I know people from different countries that also supported regime change, it doesn't mean they have a mythical insight we don't, it just means they don't understand the pattern.
Again, any Iranian who is aware of what happened to Iraq or Syria isn't cheering. You have to be extremely gullible to believe this time the US and Israel will liberate you, and extremely illiterate in how your own government works to believe killing a religious leader is enough to make it collapse. But let's say all Iranians in unison believed western propaganda: we still shouldn't be pretending it's a good thing they're being bombed. They're destroying HOSPITALS. SCHOOLS. ROADS.
Iranians can take over their own government in their own terms if you give them space to breathe. End all sanctions immediately and stop falling for imperialist propaganda.
