The U.S. is full of anti-Iranian shitheads who are an existential threat to Iran. Of course you would defend Iran, where warranted, at least try to understand what they are doing, and why, because it is the reasonable thing to do. I think you could use some reading on Iran (
start here, for instance) to add a bit of color and nuance to your picture - because the black-and-white, us. v. them nonsense isn't really helpful.
I would guess you've followed recent reporting in the "imminent attacks" that were "prevented", and how these lies are falling apart already.
