So, if you want your argument stronger: 7k deaths confirmed, 6400 protesters, 200 regime officers, and 400 bystanders.
Plus 11k unconfirmed dead, according to HRANA, so at most 18k dead during the Iranian protests. They also jailed 50k people, and before the war, it seemed a third of those were destined to be executed if the trend continued.
Iran also execute between 50 and 500 people a year, every year, and in the last 5, it was closer to 500, culminating in 2025 where 1500 person got the death penalty.
A regime that has to kill that much is weak, and would probably have fallen on itself if the US hadn't launched any strikes.
