I think the regime narrative is mostly made up by Americans what's the difference between any of the Arab countries from Iran. The only difference is they are not controlled by America. It the same bullshit narrative of promoting democracy but in reality it's just about pushing for a government no matter how bad as long as it supports US control.
Iranians are not Arabs and thousands of them got gunned down earlier this year protesting the regime. "America bad" doesn't change the fact that the Iranian people deserve a better future.
