Iranian military forces initiated attacks against commercial vessels in the Strait of Hormuz following February 28, 2026 clashes with the United States and Israel, asserting unprecedented administrative control over the maritime choke point. Tehran cited a June 2026 memorandum of understanding committing Iran to arrange safe passage for shipping as legal justification to redirect vessels into its territorial waters.
This unilateral posture disrupted global energy transport from the Persian Gulf, prompting U.S. Central Command to implement naval blockades, conduct strikes on Iranian assets, and attempt alternative southern routing via Omani waters under Project Freedom. While an International Maritime Organization evacuation facilitated vessel exits, renewed hostilities in July 2026 highlighted persistent instability. Future scenarios facing U.S. policymakers range from direct military action to establish maritime control along the Iranian coast, to formal multilateral navigation management agreements, or strategic asset reprioritization away from the Gulf.
