Gulf States Brace for Fallout as US Military Buildup in the Persian Gulf Reaches Levels Unseen Since 2003

As the United States deploys the largest concentration of military assets to the Middle East since Operation Iraqi Freedom, the Gulf Cooperation Council states find themselves caught in an increasingly precarious position. With tensions between Washington and Tehran escalating to dangerous levels, America's traditional Arab allies are not cheering from the sidelines but rather engaging in frantic diplomatic efforts to prevent a conflict they believe could destabilize the entire region for decades to come.

The scale of the American military mobilization is unprecedented for the post-Iraq War era. According to multiple defense sources and satellite imagery analysis, the United States currently maintains two carrier strike groups in the region, comprising 14 surface warships—the largest naval concentration in Middle Eastern waters since five carrier battle groups assembled in March 2003. The buildup includes at least 108 aerial refueling tankers either stationed in or en route to the CENTCOM theater of operations, a logistical capability that military analysts say enables sustained, long-duration air operations rather than limited, one-off strikes.

The force posture extends well beyond naval assets. The Pentagon has significantly reinforced air bases across the region, with particular emphasis on installations believed to be outside the range of Iran's shorter-range ballistic missiles. The New York Times reported on February 22 that a substantial portion of advanced F-35 Lightning II fighters have been deployed to the Muwaffaq Salti Air Base in Jordan, a facility that has recently received upgraded air defense systems including additional Patriot missile batteries. Current estimates place between 30,000 and 40,000 American military personnel at 13 bases throughout the Middle East, all of which the Pentagon acknowledges are potential targets for Iranian retaliation.

This massive deployment follows months of escalating tensions that began with widespread protests in Iran in late 2025 and early 2026. On January 15, President Donald Trump vowed to support what he termed "freedom fighters" in Iran and warned the Islamic Republic's leadership that military intervention remained "firmly on the table." While those protests have since been violently suppressed by Iranian security forces, Trump has maintained his confrontational posture, most recently telling reporters on February 20 that Iran has "10 to 15 days to make a deal" before facing potential military action.

For the Gulf states—Saudi Arabia, the United Arab Emirates, Qatar, Kuwait, Bahrain, and Oman—the prospect of American military strikes on Iran represents an existential dilemma. These nations have spent years carefully balancing their security dependence on Washington with economic pragmatism toward Tehran. Now they face the very real possibility that facilities on their territory hosting American forces could become targets of Iranian missile barrages, while their carefully cultivated economic diversification strategies could collapse overnight as investors and expatriate talent flee the region.

The threat is not theoretical. On February 5, Iran's Islamic Revolutionary Guard Corps Navy announced it had seized two foreign oil tankers near Farsi Island in the Persian Gulf, transferring them to Bushehr port under claims of fuel smuggling. More ominously, Iranian officials have issued explicit warnings about potential retaliatory targets. In a letter to the United Nations Secretary-General on February 20, Iran's UN mission stated that "all bases, facilities, and assets of the hostile force in the region would constitute legitimate targets" in the event of an American attack, adding that "the United States would bear full and direct responsibility for any unpredictable and uncontrolled consequences."

These are not idle threats. The June 2025 U.S. strike on three Iranian nuclear facilities during the brief "Twelve-Day War" prompted an Iranian missile strike on Al Udeid Air Base in Qatar. Though that attack produced no casualties, regional leaders view it as a restrained response compared to what might follow a more extensive American campaign. Saudi Arabia's experience with Iranian capability remains fresh: in September 2019, drone and cruise missile strikes attributed to Iran temporarily crippled approximately half of the kingdom's oil production capacity, demonstrating Tehran's ability to strike deep into Gulf Arab territory with devastating economic effect.

Recognizing these dangers, Gulf leaders have engaged in unprecedented diplomatic activism. Saudi Crown Prince Mohammed bin Salman personally communicated to Iranian President Masoud Pezeshkian that the kingdom would not permit its airspace or territory to be used for attacks on Iran. The UAE, through senior adviser Anwar Gargash, has publicly called for a "long-term diplomatic solution between Washington and Tehran." Oman, which maintains functional diplomatic relations with both Washington and Tehran, has intensified its traditional mediator role, hosting multiple rounds of negotiations in recent weeks.

The economic stakes for the Gulf states are staggering. These nations have invested hundreds of billions of dollars in economic diversification programs designed to reduce dependence on hydrocarbon revenues and position themselves as global business and tourism hubs. The UAE's Vision 2030, Saudi Arabia's Vision 2033, and similar programs in Qatar and Bahrain all depend on political stability, investor confidence, and the continued flow of international talent to cities like Dubai, Riyadh, and Doha. A regional war would send insurance premiums soaring, freeze foreign investment, and potentially trigger capital flight on a scale not seen since the 1990-1991 Gulf War.

The energy dimension compounds these concerns. Approximately 21 percent of global petroleum passes through the Strait of Hormuz, the narrow waterway separating Iran from the Arabian Peninsula. While a complete Iranian closure of the strait appears unlikely—as it would severely damage Iran's own oil exports to China, its primary economic lifeline—Iranian military officials have recently conducted exercises for what they term a "smart closure." This strategy would involve selective interdiction of Western-linked tankers while allowing Chinese-flagged vessels to pass, similar to Houthi tactics in the Red Sea. Even the threat of such action would dramatically increase shipping insurance costs and contribute to global oil price volatility, with direct implications for inflation rates worldwide.

Beyond immediate security and economic concerns, Gulf leaders harbor deeper strategic anxieties about the regional order that might emerge from an American-Iranian confrontation. Despite decades of rivalry with Tehran, Arab Gulf states increasingly view the potential collapse of the Iranian state as potentially more destabilizing than its continued existence as a weakened adversary. As Galip Dalay of Chatham House noted in analysis published February 21, regional leaders now view "an expansionist and aggressive Israel, and the chaos of a potentially collapsed Iranian state" as greater long-term threats than current Iranian regional ambitions.

This assessment reflects a fundamental shift in regional threat perceptions. Israel's military dominance has grown substantially following the collapse of Syrian military power, the severe degradation of Lebanese Hezbollah's capabilities through years of conflict, and the effective neutralization of Palestinian armed groups. In this context, some Arab leaders privately express concern that the complete elimination of Iranian power projection capabilities would remove the primary counterweight to Israeli military supremacy in the Levant, potentially emboldening more aggressive Israeli policies that Gulf states would be powerless to influence.

The humanitarian dimension adds another layer of concern. A sustained American military campaign against Iran, particularly one aimed at regime change rather than limited counter-proliferation objectives, could trigger massive refugee flows. Dubai lies only 140 kilometers across the Persian Gulf from the Iranian port of Bandar Abbas—a short boat journey that could become a refugee corridor if Iran's economy collapses or internal conflict erupts. Gulf states, with their relatively small citizen populations and large expatriate workforces, possess limited capacity to absorb sudden refugee influxes without triggering domestic political and social pressures.

For Iraq, the situation presents an acute crisis of sovereignty and identity. As a Shia-majority nation with extensive political, economic, and religious ties to Iran, Iraq faces the possibility of becoming a battleground despite its desperate desire to remain neutral. While major Shia political factions comprising the Shiite Coordination Framework, including Nuri al-Maliki's State of Law Coalition and Hadi al-Ameri's Fatah Alliance, view American-Iranian conflict on Iraqi soil as an existential threat to their fragile sovereignty, smaller hardline groups like Kataib Hezbollah might feel compelled to attack American forces in Iraq as a show of solidarity with Tehran. Baghdad's nightmare scenario involves a return to the sectarian violence and state failure that followed the 2003 U.S. invasion, from which Iraq has still not fully recovered.

Against this backdrop, negotiations between Washington and Tehran continue, though with uncertain prospects. Iranian Foreign Minister Abbas Araghchi stated in interviews on February 21 that any agreement "should be a win-win deal... It needs to accommodate both sides' interests and concerns." The Trump administration has demanded that Iran accept "zero enrichment"—complete cessation of uranium enrichment activities within Iranian territory. Tehran has offered various alternatives, including a three-to-five-year enrichment suspension or placing enrichment activities under joint regional control, but these proposals have been rejected by Washington as insufficient to permanently block pathways to nuclear weapons development.

Reporting suggests the Trump administration may be willing to accept "small, token enrichment" if Iran provides "very detailed" proof that its nuclear program remains entirely civilian in nature. However, the political bar for Trump remains high: any agreement must be demonstrably stricter than the 2015 Joint Comprehensive Plan of Action that Trump withdrew from during his first presidential term. Accepting anything less would expose Trump to domestic political criticism that he had capitulated to the same Iranian government he has spent years condemning.

Military options under consideration reportedly range from limited strikes on specific targets to extended campaigns lasting weeks or months. The Wall Street Journal reported on February 21 that one option involves a limited initial strike on a few military or government sites, designed to pressure Tehran into accepting U.S. terms while falling short of triggering major Iranian retaliation. If this fails to produce Iranian compliance, Trump could then escalate to a broader campaign targeting regime facilities. Other options reportedly include a naval quarantine of Iranian oil exports—technically an act of war under international law that Iran would almost certainly challenge militarily—or even a "decapitation strike" aimed at eliminating Supreme Leader Ayatollah Ali Khamenei and his inner circle.

Notably absent from published reports is any indication that the ground forces necessary for regime change operations are being deployed to the region. This suggests that while Trump has assembled the capability for extensive air and naval operations, a full-scale invasion aimed at occupying Iran and forcibly installing a new government is not currently under serious consideration. Such an operation would require hundreds of thousands of troops and likely face fierce resistance in a nation of 89 million people with mountainous terrain and a long history of military resistance to foreign intervention.

The coming days may prove decisive. With Trump's self-imposed "10 to 15 day" deadline rapidly approaching and military assets now in position for sustained operations, regional leaders face the growing likelihood that diplomatic efforts will fail and military action will commence. If that occurs, the Gulf states will find themselves on the front lines of a conflict they neither wanted nor believe serves their long-term interests—hosting American bases that become Iranian targets while watching their economic development strategies collapse and their carefully constructed regional order dissolve into chaos.

As Anna Jacobs Khalaf of the Arab Gulf States Institute observed, Gulf leaders "may like to see the Iranian leadership weakened, but all of them are more concerned about a scenario of chaos and uncertainty and the possibility of more radical elements coming to power there." In the dangerous game of brinkmanship now unfolding across the Persian Gulf, America's traditional allies increasingly find themselves hoping not for victory, but simply for restraint before it is too late.
