Iran doesn't have to shoot down a single jet to win this war. Just move military hardware into caves. Sacrifice civilian infrastructure as the only viable bombing target. Wait it out until American domestic pressure from perceived war crimes ends the war. They can't afford to fight a land war or garrison over the entire country.

The fact that Israel has leveled much of the 140 square miles of gaza over the past 3 years and still fails to remove Hamas from power. No chance against 636,372 square miles and 93 million people. Worse odds than Vietnam. There isn't even a defined victory condition.

They are thinking on a longer timeline than a month. They kept some anti-air missiles in reserve for this phase of the war, where they aren't trying to defend Iran's airspace. They just need to hide and wait for opportunities to occasionally hurt the US, Israel and the other Gulf states.

Speculation.

1. Iran was retarded and didn't preemptively strike US staging who had local overmatch and first mover advantage. Nothing to do but weather hits, chip away at regional basing and wait until US+Israel operation tempo goes down. Can't sustain surge sorties forever, especially with regional logistics wrecked. US pilots tired now, on stims, making mistakes.

2. Iran not remain retarded, was hide and bide, waited for US to get complement, gathering data / building tactics to squeeze out surface-air without getting glassed. Regardless, Iranian capability seems much less degraded than claimed. Who knows how many of the 20k+ targets hit was basically just drawing down highend munition inventory, which now forces flying closer on lower end munitions.

At the end of the day, Iranian mosaic forces are chilling in underground bunkers waiting for US+co to make mistakes. Consider Iraq, a much smaller country by every metric ate 5x more sorties from more carriers and sustained regional air campaign and fell because they hedged on centralized IADs. Granted most Iranian hits are precision munitions (more efficient per sortie), but we simply should not expect Iran doctrine built on distributed survivability to be remotely defeated relative to effort expended.

Downvoters, care to explain?

Seriously, it's been sitting on this for entire month and now, all of a sudden, rolled out antiaircraft defense? What's going on?
