Gulf geopolitical tensions escalate as Saudi-Bahrain causeway reopens amid Iran-Saudi proxy conflict

Indigenous Gulf communities historically relied on seasonal migration and trade networks that transcended modern borders, with causeways like the King Fahd serving as artificial divisions rather than neutral connectors. The current conflict framing ignores how these communities’ livelihoods—fishing, pearl diving, and date farming—are disrupted by militarized infrastructure. Traditional mediation practices among Gulf tribes, which once resolved disputes without state intervention, have been sidelined in favor of hard security approaches.

The Saudi-Iran rivalry traces back to the 1979 Iranian Revolution, when Saudi Arabia positioned itself as the guardian of Sunni Islam against revolutionary Shi’a Iran. The causeway itself was inaugurated in 1986, a period when Gulf states were consolidating alliances against Iran during the Iran-Iraq War. U.S. military bases in Bahrain and Saudi Arabia since the 1990s have further entrenched a security paradigm that treats infrastructure as strategic assets rather than shared resources.

In the Arabian Gulf, causeways are not just physical structures but cultural artifacts reflecting power asymmetries—Bahrain’s Sunni monarchy uses the causeway to assert control over its Shi’a-majority population with Saudi backing. Iranian narratives frame the causeway as part of a Saudi-American axis to encircle Iran, while Bahraini opposition groups see it as a tool of economic dependency. In contrast, Oman’s historical role as a mediator in Gulf conflicts highlights an alternative model of regional cooperation that prioritizes dialogue over militarization.

Ballistic missile attacks on critical infrastructure are a documented tactic in asymmetric warfare, often used to signal resolve without triggering full-scale conflict. Studies show that such attacks disproportionately affect civilian economies, particularly in energy-dependent regions like the Gulf, where disruptions can trigger price volatility in global oil markets. The causeway’s reopening reflects a calculated risk assessment by Gulf states to balance deterrence with economic continuity, despite the lack of empirical evidence that such attacks alter long-term geopolitical outcomes.

In Gulf poetry and oral traditions, causeways and bridges are metaphors for both connection and division, reflecting the duality of human relationships. Bahraini artists like Ahmed Qasim have depicted the causeway as a symbol of oppression, while Saudi artists often portray it as a triumph of modernity. The spiritual dimension of this conflict lies in the way Gulf states weaponize religious identity—Sunni vs. Shi’a—to justify securitization, erasing the shared cultural heritage that once defined the region.

Scenario modeling suggests that continued militarization of Gulf infrastructure could lead to a feedback loop of retaliatory attacks, with the causeway becoming a recurring flashpoint in Saudi-Iran proxy conflicts. Alternative futures include the formation of a Gulf-wide energy and water sharing compact, where infrastructure is treated as a public good rather than a strategic asset. Climate change further complicates this dynamic, as water scarcity and energy transitions may force Gulf states to prioritize regional cooperation over zero-sum competition.

Bahraini human rights activists argue that the causeway’s reopening enables Saudi interference in Bahrain’s internal affairs, particularly in suppressing Shi’a dissent. Migrant laborers from South Asia, who constitute a majority of the causeway’s users, are rarely consulted on security policies that directly impact their livelihoods. Iranian dissidents within Bahrain’s Shi’a community are caught in a double bind, facing repression from both Bahraini and Saudi authorities while being accused of Iranian allegiance.
