Honestly it's more than that. Propaganda and lies put out by ALL actors in this conflict. If you want to understand what's going on I think you have the expose yourself to as many competing sources as you can find. And still you're going to end up with a very shoddy picture. The term for this is epistemic collapse.
One of the things I have disliked about the Iranian conflict is that their propaganda/messaging has been, by quite a margin, more reliable than what the US/Israel have been putting out.
I like to think that I live in a free/liberal democratic portion of the world, but seeing the "other side" being more honest really puts a dent in things.
Can you please expand on this with some examples?
