Not so sure about Iran. I have looked for unambiguous quotes from them but can only find kooky religious stuff about Mahdism which is kind of like extremist Christians with their second coming madness.
Well educated Iranians seem to be Atheist whereas even intellectuals in Israel can be right wing religious nuts.
Certainly Iranian proxy groups like Hamas have unambiguously calked for a global caliphate
“Hamas, which is widely recognized as an Iranian proxy, has leaders and official rhetoric that go beyond the goal of liberating Palestine and at times explicitly reference the ambition of establishing a global Islamic caliphate.“
“On December 1, 2023, senior Hamas official Fathi Hammad declared on Al-Aqsa TV that the Palestinians are preparing to establish an Islamic caliphate with Jerusalem as its capital. He and other Hamas leaders have repeatedly stated that the liberation of Palestine is just a prelude to bringing all Islamic countries—and eventually the entire world—under Islamic rule, referencing the conquest of Rome and America as future goals”
For the record, my housemate of two years in Australia is Iranian. I also make music with an Iranian in Mashhad via the Internet (we jam electronic music). He is an extreme loner but tells me what society is like there.
Thanks, yeah someone else said similar here.
