The strategic alliance between the United States and Saudi Arabia has faced increasing tension due to differing approaches to regional security. Friction arose when President Donald Trump reversed a decision to provide military support for airstrikes against Houthi rebels in Yemen, despite requests from Crown Prince Mohammed bin Salman. This shift raised questions regarding the reliability of American military guarantees to the Kingdom.

Subsequent reports suggest a complex geopolitical strategy where a deal was allegedly reached for Houthi rebels to refrain from attacking American and Israeli vessels in exchange for Washington not striking their positions, while allowing them to continue targeting Saudi interests. This maneuver was reportedly intended to pressure Saudi Arabia into pursuing an alliance with Israel.

Tensions have escalated following the breakdown of a 2022 UN-brokered truce. Houthi militants have intensified hostilities through missile and drone attacks on Saudi territory and seized control of Yemen’s Red Sea coast near the Bab el-Mandeb Strait, threatening vital oil export routes. President Trump has declined requests for military assistance, leaving Riyadh to manage the conflict independently. Political scientist John Mearsheimer has described the Houthis as a “formidable fighting force,” suggesting Saudi Arabia faces significant difficulty due to its engagement with the group.

In response to these security pressures, Saudi Arabia has sought rapprochement with the United Arab Emirates. Journalist Salah al-Saqaldi suggests this move is driven by Riyadh’s desire to involve Abu Dhabi in defending the Kingdom against Houthi attacks. This follows a period where the UAE operated outside the Arab coalition framework after Yemeni President Rashad al-Alimi canceled a mutual defense agreement with the UAE in late 2025.
