I'm not sure what point you are replying to; my reading of GP's (somewhat incoherent) post is that Iran has more in common with Nazi Germany than it does with (most) of western civilisation.

If we're working on a scale of 1-10 for "how close is a ruling government to Nazi Germany", Iran is maybe a 7 or 8.

The US, despite Trump's best efforts, is still only at a relatively benign 3 or 4.
