Decades of Direct Confrontation
The modern pattern of direct military clashes between the United States and Iran began in the 1980s. In 1987 and 1988, the U.S. Navy conducted Operation Earnest Will, escorting Kuwaiti oil tankers reflagged under the American flag through the Persian Gulf. That operation led to skirmishes with Iranian forces. On April 18, 1988, the U.S. launched Operation Praying Mantis, during which American forces sank the Iranian frigate Sahand and damaged other vessels.
More recent confrontations have been stark. In 2011, the United States accused Iran of plotting to assassinate the Saudi ambassador in Washington, D.C. Tensions flared again in 2019 and 2020 under the Trump administration. The U.S. deployed the USS Abraham Lincoln carrier strike group to the region after what it described as alleged Iranian threats. On June 20, 2019, Iran shot down a U.S. RQ-4A Global Hawk drone over the strait. The United States planned a retaliatory strike but called it off minutes before impact. Then, in January 2020, a U.S. drone strike killed IRGC Quds Force commander Qasem Soleimani in Baghdad. Iran responded by launching ballistic missiles at U.S. bases in Iraq.
The history of tension between the two countries stretches back further, dating to the mid-19th century when Iran was known as Qajar Persia. But the current pattern of direct military clashes emerged from the 1980s, and subsequent decades saw a series of escalations including drone shootdowns, assassination plots, and airstrikes that killed Iranian commanders. The strait remains a flashpoint where any miscalculation could disrupt energy flows that power economies around the world.
Strategic Implications for Asia and Global Trade
For families and communities across Asia, the Persian Gulf is a vital artery for energy supplies and trade. The presence of Iran’s anti-ship missiles, including the Noor with a range of 130 km and the Khalij Fars with a range of 300 km, means the threat to commercial shipping is not abstract. These weapons, combined with Iran’s fast attack craft, create a layered challenge for naval forces trying to keep sea lanes open.
Any disruption in the Strait of Hormuz, where these naval forces operate, can send shockwaves through supply chains that reach as far as the Philippines, Indonesia, and Japan. Despite decades of regional conflict, the waterway had never been closed for an extended period before a major crisis in recent years, though Iran occasionally threatened to shut it and prepared to mine the channel. The strategic importance of the strait has shaped U.S. naval posture for generations, and the Fifth Fleet remains stationed in Bahrain with a typical force package of carriers, amphibious ships, and patrol aircraft.
The U.S. and Iran have not resolved the underlying tensions that have fueled these confrontations for nearly four decades. With the Fifth Fleet maintaining its posture in Bahrain and Iran’s naval forces continuing to operate in the gulf, the potential for another flashpoint remains. For communities that depend on the free flow of goods through these waters, the stakes could not be higher. The timeline of direct military clashes between the two nations is extensive, and the Strait of Hormuz continues to be a narrow passage where any miscalculation can have global consequences.
