Iran–United States relations during the first Trump administration (2017–2021) were marked by a sharp policy shift from Obama's engagement-oriented approach. Trump began with a travel ban affecting Iranian citizens, and withdrew from the Joint Comprehensive Plan of Action (JCPOA). A broader

followed, with over 1,500 sanctions targeting Iran’s financial, oil, and shipping sectors, as well as foreign firms doing business with Iran, severely damaging its economy. The effort aimed to isolate Iran but met with strong resistance—even from U.S. allies—and often left Washington diplomatically isolated. Iran responded by threatening to resume unrestricted uranium enrichment; rejecting negotiations with the Trump administration, and intensified rhetoric. Tensions escalated in 2019 with U.S. intelligence reports of Iranian threats, attacks on oil tankers, the downing of a U.S. drone by Iran, and suspected Iranian strikes on Saudi oil facilities. President Trump called off retaliatory strikes, opting for cyberattacks and additional sanctions instead. A major escalation followed a December 2019 rocket attack on the K-1 Air Basein Iraq, which led to American airstrikes on Iranian-backed militias and a retaliatory attack on the U.S. embassy in Baghdad. On 3 January 2020, the U.S. assassinated Iranian General Qasem Soleimani in a drone strike, prompting Iranian missile attacks on U.S. bases in Iraq and heightened fears of war. The crisis deepened with the accidental downing of a Ukrainian passenger plane by Iranian forces and continued through early 2020 with retaliatory strikes and threats. Later in 2020, Iran blamed U.S. sanctions for limiting its COVID-19 response. They launched a military satellite, and were later accused of interfering in the U.S. presidential election and proxy attacks. Relations ended under Trump with continued hostility and unresolved disputes.

At the outset of the first Trump administration in January 2017, Iran was led by President

, who held decisive power over Iran’s foreign and security policies. Relations between Iran and the United States were marked by cautious diplomacy following the 2015 nuclear agreement (JCPOA), but strained by ongoing U.S. sanctions, ballistic missile disputes, and regional tensions, with no formal diplomatic ties since 1980. Already during his presidential campaign, Trump maintained that "Iran is now the dominant Islamic power in the

Initial steps

One of the Trump administration’s first major actions affecting Iran came on 27 January 2017, when citizens of Iran and several other countries were temporarily banned from entering the United States by the executive order " Protecting the Nation From Foreign Terrorist Entry Into the United States". It barred Iranian citizens and individuals suspected of Iranian nationality from entering the U.S., including Iranian passport holders, except for transit. All passengers and crew, regardless of nationality, were required to ensure their passports contained no Iranian entry stamps. There are no direct flights between Iran and the USA so all travel must transit through a third country, and no Iranian aircraft may enter USA airspace. The Trump White House announced that it was putting Iran "on notice" following its ballistic missile tests on January 29, 2017, just days after taking office. Days later, the Trump administration imposed sanctions on 25 Iranian individuals and companies suspected of involvement in Iran's missile program, calling these "initial steps". The Trump administration was seen as moving to strengthen an informal coalition with Saudi Arabia, Israel, the United Arab Emirates and other Sunni Gulf states, aimed at countering Iran's regional influence. Between January and late July 2017,

Withdrawal from nuclear agreement and maximum pressure campaign

In May 2018, Donald Trump decided to pull out of the JCPOA, announcing he would reimpose economic sanctions on Iran effective from 4 November that year. This marked the beginning of the Trump administration's

The United States imposed over 1,500 sanctions, targeting Iran’s central bank, national oil company, shipping lines, and other key sectors, as well as foreign entities conducting business with Iran. The threat of secondary U.S. Treasury sanctions led many international corporations and financial institutions to disengage, contributing to a sharp decline in Iran’s oil exports.


IRGC and U.S. Armed Forces terrorist designations

The Iranian parliament responded by ratifying a motion designating "all legal and real persons and troops of the United States and its allies operating in the West Asian region" terrorists, calling any aid to them a terrorist act and pressing the government to defuse the threat of IRGC designation through multilateral negotiations with international organizations. The nonbinding resolution cited "the terrorist nature of the United States regime, particularly that part of the American military and security forces and the US Central Command which have been carrying out acts of terrorism in Iraq, Afghanistan, Syria, and Iran in the past quarter-century, and have given overt support to terrorist plans."

Drone incidents and cyber retaliation

Tensions between the U.S. and Iran escalated significantly in June 2019. On June 20, Iran shot down a U.S. RQ-4A Global Hawk drone, claiming it had violated Iranian airspace. The U.S. denied this, stating it was in international airspace.

November 2019 Iran gasoline price protests

On November 15, 2019, Iran raised gasoline prices by 50%, leading to violent protests across the country, with demonstrators calling for President Hassan Rouhani's resignation. The price hikes were driven by worsening economic conditions, partly due to U.S. sanctions. In response, the U.S. expressed support for the protesters and condemned the Iranian government.

According to Iranian sources, the drills were a response to recent U.S.–Saudi regional maneuvers and intended to show that Iran was not regionally isolated. In contrast, China's Ministry of National Defense described the exercise as a routine military exchange unrelated to international tensions.
In response to a series of attacks on Iraqi military bases, in particular the deadly strike on K-1 Air Base, U.S. forces launched airstrikes on 29 December targeting Kata'ib Hezbollah facilities in Iraq and Syria, despite the group's denial of involvement in the K-1 attack. The operation killed 25 militants and wounded at least 55 others. According to the U.S. Department of Defense, the strikes aimed to deter further assaults on coalition forces participating in Operation Inherent Resolve. At the time, approximately 5,000 U.S. troops were stationed in Iraq to support efforts against Islamic State remnants. Two days later, in a protest against the U.S. air strikes, the U.S. embassy in Bhagdad was attacked by Iraqi Shiite militiamen and their supporters. U.S. Defense Secretary Mark T. Esper stated that the United States would carry out pre-emptive strikes against Iranian-backed groups in Iraq and Syria if there are signs they are preparing further attacks on American forces or bases in the region.

Aftermath of Soleimani's assassination

Shortly after Soleimani's assassination, Trump ordered the deployment of 3,000 additional troops to the Middle East, adding to the 14,000 sent there since May 2019. Amid fears of a direct confrontation between the two nations, Trump warned Iran against attacking U.S. assets or any Americans in the region. He threatened that in the event of an Iranian attack, the U.S. would strike "very fast and very hard", targeting 52 Iranian sites, including cultural sites, as a symbolic response to the 52 American hostages taken by Iran in the 1979–81

On January 5, 2020, Iran declared it would no longer abide by the 2015 nuclear deal's limitations, but indicated it could return to compliance if sanctions were lifted. Iran also demanded the Iraqi parliament to get rid of the American presence in their country. In response to the assassination, the Iraqi parliament passed a resolution to expel all foreign troops, primarily targeting U.S. forces, though the vote was boycotted by Sunni and Kurdish lawmakers. In reaction, Trump threatened severe economic sanctions against Iraq, further straining U.S.-Iraqi relations. Rockets hit near the U.S. embassy and

During a press conference on 22 April, Pompeo said: "The Iranians have consistently said that these missile programs were disconnected from their military, that these were purely commercial enterprises.
