“Maximum pressure” harms diplomacy and increases risks of war with Iran

Daniel DePetris

November 19, 2021

Key points

  1. With an economy less than a third the size of the U.S. defense budget and a military ill-suited for offensive operations, Iran is at best a minor threat to the U.S., and one in a region of limited strategic importance. The U.S. need not obsess over Iran policy.

  2. While Iran does not threaten vital U.S. interests, U.S. policy does seek to moderate Iran’s behavior and restrict its nuclear weapons development. That is why the U.S. negotiated the JCPOA, an agreement with Iran, Europe’s major powers, Russia, and China to constrain Iran’s nuclear activities.

  3. The Trump administration abrogated the JCPOA and imposed a policy of “maximum pressure” designed to compel Iran to renegotiate on nuclear issues and moderate its foreign policy. Rather than capitulate to U.S. demands, Iran expanded its nuclear program and increased its aggression in the Middle East.

  4. U.S. withdrawal from the JCPOA and imposition of a maximum pressure strategy harmed diplomatic efforts with Iran and increased the prospects of direct conflict.

  5. The Biden administration has so far continued the policy it inherited from the Trump administration. With nuclear negotiations between the U.S. and Iran predictably stalled, U.S. officials should abandon maximum pressure.

  6. Ongoing diplomacy is the best path to revive the JCPOA, and more importantly, lower the risks of war. Even if the JCPOA dissolves completely, U.S.-Iran diplomacy, including on nuclear issues, should continue. War with Iran is not worth the costs.

 

Assessing the current state of nuclear talks

On May 8, 2018, President Donald Trump announced the United States would withdraw from the Joint Comprehensive Plan of Action (JCPOA, or Iran nuclear deal). In its place, President Trump reimposed economic sanctions the United States previously committed to lift as part the agreement, and his administration pursued a “maximum pressure” campaign with two goals: (1) to force Iran to renegotiate an agreement on its nuclear program to remove its path to a bomb and (2) to pacify Iran’s foreign policy.1 That policy failed, yet it continues today. Tehran responded to approximately one year of U.S. pressure by escalating its malign behavior in the region and ceasing its obligations to restrict nuclear activities established under the JCPOA. Upon entering office, President Joe Biden committed to negotiating a mutual return of both parties to the deal. Returning to the JCPOA would be a first step to what Secretary of State Antony Blinken called “a longer and stronger agreement.”2

After months of communication between U.S. and Iranian officials, indirect talks began in April 2021.3 In Vienna, the United States and Iran (with assistance from Germany, France, the United Kingdom, the European Union, Russia, and China) exchanged proposals and stated their expectations for how the negotiations should proceed. The parties established working groups to determine which sanctions the United States must remove and which nuclear concessions Iran must make for both sides to resume compliance with the JCPOA.4

Hindering talks is the issue of synchronization: how and in what order each side will meet its obligations committed to in the JCPOA.5 Washington insists on a concession-for-concession framework whereby both sides return to compliance simultaneously, while Tehran demands the United States lift sanctions before it rolls back its nuclear activities in breach.6 The inauguration in August of Iran’s new president, Ebrahim Raisi, a hardliner and disciple of Supreme Leader Ayatollah Ali Khamenei, added to the difficulty.7

Iran questions the United States’ ability to uphold a resumed agreement since it abrogated the original deal even though Iran was meeting its commitments. Even as Iran’s top nuclear negotiator, Ali Bagheri Kani, says talks will resume on November 29, the Raisi administration insists the United States guarantee it will not withdraw again (including under a future U.S. administration).8 After talks paused in June, Iran started up more advanced centrifuges and enriched more uranium at higher quality.

U.S. officials accuse Iran of stalling. Secretary Blinken warned in October the United States and Iran could reach a point when coming back into compliance with the JCPOA is no longer viable.9 The Biden administration is reviewing more punitive options, including new sanctions on networks transporting Iranian crude oil to China, Iran’s largest customer.10 Proponents of the ongoing escalation strategy advocate for legislation that triggers additional U.S. sanctions if Iran does not fulfill its part of the nuclear agreement by a specified date.11

 

Iran’s enriched uranium stockpile

The JCPOA limited Iran’s enriched uranium stockpile to 202.8 kg, which Tehran began exceeding in 2019, one year after the U.S. withdrew from the agreement.

 

Iran’s position hardened because of pressure

President Trump’s decision to pull the United States out of the JCPOA and reimpose comprehensive economic sanctions on Iran is directly responsible for the current dilemma.12 As explained in May 2018 by the then Secretary of State Mike Pompeo, the additional pressure aimed to force Tehran into a new set of negotiations about Iran’s conduct, of which its nuclear program was only a part. Secretary Pompeo listed 12 demands Iran must meet for the United States to lift sanctions: The Trump administration expected Iran to make a full account to the International Atomic Energy Agency (IAEA) on its prior nuclear work going back decades, stop all uranium enrichment, terminate its ballistic missile work, end support to its proxies in the Middle East, and withdraw Iranian forces from Syria, among other requirements. Until Iran’s government met those demands, sanctions on its economy would continue and, if necessary, accelerate.13

According to the architects of this escalation policy, financial distress on Iran’s economy would become so great that Iran would have no choice but to resume talks with the United States in a far weaker position.14 Thus, the more strained Iran’s fiscal situation became, the more likely Iran’s leaders would offer deeper concessions on its nuclear program and its overall foreign policy. President Trump’s National Security Advisor John Bolton also argued economic sanctions could help promote regime change in Tehran.15

This escalation policy misunderstands how states tend to respond to pressure. As John J. Mearsheimer of the University of Chicago has written, foreign pressure rarely compels states to surrender their core security interests—particularly when the state in question is weak and shares a neighborhood with committed adversaries.16 Iran is not exceptional. Iranian officials operate in a political system that, like many others, rewards policymakers and politicians for their nationalistic bona fides and discourages them from conceding to foreign pressure—particularly from the United States. Acceding to U.S. demands would expose Tehran to more exorbitant demands in the future.17

The maximum pressure escalation strategy ignores this reality. Though sanctions harm Iran’s economy, it has not and is unlikely to result in the stated political outcomes sought by the policy.

Between 2018 and 2020, the United States enacted broad sanctions on Iranian sectors ranging from automobiles and metals to construction, mining, manufacturing, and textiles.18 In 2020 alone, Iranian-linked entities and individuals comprised more than 40 percent of the Trump administration’s total sanctions designations.19 Secondary U.S. sanctions on Iran’s energy sector, which penalize third-party nationals who import, finance, or transport Iranian crude oil and natural gas, diminished Tehran’s export capacity. The Trump administration’s cancellation of Iranian oil waivers to China, India, South Korea, and Japan in 2019 took hundreds of thousands of barrels of Iranian crude offline.20 Iran’s total crude exports decreased from 2.5 million BPD in 2017 to 400,000 BPD at the end of 2020—an 84 percent reduction.21

 

Timeline of maximum pressure strategy

The pressure strategy begun by President Trump and carried forward by President Biden increased confrontation between the U.S. and Iran beyond Tehran’s nuclear program.

 

Predictably, Iran countered U.S. pressure tactics with pressure of its own. Because other countries could no longer trade with or invest in Iran, Tehran had less incentive to comply with uranium enrichment caps and restrictions on centrifuge development. In May 2019, a year after the United States left the JCPOA, Iran announced it would “reduce compliance” with some provisions of the deal.22 In July 2019, Iran breached the JCPOA by surpassing the ceiling on the amount of low enriched uranium it could stockpile under the deal.23 Two months later, the Iranian government announced it would forgo limits on nuclear research and use an array of advanced centrifuges, including multiple IR-6s, which enrich uranium 10 times faster than the IR-1 type allowed under the JCPOA.24 On January 4, 2021, Iran resumed enriching uranium to 20 percent, another abrogation of the nuclear agreement.25 By April, Iran began enriching to 60 percent. As the IAEA assessed in a recent report, Iran’s enriched uranium stockpile exceeds 2,440 kg, more than 10 times what the JCPOA permits.26 In recent weeks, Iranian officials said the heavy water reactor in Arak, the construction of which was halted under the JCPOA, may soon forge ahead to completion. If finished, it would give Iran a plutonium pathway to a nuclear bomb. Iran is much closer to a nuclear bomb today than it was before the United States withdrew from the JCPOA.27

The current policy’s record of failure extends to non-nuclear issues. Since the United States pursued this escalation strategy, Tehran grew more belligerent in its regional foreign policy. Unable to market its oil to foreign buyers, Iran attempted to limit its neighbors’ export capacity. Iran’s Islamic Revolutionary Guard Corps (IRGC) attacked and damaged civilian tankers and cargo ships in the Persian Gulf. In May 2019, a month after the United States terminated waivers for Iran’s top crude buyers and designated the IRGC a Foreign Terrorist Organization (FTO), mines likely placed by Iran damaged four oil vessels.28 A month later, U.S. Navy investigators held Iran responsible for mine attacks on two Japanese oil tankers in the Strait of Hormuz.29 The IRGC seized another three oil tankers (one British, one Liberian, and one Iraqi) in July and August 2019.30 And in September of the same year, Iran attacked Saudi Arabia's Abqaiq facility with cruise missiles and drones, interrupting about half of Saudi oil production for several days.31

Pressure also has a military dimension. Approximately 20,000 additional U.S. troops were deployed to the Middle East between May 2019 and January 2020, bringing the total U.S. military presence in the region to more than 80,000.32 In May 2019, the Trump administration ordered the deployment of a carrier strike group, complete with a detachment of B-52 bombers.33 Yet a larger presence meant greater risk of Iranian or Iranian-linked retaliation.34 Shia militias in Iraq and Syria, the most powerful of which receive financing from Iran, fired rockets at U.S. military sites in both countries. Defense Intelligence Agency reports assess Iranian-backed militias in Iraq attacked U.S. targets more than 300 times between late 2019 (when U.S. sanctions were beginning to have full effect on Iran’s economy) and April 2021.35 Some of those attacks killed Americans and prompted U.S. military retaliation—a cycle of escalation that reached a pinnacle on January 3, 2021, when a U.S. drone killed IRGC Gen. Qassem Soleimani, head of Iran’s Quds force, outside the Baghdad airport. Iran struck two U.S. bases in Iraq with ballistic missiles days later, leaving more than 100 U.S. military personnel suffering from traumatic brain injuries.36

The strategy is causing problems beyond the Middle East as well. Seeking to preserve economic ties with Iran, Europe created a euro-denominated payment system (INSTEX) to get around U.S. sanctions. European countries and Iran completed a first deal of medical goods on the financial channel in March 2020, but nothing of note since. Despite INSTEX failing to take off, Europe’s challenge to the U.S.-led financial system offers other countries a precedent to undermine the power of U.S. sanctions and the U.S. dollar as the world’s reserve currency.37

 

Do not double down on a failed strategy

Biden administration officials acknowledge the ongoing pressure strategy is counterproductive to U.S. goals in the Middle East and beyond. In October 2019, Jake Sullivan and William Burns, now President Biden’s national security advisor and CIA director, respectively, wrote the United States leaving the JCPOA and instituting secondary sanctions on Iran failed to push Iran into softening its negotiating position.38 Earlier this year, Robert Malley, U.S. special envoy to the Iran negotiations, said the pressure campaign “failed miserably and hurt U.S. interests.”39

Despite rhetoric of departure from the Trump administration, the Biden administration continues the same pressure strategy. The Biden administration is so far unwilling to spend political capital to abandon the failed policy. But the politics would be worse if the United States and Iran stumbled into a pointless, costly war. Current U.S. policy increases this risk. The United States stations tens of thousands of troops in the Middle East (mostly on large bases in the Persian Gulf, susceptible to Iranian ballistic and cruise missiles) and conducts frequent navigational patrols which produce tense encounters with Iranian naval forces.40 Shia militias funded and influenced by Iran continue to attack the approximately 3,500 U.S. troops deployed in Iraq and Syria with drones and rockets—as recently as October 20, five drones armed with explosives targeted the small U.S. outpost in Syria’s Al-Tanf.41 The status quo increases the probability of a clash that escalates into a more violent conflagration.

The United States faces two choices: (1) continue to enforce the same strategy that makes negotiations more difficult and risks war or (2) unwind this failed policy, create space to advance diplomacy, and avoid a needless war. The United States risks nothing by first removing some pressure—doing so would provide domestic political cover for Iran to resume compliance, and any failure on its part could be easily undone by reimposing some sanctions in connection with a realistic strategy. Specifically, the United States should:

  • Reinstate some of the oil sanction waivers rescinded under the Trump administration that would allow Iran to legally export a limited amount of crude to buyers in Europe, South Korea, Japan, and India (U.S. allies and strategic partners). The profits from these sales could be held in escrow and used to help Iran engage in commerce.
  • Permit Iran to access a portion of its foreign reserves, which amounted to roughly $115 billion as of last year, now locked in overseas accounts due to U.S. banking sanctions.42 Approximately $7 billion of Iran’s money is frozen in South Korean banks; in order to add momentum to nuclear diplomacy, the United States could tell the South Korean government that Iran is allowed to use some of this money to finance debt payments or imports for non-military items.43

While the United States should move first, it should do so having received indications, presumably kept private, that Iran will respond with concrete nuclear concessions—suspending production of enriched uranium above 5 percent or exporting a portion of its stockpile of enriched uranium, for example. A step-by-step process initiated by the United States is the most likely sequence to secure a mutual return by both the United States and Iran to their JCPOA commitments.

If Iran refuses to engage, the United States need not overreact or double down on failed sanctions or other coercive measures. Diplomacy should continue regardless of whether the nuclear negotiations succeed or fail. Regular engagement is not a concession; the United States maintains relations with most states in the Middle East, many of which are just as autocratic and destabilizing as Iran. This is not because the United States accepts their conduct or agrees with their policies, but rather because contact is a prerequisite for constructive statecraft to advance U.S. interests and can prevent miscalculation. With Iran, diplomatic relations are important since the alternatives—sanctions, isolation, or preventive war—are ineffective or not worth the risks.

 

Use diplomacy to foreclose an unnecessary war

U.S. interests in the Middle East are narrow: (1) defend against anti-U.S. terrorist threats and (2) prevent significant, long-term disruptions to the global energy supply. The United States will remain secure and capable of fulfilling these interests no matter the status of the JCPOA. The actual threat Iran poses to the United States and its interests is minimal and takes little effort to thwart.

Iran is a middling power in the Middle East. With a gross domestic product of $191 billion, Iran’s economy is about the size of Nevada’s.44 Iran’s conventional ground forces are untested in battle since the Iran-Iraq War in the 1980s.45 While the Iranian missile program is improving in range and sophistication, its air force is antiquated and susceptible to modern air defense systems.46 Iran’s defense budget was $14.1 billion in 2020, nearly five times smaller than what Saudi Arabia and the United Arab Emirates spent combined.47 It is highly unlikely the Iranian military can close the Strait of Hormuz, through which one-third of worldwide sea-bound crude oil flows—and given Iran’s dependence on oil export revenue to finance its budget, Tehran has no incentive to do so.48 Iran’s chances of dominating the Persian Gulf’s oil supply are near zero.49 Outside of several non-state proxies and a beleaguered Syrian government that relies on Tehran for everything from military manpower to fuel subsidies, Iran has no allies to speak of and is surrounded by competitors, adversaries, and weak states.

Even with a nuclear program capable of producing a weapon, Iran may stop short of building a nuclear bomb due to the practical constraints of operating a nuclear arsenal. An Iranian nuclear arsenal, however small, could spur nuclear proliferation in the region as Saudi Arabia, Turkey, and Egypt seek to attain nuclear deterrents of their own.50 If Iran decides to build a bomb, the United States should implement a strategy of deterrence and crisis management, just as it has with other adversarial nuclear powers.

As many predicted, maximum pressure against Iran failed in every respect. Iran is enriching more uranium to higher levels, IAEA monitoring is curtailed, and Tehran’s foreign policy is more belligerent.51 The Biden administration’s decision to negotiate with Iran is a step in the right direction. But practical diplomacy from the U.S. side could keep the JCPOA intact and reduce the risks of a war that would drain U.S. resources, trap the U.S. military in the Middle East, and distract from higher priorities.
