Note how modern everything looks, and also note how the women are dressed. Obviously, things have regressed in Iran since then. But why?
I’m sure will argue that the current theocracy is responsible for the problems facing Iran, but this view is somewhat shot-sighted, and begs the question of why a prosperous country put this government in charge. Part of the answer to that question is, unsurprisingly, US intervention in foreign affairs. Wikipedia has a pretty good overview of the matter, so I will simply say that the US government’s attempt at meddling in another nation’s affairs set up the chain of events the established a literally retarding government. No wonder Iran hates the US.
