Thanks for responding to the original questions.
I believe the "it's propaganda" response to your original post had much to do with characterizing Iran as a vile (did you say evil, too? Not sure.) country largely based on the way they wage war against Israel through proxy attacks on civilians.
By your definition, as I understand it, Israel is at least equally vile in its own campaign for decades against civilians in the illegally settled areas and occupied areas. The campaign in Gaza with still gets the fig leaf of the awful October 7 attack and is actually called a war by our news media. Gaza is being systematically leveled and it's people bombed, forced to live in the open, and starved.
Calling one side evil and guilty of bad things is indeed how Americans are roused for wars we have no business waging. Hitler is always invoked. The liberation of France is always invoked. We're liberators not invaders! Inside every Gook is an American trying to break out.
That was all used to roll us into Iraq which is one of the worst policy decisions of my memory.
A part of your reasoning was simplistic labeling. It reflects the odd American assumption that when we call somebody a Great Satan, we're invariably correct.
ETA: I see my slowness writing puts me in third place. Y'all had visual aids, too! Nicely done.
