Iran is no longer a theocracy. To blame this on "The Mullahs," or worse, Iran's "Right-Wing" is to fundamentally misunderstand what is taking place there. This is a secular power grab done under the guise of Islam and revolution. The perpetrators are the enemies of western rapprochement, and the proponents of economic isolation. The Revolutionary Guards benefit from Iran's economic isolation, much like the mafia benefited from prohibition and other criminalized behavior. As any stereotypical movie gangster might say, "why ruin a good thing?"
I believe we are witnessing the disposal of Islamic pretense, and in fact a more honest and apparent Iranian police state. How that affects their place in the region and the world is still to be determined.
