The Washington Post | Kambiz Foroohar: For a decade, the U.S. and other major powers squeezed�Iran�s economy to force it to rein in its nuclear program. That ended in early 2016, creating an opportunity for Iran to bounce back. By many measures, it has. Notably, its oil production exceeds�pre-sanction levels. Still, Iran hasn�t reaped as large a dividend as many citizens expected when the country agreed in 2015 to limit its nuclear program and subject it to external inspections. One obstacle has been U.S. sanctions that remained even after every world power lifted its nuclear-related ones. And under President Donald Trump, who opposes the accord, the U.S. keeps pulling the noose around Iran tighter. At stake is more than Iran�s gross domestic product. Its prosperity affects the role the country plays in the world�s most volatile region.

The Situation

Prospects for Iran�s economy grew cloudier in October, after Trump refused to certify to the U.S. Congress that continuing to waive nuclear-related sanctions on the country serves U.S. interests. That opened the possibility that Congress would restore those sanctions and so added to uncertainties about investing in Iran. Already, U.S. sanctions on financial transactions with Iran have made international companies wary of doing business there. Some overseas oil and construction companies as well as airplane and car manufacturers like Airbus Group SE and PSA Peugeot Citroen have�inked deals,�but not to the extent projected by President Hassan Rouhani, a moderate and champion of the nuclear accord who has courted foreign investors. Iranian officials say that in 2017, visits by trade delegations have slowed and larger companies are holding back on making commitments. Most American companies have been kept on the sidelines�by a sweeping 1995 U.S.�ban on trade and investment, triggered�by concern about Iran�s links to terrorism. Since�the nuclear deal, Iran�s economy has risen out of recession, but almost all the growth has been in the oil industry.�For other businesses, lack of access to finance has been a major impediment. Iran�s May presidential campaign featured voter complaints that benefits of the nuclear deal had not filtered down to ordinary citizens. Still, Rouhani was re-elected, beating back a challenge by hardliners inclined to embrace rather than dodge confrontation with the increasingly hostile U.S. Since Trump became president in January, the U.S. has imposed new sanctions related to Iran�s�ballistic missile program�and its premier security force, the Revolutionary Guards Corps, neither of which are covered by the nuclear accord.

The Background

The Pahlavi monarchy that ruled Iran from 1925 transformed a small agrarian economy into a booming one, developing�both manufacturing and oil production. Industrialization and an influx of rural Iranians into the cities led to cultural tensions that were among the factors that provoked the 1979 revolution. Subsequent leaders have never quite settled on the appropriate shape of the economy in an Islamic state. At first, much of the economy was nationalized. Starting in the late 1990s, the country�s leaders tried privatization.�Many assets, however, ended up either with the Revolutionary Guards, Iran�s premier security corps and the most powerful economic actor in the country, or with its affiliated corporations or religious charities. Elected in 2005, President Mahmoud Ahmadinejad took a populist turn, expanding credit, spending freely and handing out $15 a month in cash to every citizen. These policies fueled inflation just as sanctions began to bite. Rouhani was first�elected�in 2013 promising to end Iran�s economic isolation.

The Argument

Should the rest of the world want Iran�s economic revival to succeed? Some in the U.S. and Europe think that supporting Iran�s economy � about the size of Austria�s � is the�best way�to boost political moderates represented by Rouhani. They say that better integrating Iran into the global economy creates incentives for the country to abide by the nuclear agreement and other international norms. Skeptics argue that such thinking underestimates the commitment of Iran�s leaders to expanding their power in the region.
