It's authoritarian, certainly. Totalitarian, in definition, yes, but in the 1980s more so. There is now a different approach, although the ideology is totalitarian and remains totalitarian. That is why the Iranian leadership is sensitive about your getting information about where the society doesn't agree with the leadership.
The effort and the tendency is to give you a monolithic view of what Iranians want, that Iranians want nuclear power, and that Iranians are belligerent and understand their government's foreign policy. The truth is that Iranians have no say in the government's foreign policy and that Iranians have repeatedly expressed concern about the government's use of violence outside Iran.
Even nuclear power or nuclear energy is debated. The Office for Consolidation of Unity, the umbrella group for student associations, put out a statement saying they were very concerned about the nuclear ambitions of the government, which attract too much hostility outside Iran and are not worth it or not good for Iran's national interests. But these statements never get visibility, because the government doesn't want them to get visibility.
So one thing you could do is to give visibility to the voiceless.
