Trump’s Iran Policy: What You Need to Know

Prior to Donald Trump’s presidency, the cornerstone of international efforts to curb Iran’s nuclear program was the Joint Comprehensive Plan of Action (JCPOA), often referred to as the Iran nuclear deal. This agreement, signed in 2015 between Iran and the P5+1 (China, France, Germany, Russia, the United Kingdom, and the United States), aimed to prevent Iran from developing nuclear weapons in exchange for relief from international sanctions. The deal imposed significant restrictions on Iran’s nuclear activities, including caps on uranium enrichment levels, limits on centrifuges, and enhanced international inspections. Proponents of the JCPOA argued that it was the most effective means of preventing a nuclear-armed Iran, while critics contended it did not go far enough to address Iran’s missile program or its regional influence.

Criticisms of the JCPOA

From the outset, Trump and many of his advisors expressed strong disapproval of the JCPOA. Their criticisms centered on several key areas. First, they argued the deal had “sunset clauses,” provisions that would allow some restrictions on Iran’s nuclear program to expire over time, potentially enabling Iran to resume its nuclear weapons development after a certain period. This was viewed as a critical flaw, a ticking clock towards a nuclear Iran, rather than a permanent solution.

Second, critics highlighted the agreement’s failure to address Iran’s ballistic missile program. Iran continued to develop and test ballistic missiles, which were seen as a direct threat to regional stability and an avenue for delivering any future nuclear weapons. The deal’s narrow focus on nuclear technology, while ignoring this other proliferation risk, was a significant point of contention.

Third, concerns were raised about Iran’s destabilizing activities in the Middle East. Trump administration officials frequently cited Iran’s support for various non-state actors, including Hezbollah in Lebanon and Houthi rebels in Yemen, as evidence of its malign behavior. The JCPOA, they argued, provided Iran with economic relief that could be used to fund these activities, effectively empowering a hostile regime.

The Withdrawal Decision

Despite appeals from European allies to remain in the agreement, President Trump announced the United States’ withdrawal from the JCPOA on May 8, 2018. This decision marked a significant shift in U.S. foreign policy towards Iran. Trump described the deal as “horrible” and “an embarrassment,” stating that it did not adequately protect American national security interests. He asserted that a new, stronger agreement was necessary, one that would address all aspects of Iran’s behavior, not just its nuclear program. This withdrawal initiated a path of maximum pressure, rather than cooperative engagement.

The “Maximum Pressure” Campaign

Following the withdrawal from the JCPOA, the Trump administration launched what it termed a “maximum pressure” campaign against Iran. This strategy aimed to compel Iran to negotiate a new, broader agreement by imposing severe economic sanctions and increasing diplomatic isolation. The underlying principle was to apply enough economic pain to force a change in Iran’s behavior, believing that a crippled economy would leave Tehran with no choice but to accede to American demands.

Re-imposition and Escalation of Sanctions

The core of the maximum pressure campaign was the re-imposition of sanctions that had been lifted under the JCPOA, as well as the implementation of new, expanded sanctions. These sanctions targeted various sectors of the Iranian economy, with a particular focus on its oil exports, financial institutions, and shipping industry.

• Oil Sanctions: The administration aggressively pursued measures to cut off Iran’s ability to sell oil, which is a primary source of revenue for the Iranian government. Waivers for certain countries to continue purchasing Iranian oil were eventually phased out, aiming to bring Iran’s oil exports to zero. This was intended to choke off the regime’s financial lifeline.
• Financial Sanctions: Iranian banks and financial institutions were placed under severe restrictions, making it difficult for Iran to conduct international trade and access global financial markets. This created a significant impediment to Iran’s ability to import essential goods and conduct foreign transactions. The US Treasury Department’s Office of Foreign Assets Control (OFAC) played a central role in identifying and sanctioning entities linked to the Iranian government or its illicit activities.
• Sectoral Sanctions: Beyond oil and finance, sanctions were extended to other critical sectors, including petrochemicals, construction, and metals. The goal was to systematically degrade Iran’s economic capacity across the board, leaving no major industry untouched.

Diplomatic Isolation and Regional Alliances

Alongside economic measures, the Trump administration sought to diplomatically isolate Iran and strengthen regional alliances against it. This involved increased engagement with Gulf Arab states and Israel, entities that share concerns about Iran’s regional influence.

• GCC and Israel: The U.S. worked to solidify its relationships with the Gulf Cooperation Council (GCC) countries (such as Saudi Arabia and the United Arab Emirates) and Israel, encouraging them to form a united front against Iranian aggression. This involved sharing intelligence, coordinating military exercises, and fostering a narrative of Iran as the primary destabilizing force in the region.
• International Pressure: The administration also urged other countries, particularly European allies, to join the maximum pressure campaign. While European nations largely opposed the U.S. withdrawal from the JCPOA, they often found themselves in a difficult position, caught between their allegiance to the multilateral agreement and their strategic relationship with the United States. They often attempted to find alternative mechanisms for trade with Iran, such as the INSTEX (Instrument in Support of Trade Exchanges) special purpose vehicle, though these efforts had limited success.

Escalation and Crises

The maximum pressure campaign, rather than leading to immediate capitulation from Iran, instead resulted in a series of escalations and crises in the Persian Gulf region. This period was characterized by a dangerous cycle of action and reaction, frequently bringing the two nations to the brink of direct conflict.

Attacks on Shipping and Infrastructure

Iran responded to the intensifying sanctions with actions aimed at demonstrating its resolve and its capability to disrupt regional stability. These actions often targeted critical infrastructure and international shipping, threatening global oil supplies.

• Tanker Attacks: In mid-2019, a series of attacks on oil tankers in the Gulf of Oman and near the Strait of Hormuz were attributed by U.S. intelligence to Iran. These incidents, involving limpet mines and other methods, significantly raised concerns about the safety of maritime navigation in a crucial global shipping lane.
• Saudi Oil Facilities: In September 2019, major drone and missile attacks targeted two key oil processing facilities in Saudi Arabia, Abqaiq and Khurais. While the Houthi rebels in Yemen claimed responsibility, the U.S. and Saudi Arabia asserted that Iran was behind the sophisticated attacks, which temporarily halved Saudi Arabia’s oil production and sent global oil prices soaring. This event demonstrated Iran’s potential to inflict significant damage on energy infrastructure.

The Downfall of a U.S. Drone

In June 2019, Iran’s Islamic Revolutionary Guard Corps (IRGC) shot down a U.S. Navy RQ-4A Global Hawk surveillance drone over the Strait of Hormuz. Iran claimed the drone had violated its airspace, a claim the U.S. denied, stating the drone was in international airspace. This incident brought the U.S. and Iran to the precipice of military conflict, with President Trump reportedly halting retaliatory strikes against Iran at the last minute. This close call underscored the volatile nature of the standoff and the potential for miscalculation.

Assassination of Qassem Soleimani

The most significant escalation occurred in January 2020, with the U.S. drone strike that killed Qassem Soleimani, the commander of the IRGC’s Quds Force, near Baghdad International Airport. Soleimani was a highly influential figure in Iran and a key architect of its regional foreign policy and proxy networks.

• U.S. Justification: The Trump administration justified the strike by claiming Soleimani was planning “imminent attacks” on U.S. personnel and interests in the region. They argued it was a defensive measure to prevent further American deaths.
• Iranian Retaliation: Iran retaliated by launching ballistic missiles at Iraqi military bases housing U.S. troops, specifically Al-Asad Airbase and a base near Erbil. While there were no immediate fatalities from these strikes, over 100 U.S. service members subsequently suffered traumatic brain injuries. This direct military response from Iran demonstrated its willingness to engage in direct action against U.S. forces, albeit within certain limitations to avoid an all-out war. The subsequent missile strike on a Ukrainian passenger jet by Iranian air defenses, initially concealed, added another layer of tragedy and mistrust to the situation.

The Diplomatic Standoff

Despite the public rhetoric and the maximum pressure campaign, the Trump administration occasionally indicated a willingness to negotiate with Iran. However, several factors contributed to a persistent diplomatic standoff, akin to two immovable objects meeting, preventing any meaningful dialogue or de-escalation that could lead to a new agreement.

Iran’s Conditions for Talks

Iran, while not rejecting the idea of talks outright, consistently set preconditions that were largely unacceptable to the U.S. The primary condition was the lifting of sanctions as a prerequisite for any new negotiations. Iranian officials argued that they would not negotiate “under duress” and that the U.S. must return to the JCPOA before any broader discussions could take place. They viewed the sanctions as an act of economic warfare, and saw any talks under such conditions as a surrender, not a negotiation among equals.

U.S. Conditions for Talks

Conversely, the U.S. maintained that sanctions would only be lifted as part of a new, comprehensive agreement that addressed all its concerns. The Trump administration outlined a list of 12 demands, often referred to as Pompeo’s 12 Demands, which included:

• Ending Uranium Enrichment: Demanding Iran cease all uranium enrichment and reprocessing activities.
• Full Disclosure of Nuclear Activity: Requiring Iran to provide the IAEA with full access to all sites and disclose all nuclear activities.
• Ending Ballistic Missile Proliferation: Insisting Iran stop proliferating ballistic missiles and halt their development.
• Releasing U.S. Citizens: Demanding the release of all U.S. citizens unjustly detained in Iran.
• Ending Support for Terrorism: Calling on Iran to end its support for designated terrorist organizations and proxy groups.
• Respecting Sovereignty: Requiring Iran to respect the sovereignty of its neighbors and end military excursions across the region.

These demands were far-reaching and effectively sought a fundamental shift in Iran’s foreign and defense policies, which Iran viewed as an infringement on its sovereignty and national security. The gap between the two sides’ preconditions created an impassable diplomatic chasm.

Limited Intermediary Efforts

Despite the direct standoff, there were intermittent attempts by third parties to facilitate dialogue. European leaders, particularly French President Emmanuel Macron, engaged in shuttle diplomacy, attempting to bridge the gap between Washington and Tehran. There were also reports of back-channel communications through countries like Switzerland and Oman. However, these efforts yielded no significant breakthroughs, as neither side was willing to compromise on its fundamental positions. The diplomatic channels, though present, were effectively choked off by the preconditions.

Legacy and Future Implications

The Trump administration’s Iran policy constituted a radical departure from previous U.S. approaches and left a complex and volatile legacy that continues to shape the geopolitical landscape of the Middle East. It rewrote the playbook, but without a definitive conclusion.

Impact on Iran’s Nuclear Program

One of the stated goals of the maximum pressure campaign was to prevent Iran from developing nuclear weapons. However, the withdrawal from the JCPOA and the subsequent sanctions had the unintended consequence of driving Iran to progressively reduce its compliance with the agreement’s restrictions.

• Increased Enrichment: Iran began enriching uranium beyond the limits stipulated by the JCPOA, both in terms of purity and quantity. It also reactivated centrifuges that had been mothballed and experimented with advanced centrifuge designs. These actions, undertaken in response to the U.S. withdrawal and perceived lack of economic benefits, brought Iran closer to a breakout capability (the time it would take to acquire enough fissile material for a nuclear weapon).
• Reduced Inspections: Iran also took steps to limit the access of International Atomic Energy Agency (IAEA) inspectors, further complicating international monitoring efforts. This created a dimmer picture for the international community regarding the true extent of Iran’s nuclear activities.

This effectively put Iran on a faster track towards greater nuclear capability, a counterintuitive outcome for a policy aimed at preventing a nuclear Iran. It was a situation akin to closing one door to a room, only to see several windows open elsewhere.

Regional Instability and Proxy Conflicts

The maximum pressure campaign and the resulting escalations undoubtedly exacerbated regional instability. The tit-for-tat actions, the attacks on infrastructure, and the assassination of Soleimani heightened tensions and increased the risk of broader conflict.

• Proxy Warfare: Iran continued to support its regional proxies, viewing them as a crucial deterrent against external threats and a means to project influence. The economic pressure did not deter, and in some cases, may have emboldened, these networks.
• Arms Race Concerns: The heightened tensions also fueled concerns about a regional arms race, with countries like Saudi Arabia potentially seeking their own nuclear capabilities if Iran were to develop one. The security dilemma, where one state’s security measures are perceived as aggressive by others, was sharply in focus.

Challenges for Future Administrations

The Trump administration’s Iran policy presented significant challenges for subsequent U.S. administrations. Any future policy would need to grapple with:

• Restoring Trust: The U.S. withdrawal from the JCPOA severely damaged its credibility as a reliable international partner, particularly with European allies. Rebuilding that trust would be a formidable task.
• Managing Escalation: The risk of conflict in the Persian Gulf remains high, requiring careful diplomatic and military management to prevent further escalation. The infrastructure of peace remains fragile.
• Addressing Iran’s Nuclear Advances: Iran’s nuclear program has advanced significantly since the U.S. withdrawal from the JCPOA. Any new agreement would need to address these advancements and provide verifiable assurances against weaponization. This is not simply turning back the clock; it is recognizing that the clock has advanced.
• Beyond Nuclear: The broader challenges of Iran’s ballistic missile program and its regional activities would also need to be addressed, as these were core reasons for the Trump administration’s departure from the JCPOA.

In conclusion, Trump’s Iran policy, characterized by its aggressive maximum pressure campaign and withdrawal from the JCPOA, represented a profound shift in U.S. engagement with Iran. While aiming to compel Iran to a more comprehensive agreement, it instead led to increased nuclear non-compliance, heightened regional tensions, and a complex diplomatic quagmire for future policymakers. The legacy is one of increased risk and a more challenging path towards de-escalation and long-term stability in the Middle East.
