A swift offensive by Yemen's Iran-aligned Houthi forces has placed the militants in a position to control the Bab el-Mandeb Strait, a vital Red Sea waterway. This development creates a significant challenge for U.S. President Donald Trump, who is already engaged in a seventh-month conflict with Iran and facing domestic political pressures.
The Houthi advance south along Yemen's coast has increased their ability to influence the Bab el-Mandeb, a chokepoint that connects the Red Sea to the Gulf of Aden. Control of this strait, often referred to as the "Gate of Tears," could provide Iran with leverage over key global energy shipping routes. This is particularly concerning for Saudi Arabia, which has been rerouting oil shipments through Red Sea ports after the conflict effectively closed the Strait of Hormuz.
The strategic threat comes at a difficult time for President Trump, who is navigating low approval ratings and seeking to de-escalate tensions with Iran. High gasoline prices, exacerbated by the ongoing conflict, have already jeopardized the Republican Party's prospects in the upcoming November midterm elections. Analysts suggest the Houthi actions could undermine Trump's strategy of economic pressure against Iran.
Stephen Wertheim, a senior fellow at Carnegie Endowment for International Peace, stated that the Houthi offensive "shattered Trump’s plan" to squeeze Iran's economy without escalating military conflict. The U.S. administration cannot afford disruptions to energy prices or global trade that would result from the closure of the Bab el-Mandeb Strait.
However, engaging militarily with the Houthis presents its own risks. The group has withstood previous attacks by Saudi Arabia and its allies, and a new U.S. intervention could stretch military resources already strained by the conflict with Iran. The U.S. military has been involved in Yemen, previously agreeing to halt bombing campaigns in exchange for a cessation of Houthi strikes on Red Sea shipping.
Crown Prince Mohammed bin Salman of Saudi Arabia reportedly requested U.S. military assistance in confronting the Houthis, but was informed that Washington would not intervene directly at this time, offering intelligence support instead. President Trump confirmed discussions with the Saudi crown prince and noted that the Houthis had also contacted his administration, requesting non-involvement.
A senior Trump administration official emphasized the U.S. focus on national security interests, including freedom of navigation in the Red Sea, while supporting regional partners. Iran's foreign ministry called for dialogue in Yemen, without directly addressing its own role in the conflict.
The closure of the Bab el-Mandeb Strait would impact approximately 7% of global oil supplies and about 12% of global trade, in addition to the disruption already occurring at the Strait of Hormuz. David Schenker, former Assistant Secretary of State for Near East Affairs, described this as a "worst-case scenario" that grants Iran significant leverage.
Trump faces a choice between committing U.S. forces and munitions to push back the Houthis or allowing Saudi Arabia and the Yemeni government to handle the threat independently. Direct U.S. military action could expose forces to missile attacks and deplete munitions stockpiles, though a senior administration official denied concerns about resource limitations.
Tim Lenderking, former U.S. special envoy on Yemen, suggested that without direct military involvement, the U.S. should increase intelligence sharing with Saudi Arabia and bolster diplomatic and material support for Yemen's recognized government. He noted that the situation in Yemen could significantly disrupt U.S. interests.
