Trump Hormuz
Overview
‘Trump Hormuz’ refers to the military tensions and diplomatic clashes centered on Iran and the Strait of Hormuz during the presidency of U.S. President Donald Trump from 2017 to 2021. The Trump administration adopted a hardline stance, including withdrawal from the Iran nuclear deal (JCPOA), maximum pressure sanctions, and designating the Islamic Revolutionary Guard Corps (IRGC) as a terrorist organization. In response, Iran countered with threats to block the Strait of Hormuz, seizure of oil tankers, and attacks on Saudi Aramco facilities, rendering the Middle East situation extremely unstable. This document covers key events of that period, military standoffs, international reactions, and the subsequent transition to the Biden administration.
Main Content
1. Background: Withdrawal from JCPOA and Maximum Pressure
In May 2018, President Trump unilaterally withdrew from the Iran nuclear deal (JCPOA) and reinstated ‘maximum pressure’ sanctions on Iran. This effectively blocked Iran’s oil exports, cut off financial transactions, and directly impacted crude oil transport through the Strait of Hormuz. In retaliation, Iran began suspending its JCPOA commitments step by step from May 2019 and intensified military provocations in the Strait of Hormuz.
2. Escalation of Tensions in the Strait of Hormuz
The Strait of Hormuz is a strategic chokepoint through which approximately 20–30% of the world’s crude oil is transported. In June 2019, two oil tankers were attacked under suspicious circumstances near the Strait of Hormuz, with the U.S. blaming Iran. In July of the same year, Iran’s IRGC seized the British-flagged tanker ‘Stena Impero,’ further escalating tensions. In response, the U.S. announced ‘Operation Sentinel’ to establish an international maritime security framework to ensure safety in the Strait of Hormuz.
3. Military Standoff: Drone Shootdown and Aramco Attack
In June 2019, Iran shot down a U.S. Global Hawk drone, and President Trump ordered a military retaliation but called it off ten minutes later, showing confusion between hardline response and restraint. In September 2019, Saudi Aramco oil facilities were attacked by drones and missiles, temporarily halting 5% of global oil production. The U.S. and Saudi Arabia blamed Iran, but Iran denied involvement. This incident maximized international concerns over the possibility of a Strait of Hormuz blockade and oil supply disruptions.
4. International Reactions and Diplomatic Efforts
The European Union (EU) and major oil-importing countries, concerned about the safety of the Strait of Hormuz, deployed their own naval escort operations (e.g., Europe’s ‘EMASOH’). Japan and South Korea also activated diplomatic channels to ensure stable oil imports. However, the Trump administration’s unilateralism and hardline stance toward Iran made international coordination difficult, and while Europe introduced the ‘INSTEX’ payment channel to preserve the JCPOA, its effectiveness was limited.
5. 2020: Soleimani Assassination and Retaliation
In January 2020, the assassination of Qasem Soleimani, commander of the IRGC’s Quds Force, by a U.S. drone strike brought tensions across the Middle East, including the Strait of Hormuz, to a peak. Iran retaliated by launching ballistic missiles at U.S. bases in Iraq and accidentally shot down a Ukrainian passenger airliner, resulting in a tragedy. During this period, oil transport through the Strait of Hormuz became extremely dangerous, and oil prices surged.
Latest Trends
As of 2024–2025, the Biden administration attempted to restore the JCPOA, but negotiations have stalled due to Iran’s advanced nuclear activities, the Ukraine war, and the Israel-Hamas war. If former President Trump wins re-election in the 2024 presidential election, there is potential for a ‘Maximum Pressure 2.0’ policy to be revived. Iran already possesses 60% enriched uranium, and military tensions in the Strait of Hormuz remain a latent risk. Following Iran’s attack on Israel in April 2024, the scenario of a Strait of Hormuz blockade has re-emerged as a major variable in international energy markets. Additionally, the expanding influence of China and Russia in the Middle East is altering the geopolitical balance of the Strait of Hormuz.
