If Iran's AD / AA are completely offline, wouldn't it be game over for them already? Israel's jets could just simply fly around iran to scour for missile launchers/any potential targets
Range is an issue for both sides. Even with the collective EU and much of America’s tankers supporting them, the IAF cannot spend nearly enough time on station to even start putting together a campaign like that.
It’s quite clear that Iran was betrayed and sabotaged from the inside at the highest levels.
I would not be surprised if Iranian AD were given explicit orders not to engage or even power on in the initial phases of the Israeli sneak attack. And if there was that level of infiltration of the command echelon in Iran, the exact location of all of Iran’s AD systems were probably also sold to the Israelis to allow them to also perform a decapitation strike against Iranian AD. Hell, key Iranian AD assets may well have been ordered to predetermined positions out in the open to make it easier for the Israelis to do as much damage as possible in the opening attacks.
Iran is a deeply compromised society that is decades late in performing a deep and thorough purge of the traitors within. If they somehow survive this war, maybe they will finally find the backbone to do what is necessary to finally rid itself of the traitors within.
