Now that US President Donald Trump has refused to certify that the Joint Comprehensive Plan of Action (JCPOA) meets congressional requirements, much attention has been focused on the reverberations in Washington and within the Transatlantic alliance. No less important, however, are the emerging policy ramifications in Tehran. Contrary to assertions at home and conjecture abroad, Trump’s Iran policy may in the long run strengthen rather than weaken President Hassan Rouhani’s administration in several key ways.

First, Iranian stakeholders are now more united as a result of US threats, thereby solidifying the executive branch within Iran’s political system. Trump’s choice to decertify has reinforced the strategic vision offered by Rouhani and agreed to by Supreme Leader Ayatollah Ali Khamenei after the 2013 presidential election: to maintain unity on policy toward the United States, (nuclear) deal or no deal. This vision was predicated on eliminating the diplomatic and financial isolation that plagued Iran from 2005 to 2013. Whatever their differences, Khamenei needs Rouhani and his technocrats to repair the damage wrought by former President Mahmoud Ahmadinejad, and Rouhani needs Khamenei to provide political protection while he does so.

Since entering office four years ago, Rouhani has maintained arguably the most diverse and inclusive political coalition in the 38-year history of the Islamic Republic. The infighting will not subside anytime soon, but the survival instinct of most elites has kicked in, helping them recognize the need to deepen the middle ground that Rouhani has been cultivating. In nine months, the Trump administration has managed to spur a level of political unity and rally-around-the-flag nationalism not seen in Iran since the immediate aftermath of Iran’s 1979 Islamic Revolution and Iraqi dictator Saddam Hussein’s subsequent invasion.

Rouhani may also be strengthened because such unity has been a linchpin in the approach he has been advocating for the past 15 years and outlined in his 2011 memoir, “National Security and Nuclear Diplomacy.” In the book, he defends using that approach during his stewardship of Iran’s 2003-2005 nuclear negotiations with Europe because all decisions were made by consensus, with Khamenei’s endorsement. He criticizes subsequent negotiating teams for repeatedly miscalculating and abandoning his strategy of internal consensus-building and blames them for the polarization in Iran’s foreign and domestic politics that threaten to destabilize the country. Each of Rouhani’s criticisms have proven true — and Khamenei approved each of those mistakes, reinforcing Rouhani’s political standing.
