Trump Pressures Oman to Abandon Neutrality and Sever Ties with Iran

President Donald Trump has issued a stark ultimatum to Oman, threatening military action if the sultanate does not align with U.S. interests in the Strait of Hormuz. The warning follows intelligence reports suggesting Muscat might facilitate Iranian efforts to levy tolls on commercial vessels, a claim the sultanate vehemently denies.

The threat marks a significant escalation in the Trump administration's cooling relations with a nation that has served as a primary diplomatic bridge between Washington and Tehran for decades. Treasury Secretary Scott Bessent has reinforced the pressure, signaling that the U.S. may impose sanctions if the Gulf state attempts to restrict maritime passage. While Omani Ambassador Talal Alrahbi has assured Washington that no such tolling plans exist, the administration continues to demand that Muscat formally cut its diplomatic ties with Iran.

Oman has long operated as a neutral mediator, successfully facilitating historic back-channel communications, including the 2015 nuclear pact. However, this strategy is currently under fire. U.S. officials argue that Oman’s refusal to explicitly condemn Iranian actions—coupled with its reticence to join regional security blocs—has rendered its impartiality indistinguishable from alignment with Tehran. According to Sanam Vakil of Chatham House, this shift in perception has stripped away the diplomatic cover that previously protected the sultanate from scrutiny.

Despite the aggressive rhetoric, internal assessments suggest the White House lacks an immediate plan to strike the country. Nevertheless, the diplomatic isolation of Muscat is deepening. Lacking the heavy military infrastructure or massive defense contracts held by neighbors like the UAE or Qatar, Oman finds its traditional role as a regional broker increasingly sidelined. As the Trump administration pushes for a definitive choice, the sultanate faces a precarious dilemma: aligning with Washington risks direct retaliation from Iran, while maintaining its current course invites further alienation from its oldest Western partner.
