was ever in question. If anything Israel might be running low on anti-air defense that currently allows them to strike without receiving any meaningful retribution.

When talking about achieving air superiority it usually refers to being able to provide combined arms air support for ground troops.

If the US ended support, Israel would have no choice but to capitulate and stop being a genocidal apartheid always picking fights in the region, or to activate the Samson option.

Maybe if it happens right now.... but with trump in the White House I wouldn't count on it. I think another three and a half years of support maybe enough to where they could mobilize to a wartime economy and commit it's population to total war. Israel is currently trying to straddle a somewhat normal economy in the hopes they don't spook the civilian population into unrest. But who knows how crazy they're going to get in the next 3 years.
