Geopolitical calculus: Why US military restraint in Strait of Hormuz reflects energy security trade-offs and regional deterrence failures

Indigenous and local maritime communities along the Gulf possess centuries of ecological and navigational knowledge about the Strait’s currents, seasonal winds, and historical trade routes, yet their insights are excluded from geopolitical analyses. Traditional pearl divers and fishermen in Iran, Oman, and UAE understand the Strait’s rhythms in ways that elude satellite surveillance and military modeling. Their exclusion reflects a broader erasure of non-state, place-based knowledge in favor of state-centric security paradigms.

The Strait of Hormuz has been a geopolitical flashpoint since the 7th century, when Arab-Islamic empires controlled its trade routes, and later during European colonial expansions. The 1953 US-British coup against Iran’s democratically elected government seeded lasting distrust in Tehran toward Western powers. The 1980s ‘Tanker War’ during the Iran-Iraq conflict established patterns of asymmetric retaliation that Iran has since refined, yet these historical precedents are rarely contextualized in modern analyses.

In Shia Islamic eschatology, the Strait of Hormuz is linked to prophecies of final battles, framing Iran’s actions as divinely sanctioned resistance—a narrative absent in Western secular strategic thought. Gulf Arab states like Oman and Qatar have historically mediated tensions, advocating for dialogue over confrontation, reflecting a pluralistic approach to regional security. Iranian strategists often invoke the concept of ‘defensive deterrence’ (defa’), which prioritizes asymmetric capabilities over conventional parity, a framework misunderstood in Western military doctrine.

The Strait’s narrowness (21 nautical miles wide) and depth (60–90 meters) make it vulnerable to blockades, yet its ecological fragility—home to endangered species like the dugong—is rarely considered in military risk assessments. Satellite tracking of tanker traffic (e.g., via AIS data) reveals Iran’s precision in targeting without full blockades, suggesting calibrated asymmetric warfare rather than irrational aggression. Energy security models often underestimate how sanctions disrupt global oil flows, as seen in 2019 attacks on Saudi Aramco facilities, which were linked to Iranian-backed groups.

Persian poetry and Islamic art often depict the Strait as a metaphor for resilience, such as in the works of Hafez or the calligraphy of the Quranic verse ‘And We have made the sea a sign’ (Quran 21:31). Gulf maritime festivals, like Oman’s ‘Khareef’ season, celebrate the Strait’s cultural and ecological significance, framing it as a shared heritage rather than a contested zone. Western media’s militarized imagery contrasts sharply with these spiritual and artistic representations, revealing a clash of ontologies.

Scenario modeling suggests that a full blockade of the Strait could trigger a 30–50% spike in global oil prices, destabilizing economies reliant on Gulf oil, yet most analyses focus on short-term military responses. Climate change exacerbates risks, as rising sea levels and extreme weather could disrupt shipping lanes, making the Strait even more critical—and contentious. Future US military restraint may reflect recognition that kinetic action could accelerate Iran’s nuclear ambitions or provoke wider regional war, a calculus often omitted in hawkish narratives.

Gulf labor migrants, who constitute 80% of the UAE’s workforce, face heightened risks during conflicts but are rarely consulted in security debates. Iranian women’s rights activists argue that sanctions and military posturing disproportionately harm civilians, yet their perspectives are excluded from geopolitical analyses. Omani and Qatari diplomats, who have mediated past crises, are sidelined in favor of US-Israel security frameworks, reflecting a broader marginalization of Gulf states’ agency.
