1. The protests weren't a wholesale denunciation of Iran's government. There was some who protested for that, but most protested because of the result of US sanctions resulting in a devastating degradation of Iranian people's quality of life.
2. The protests and their supporters were mostly in urban centers, which the US and Israel hit. Anti-government sentiment was annihilated the instant they were attacked (or became so low on anyone's priority that it's functionally the same).
3. US and Israeli bombs don't magically spare protesters ⁉️⁉️ Like, what could possibly go in your head when hearing that Iran is defending itself, to conclude that it's bad for Iranian people? The best thing for Iranian protesters is that Iran wins unequivocally

Your weak ass defense of the US would be ridiculous if Iraq didn't happen; the fact that you're unable to learn from it is sobering. Iraqis being freed was one of the reasons given back then; as a reminder more than a million Iraqis died to it.

Do you think Iraqi protesters were spared?
