It is very credible because a few days before this happened, Israel wiped out Iran's air defense systems with f35 attacks.
Or, you know, a theocratic autocracy that realizes the perception of its military power is critical to keeping the populace in line?
And admitting to an inability to stop military action on one of their most heavily defended targets by the very enemy they've whipped their supporters into a froth over is a bad look?
I think the U.S. whipped the Iranian government's supporters into line by treacherously using peace negotiations as a pretext to target their scientists, helping Israel launch a completely unjustified sneak attack with all the Mossad rats they had hidden in the country, and facilitating the genocide in Gaza. With enemies like that the Iranian government hardly needs help.
I'm not sure how that disagrees with my point.
