> This is what the regime says every time large protests erupt internally
Yes, but that doesn't mean they're not right. US and particularly Israel outright took credit for it, to a degree you'd be hard pressed to find any time in history. It wasn't just a spontaneous uprising, it was also very openly a foreign sponsored regime change operation.
Which doesn't mean they're aren't a lot of innocent people who have wanted to get rid of the theocrats all along getting murdered. I'm sure there are.
There are just enough in the opposition who have decided to ally with Israel (which would rather see Iran a Somalia-style failed state before a free and democratic Iran) and the dictator's sonthat any kind of moral legitimacy the movement could have had is out the window.
You were originally arguing that the Islamic Republic isn't evil because the protestors deserved to be killed because Israel and the US claimed to have coordinated the protests. I don't see how you're getting from "Israel and the US claimed to have coordinated the protests" to "therefore Iran's mass murder was legitimate". Even if the tens of thousands figure is exaggerated by an order of magnitude, it would still make the Islamic Republic an evil regime. Even if Iranians who criticize the regime are "batshit crazy", even if the US and Israel organized the protests, even if the Shah was really worse than the Islamic Republic, none of that justifies murdering unarmed protestors by the thousands. My position is that mass murder is wrong even if the protestors held opinions I disagreed with.
Also, if you know anything at all about the history of the Iranian regime, it’s entirely unsurprising that this happened. They respond murderously to every large scale protest, and have been mass murderers since they turned on the leftists and other allies who helped install them in ‘79.
> it's a foreign sponsored coup attempt
This is what the regime says every time large protests erupt internally. I’m not defending Israel, but these were innocent unarmed people protesting even if Israel played a role in organizing the protests. I detest the Israeli regime as well, but justifying either side’s mass murder is insane.
