But your first source is a Saudi funded progranda channel claiming over 30k. You are war mongering, whether you like to admit it or not.
They don't claim to have "murdered" thousands, they claim under 3,000 civilians AND security personnel were killed, leaving 690 of the dead labeled as Israeli/US funded terrorists or armed instigators.
And the US/Israel has been openly talking about installing the son of last puppet removed in the last revolution, and the CIA has a reputation for doing exactly that, so it's not ridiculous.
You don't have to trust Iran, and I'm not defending the Iranian government, but stop bending backwards to accept the imperialist US narrative.
