Oman's Diplomatic Role Tested Amid Trump-Era Iran Conflict

Core Event: U.S.–Iran hostilities and the Strait of Hormuz dispute
The United States and Iran have been locked in a naval standoff since late February 2026, when Tehran began closing the Strait of Hormuz with drone, small-boat and mine attacks. The strait, which carries roughly one-fifth of global oil and LNG shipments, remains under a U.S. blockade despite the expiration of the deadline for an interim U.S.–Iran agreement earlier this week. President Donald Trump has threatened to declare the waterway U.S. territory and claims mines have been cleared, while commercial traffic stays far below pre-war levels.
Background & Context: Oman’s historic ties with Washington and Tehran
Oman’s relationship with the United States dates to a 1833 Treaty of Amity and Commerce. In 1980 Oman became the first Gulf state to grant Washington access to its military facilities, and in 2019 the ports of Duqm and Salalah were added for U.S. resupply. Oman maintains a “neutral” policy, keeping diplomatic channels with Iran, the Houthis, Saudi Arabia, the UAE and Israel, and has served as a back-channel for U.S.–Iran nuclear talks.
