The slogans must have unsettled the mullahs: “Death to Khamenei!” “Death to Rouhani!” “We will die to get our Iran back!” Imperialism has not revived the regime’s legitimacy, as the protesting Persians pointedly reject expending their meager resources on Arab wars: “Death to Hezbollah!” “No to Gaza, not Lebanon! Our life only for Iran!”
However the events on the streets unfold, their most immediate casualty will be the presidency of Hassan Rouhani and its false claim of pragmatic governance. In the aftermath of the Green Revolution of 2009, which rocked the foundations of the Islamic Republic, a sinister argument gradually pervaded Western salons and chancelleries. The convulsions of that summer, the claim went, were over no more than electoral irregularity. With the election of the so-called moderate Mr. Rouhani in 2013, the system rebalanced itself. Supreme Leader Ali Khamenei and his allies supposedly learned some hard lessons on the need to yield to popular mandates. Iranians want gradual change, we have been told, and believe that the system’s own constitutional provisions and plebiscites can be used to nudge it toward moderation.
Then, last week, Iranians took to the streets.
Every decade of the Islamist regime’s rule has seen one of its political factions lose its legitimacy through national uprisings. In the 1980s, the Islamic Republic waged a determined civil war against liberals and secularists who sought to redeem the revolution’s pledge of a democratic order. The student riots of 1999 ended the reformist interlude and Mohammad Khatami’s presidency, which had promised that the expansion of civil society and elections would harmonize faith and freedom. The reformists lingered as discredited enablers of a repressive regime, but no one believed in their promises of change from within. The hard-liners offered their own national compact, one that privileged economic justice over political emancipation. But the tumultuous presidency of Mahmoud Ahmadinejad produced only corruption and bellicosity.
Then came Mr. Rouhani and his centrist disciples with their pledge to revive the economy, primarily through foreign investment. Mr. Rouhani needed a nuclear agreement to lift debilitating sanctions and stimulate commerce. The Obama administration was happy to deliver, and Iran received tens of billions of dollars in financial dividends, including $1.7 billion in paper currency.
Instead of channeling that wealth into productive uses, Ayatollah Khamenei, the clerical establishment and the Islamic Revolutionary Guard Corps consumed much of it on foreign adventurism and corruption. Mr. Rouhani made a crucial mistake: overpromising and underdelivering on both economic and political reforms. His modest experiment in centrist rule has come crashing down, taking with it his injunction that all must trust the system. The regime is at an impasse. It has no more political actors—no establishment saviors—to offer its restless constituents.
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.
In the coming weeks, many in the commentariat will advise the Trump administration to remain silent and stay on the sidelines, as the Obama administration did in 2009. They will recommend that it is best to let the Iranian drama play itself out. If American officials weigh in, the argument goes, the regime would brand its detractors as agents of a foreign power.
Such stale prescriptions miss the point that Iranians are looking toward America to support their struggle. Democratic dissidents always do so. In that regard, Iranians are no different from non-Muslim dissidents from the former Soviet Union to communist China, who have struggled against tyranny and ardently welcomed American and European support.
Barack Obama has been rightly castigated for his silence during the Green Revolution. President Trump is right not to follow his predecessor’s discredited path. The White House should continue issuing condemnations daily, including through Persian-language media outlets, and follow up with sanctions targeting corruption and human-rights abuses. Congress should rediscover its once-bipartisan determination to hold the regime accountable for its crimes and push America’s European allies to overcome their mercantile greed and support Iranians striving to be free from theocracy.
The Islamic Republic is a relic of a century that yielded multiple ideological regimes claiming to have mastered the forces of history. By now most of them are history. Mr. Trump entered office with an understanding of the Islamic Republic’s profound threat to American security. The most consequential legacy of his presidency may be a Middle East free of its most powerful unsavory regime.
