Every decade the Islamist regime has been in power, an uprising has cost it an element of its legitimacy.
As with the Soviet Union in its last days, the Islamic Republic can no longer appeal to its ideals; it relies only on its security services for survival. That is deadly for a theocracy, by definition an ideological construct. Ideological authoritarian states need a vision of the future by which their enforcers can condone their own violence. The theocracy’s vast patronage system will not cure this crisis of legitimacy. In many ways, Mr. Rouhani was the ruling clergy’s last gasp, a beguiling mullah who could enchant Westerners while offering Iranians some hope. That hope has vanished.
