Compared to, say, the coverage from Ukraine during February 2022, actual information getting out from the ground is sparser. Or the opening "shock and awe" campaign in Iraq in 2003, there were Western and international media in Baghdad reporting on it in real time, shooting video from their hotels:

The reason why isn't really a mystery: Iran has never been exactly welcoming to Western media, and internet access there was intentionally shut off after the recent protests. There's plenty of coverage- it's front page everywhere- but a paucity of information.

It's all over social media, but hardly any of that is from Iranians in Iran, it's just people outside it like you and me mostly just yapping. Occasionally you'll hear something second-hand from someone with family in Iran who managed some brief connectivity.

They can't really not talk about it, it's a world war unfolding. It's going to affect every person alive. But as much as it can be, it is absolutely being mitigated in traditional media.
