If a regime change will happen in Iran it will come from within. Over the last few years, the Iranian regime has been increasingly worried about a possible cultural change in Iran, fearing such a change might eventually destabilize the regime.
This is why the regime has been cracking down on every kind of artistic or cultural expression that is not deemed sufficiently Iranian and Islamic. Artists, filmmakers and actors, academics, intellectuals and authors – they are all suffering the heavy-handed oppression of the Iranian regime.
The regime seems to believe that the "soft war" is the true threat to its stability. Not a direct military attack, but rather a "quiet revolution" supported by the West. Therefore, it attempts to instill the "pure" Islamic values in the Iranian people (and to "export" these values abroad as well), while leading a never-ending campaign against anyone that is thought to be a propagator of a different culture.
The policies of cultural oppression are created by the Ministry of Culture and Islamic Guidance (MCIG) and the High Council for Cultural Revolution. Their goal is to put the values of Islamic culture – as defined by the founder of the Islamic Republic, Ayatollah Khomeini – into practice, and protect the Islamic Revolution from what they call the "cultural onslaught" on Iran.
