Trump’s Iran Deal Has Collapsed, Leaving the U.S. With Few Good Options

Council on Foreign Relations  |  Max Boot

President Donald Trump reinstated the United States blockade on Iranian oil and threatened a 20 percent cargo toll after Iran closed the strategic Strait of Hormuz. This rapid escalation followed intense retaliatory airstrikes between both nations, effectively collapsing the bilateral memorandum of understanding signed at Versailles on June 18.

The short-lived agreement had offered Tehran billions of dollars in sanctions relief and reconstruction assistance in exchange for unhindered commercial shipping and nuclear negotiations. However, Iranian hard-liners rejected these terms, leveraging their geographic control over the waterway to demand transit fees and assert regional dominance. Despite earning $5 billion in oil exports during the brief sanctions pause, the regime resumed hostile operations against merchant vessels. With 60 percent of the American public opposing the conflict, Washington lacks the domestic support required for a large-scale military intervention to force regime change. Consequently, the administration faces an unpalatable choice between accepting Iranian maritime blackmail or risking a highly dangerous regional military escalation.

Comment
Maritime chokepoints remain highly vulnerable to asymmetric denial strategies. Naval blockades require sustained coalition support to secure international shipping lanes. Limited aerial strikes cannot degrade decentralised missile programmes or force political capitulation. Regional states must therefore develop independent maritime escort capabilities to safeguard their energy security.
