Iranians yearn for an Islamic Republic with food
Even so-called Westernized, fashionable, and tech-savvy millenials in Iran chant "Death to Israel."
And "Death to America." (And Britain.)
This may be exactly the problem. And the phenomenon is reflective of a great many young Russian and Chinese people too. They want all the material perks of American values, but still hold vengeful resentment towards America and long for the same imperial, global domination their prospective regimes espouse and nostalgize.
Iran is Persian not Arabic. Islam to them is an imperialist conquering religion. It is not native to Iran.
