Taking on Tehran
The United States has withdrawn from the 2015 nuclear deal (the Joint Comprehensive Plan of Action, or JCPOA), designated an arm of Iran’s military (the Islamic Revolutionary Guard Corps) as a foreign terrorist organisation, imposed economic sanctions against nearly one thousand individuals and entities and taken steps to make it extremely difficult for Iran to sell its oil.
U.S. policy is working, in the sense that most countries (including those that disagree with Trump’s policy) have judged it better to maintain trade and investment ties with the U.S. than with Iran. Iran’s oil exports are down sharply and its economic isolation is real and growing.
The economy contracted some 4% in 2018 and is projected to shrink as much as another 6% this year. The currency is plummeting. There are reports of price spikes, shortages of food and medicine, and reduced financial transfers to Hezbollah and various militias central to Iran’s attempts to exert influence around the region.
What is driving the U.S. administration?
But if the pressure is clear, its purpose is not. Many in the Trump administration appear to favour regime change. But this is unlikely to happen. Forty years after the revolution that ousted the Shah, Iran’s unique political-religious system and government appears strong enough to withstand U.S. pressure and to ride out the economic difficulties.
A more likely outcome is that U.S. economic warfare will lead to actual warfare. Iran has made it clear that it will not just absorb pain; it will mete it out as well. Iran was almost certainly involved in recent attacks on oil tankers in the Gulf of Oman and drone strikes on a Saudi airport launched by Yemen’s Houthis.
Iran’s government also has announced its intention to break out gradually from the nuclear constraints imposed by the JCPOA. According to the International Atomic Energy Agency, Iran is slowly increasing its production of nuclear fuel. The country also appears determined to bring the level of its uranium enrichment closer to weapons grade.
All this raises the risk of a costly conflict between Iran and one or more of its neighbours or the United States. Such a conflict would almost certainly escalate and spread, leaving the U.S., Israel and Iran worse off.
