Background
The term originates from the 1984 to 1988 phase of the Iran-Iraq War, when both sides targeted oil tankers and neutral merchant vessels in the Gulf. Iraq struck Iran's Kharg Island terminal to cut oil exports; Iran retaliated against ships serving Iraqi-allied Gulf States. The United States intervened under Operation Earnest Will, escorting Kuwaiti tankers through the strait.
The tanker war concept has returned to the Persian Gulf as Iran's IRGC imposes a toll system on the Strait of Hormuz and the Iran Defence Council has threatened to mine the entire waterway . Commercial shipping is again under direct attack, with Iranian drones striking Kuwait's Mina al-Ahmadi refinery for the first time and Brent Crude surging past $110 per barrel .
The 2026 iteration differs in scale and complexity. Twenty-two nations demanded Hormuz remain open but none pledged warships , leaving CENTCOM to shoulder the maritime mission alone. Meanwhile five nations are queuing to pay Iran's toll rather than challenge it , a dynamic without precedent in the original tanker war.
