Abu Musa Island: Strategic Heart Of The Persian Gulf Dispute

In the vast expanse of the Persian Gulf, where ancient trade routes meet modern geopolitical complexities, lies a small but immensely significant piece of land: Abu Musa Island. This unassuming speck of territory has, for decades, been a focal point of contention, embodying the intricate dance of sovereignty, strategy, and national identity between two regional powers, Iran and the United Arab Emirates. Its strategic location, particularly its proximity to the vital Strait of Hormuz, elevates its status far beyond its modest size, making it a critical asset for any power seeking to influence maritime traffic in one of the world's most crucial waterways.

The dispute over Abu Musa, alongside its sister islands of Greater Tunb and Lesser Tunb, is not merely a territorial squabble; it is a deeply rooted issue with historical, economic, and security implications that resonate across the entire region. Understanding the complexities surrounding Abu Musa requires a journey through its past, an examination of its present role, and a look towards the future of this contested but indispensable island.

The Strategic Jewel of the Persian Gulf

Abu Musa is a small island situated in the Persian Gulf, specifically located at coordinates 52° 25’N, 55° 01’E. It is the southernmost island of Iran in the Persian Gulf, approximately 222 km from Bandar Abbas, 75 km from Bandar Lengeh, and crucially, only 60 km north of Sharjah, one of the emirates that form the United Arab Emirates. A map dated 1891 already showed Abu Musa, indicating its long-standing recognition as a geographical entity in the region.

What makes Abu Musa so invaluable is its strategic position. It allows the power that controls it to significantly influence the maritime traffic that passes through the Strait of Hormuz. This narrow strait is the world's most important oil transit chokepoint, with a substantial portion of the world's seaborne oil passing through it daily. Due to the depth of the sea, oil tankers and big ships often have to pass between Abu Musa and Greater and Lesser Tunbs, making these islands some of the most strategic points in the Persian Gulf. This characteristic has made Abu Musa the point of contention between Iran and the United Arab Emirates, both states actively claiming their sovereignty over the island along with its sister islands of the Greater and Lesser Tunbs.

A Historical Flashpoint: The 1971 Seizure

The current dispute over Abu Musa has its roots firmly planted in the early 1970s, a period of significant geopolitical realignment in the Persian Gulf. The island was under Iranian control until a pivotal moment in late 1971. Iran, then ruled by Shah Mohammad Reza Pahlavi, seized control of Greater Tunb, Lesser Tunb, and Abu Musa on November 30, 1971. This act of military occupation occurred just two days before the formal establishment of the United Arab Emirates (UAE).

The Eve of the UAE's Formation

The timing of the seizure was critical. On November 13, 1971, just weeks before the full occupation, the ruler of Sharjah had reluctantly accepted an interim deal with Iran regarding Abu Musa. This agreement led to the sharing of Abu Musa's offshore oil revenues, a testament to the island's economic value even then. However, this interim arrangement did not prevent the broader military takeover. From the moment Iranian military forces occupied the three islands on November 30, 1971, the United Arab Emirates has consistently and forcefully protested Iran’s illegal occupation of Abu Musa and the Greater and Lesser Tunbs. Since then, Abu Dhabi—particularly the emirates of Ras Al Khaimah and Sharjah—has consistently challenged Iran’s sovereignty claims, accusing Tehran of occupying what it claims as its rightful territory. Iran, however, has administered the islands ever since, maintaining its historical claims to them.

The Uneasy Interim Agreement and Its Collapse

For nearly twenty years following the 1971 events, the UAE and Iran maintained an uneasy interim agreement which led to both countries sharing Abu Musa's offshore oil revenues. This arrangement, while imperfect, provided a fragile framework for managing the dispute, allowing for some level of cooperation despite the underlying sovereignty claims. However, this period of uneasy truce was not destined to last. After talks collapsed to settle the long-standing dispute, the interim agreement effectively dissolved, pushing the islands back into the forefront of regional tensions. The failure of these talks underscored the deep-seated nature of the disagreement, demonstrating that revenue sharing alone could not resolve the fundamental question of who rightfully owns Abu Musa.

The Ongoing Dispute: Claims and Counterclaims

The Persian Gulf islands dispute, specifically concerning Abu Musa, Greater Tunb, and Lesser Tunb, remains a highly sensitive subject in international relations. Both Iran and the United Arab Emirates reaffirm their respective claims with unwavering conviction. Iran asserts its historical sovereignty, viewing the islands as an integral part of its territory that was merely "restored" following the departure of British influence from the region. The UAE, conversely, views Iran's presence as an illegal occupation of its sovereign land, particularly given the islands' historical administration by the emirates of Sharjah and Ras Al Khaimah prior to 1971.

UAE's Consistent Protests

The United Arab Emirates has not wavered in its stance since the initial occupation. Its consistent and forceful protests are a cornerstone of its foreign policy regarding the islands. The UAE frequently raises the issue in international forums, seeking diplomatic solutions and emphasizing the illegality of Iran's continued administration. This persistent advocacy highlights the profound importance the UAE places on reclaiming what it considers its rightful territory, underscoring the dispute's significance beyond mere geographical boundaries to encompass national pride and legal principles.

Modern Maneuvers: GPS Jammers and Territorial Claims

In recent years, the dispute over Abu Musa has taken on new dimensions, reflecting the evolving nature of modern warfare and territorial assertion. Abu Musa’s strategic importance has led to significant investment in its infrastructure and military capabilities by Iran. U.S. officials have reportedly expressed concerns that Iran has placed GPS jammers on Abu Musa. These devices, designed to disrupt Global Positioning System signals, are believed to have interfered with civilian aircraft and ship navigation systems in the vicinity. The potential implications are severe: such interference could possibly cause assets to wander into Iranian air and naval territorial claims, potentially leading to seizures or heightened tensions. These GPS jammers are just the latest addition to an island that has received considerable attention and investment from Iran, further solidifying its control and enhancing its strategic utility in the Persian Gulf.

A Glimpse into the Future: March 2025 Developments

The narrative surrounding Abu Musa is not static; it continues to evolve, with recent statements indicating Iran's ongoing commitment to asserting its sovereignty. While the "Data Kalimat" provided seems to project into the future, referring to events on March 8, 2025, these statements underscore the Iranian perspective on the island's status and its future development.

Architectural Visions and National Identity

On March 8, 2025, Farzana Sadiq, Iran's Minister of Roads and Urban Development, reportedly honored the winners of an architectural competition for the Abu Musa residential complex. This event, if it transpires as described, is highly symbolic. It signifies Iran's long-term vision for the island, treating it not as a contested territory but as an integral part of its national infrastructure and identity. The minister’s statement, "Abu Musa is not just an island, it is also part of the national identity," powerfully encapsulates Iran's deep-seated claim and its efforts to normalize its presence on the island through civilian development and cultural integration. Such initiatives aim to cement Iran's control and present a picture of settled sovereignty to the world.

Unilateral Declarations of Sovereignty

On the same day, the Iranian Prime Minister reportedly officially broke the news of the seizure of the islands of Lesser and Greater Tunbs and the partial occupation of Abu Musa. He stated that the Iranian flag had been hoisted on the tip of Haifa Mountain, the highest point in Abu Musa. He further declared that Iran's sovereignty of the islands was restored following these actions. These statements, whether historical recounting or future projections, highlight Iran's consistent narrative: that its control over these islands is a restoration of historical rights, not an occupation. Such declarations serve to reinforce Iran's position domestically and internationally, despite the ongoing protests from the UAE.

Why Abu Musa Matters: Geopolitical Implications

The islands of Abu Musa, Greater Tunb, and Lesser Tunb are highly valued for their key strategic location in the Strait of Hormuz. Their control offers significant leverage over global energy supplies and maritime trade. For Iran, control of these islands enhances its defensive capabilities and its ability to project power into the Persian Gulf. It serves as a forward operating base, allowing for surveillance and potential interdiction of shipping. For the UAE, reclaiming the islands is a matter of territorial integrity, national pride, and regional security. The ongoing dispute creates a persistent point of friction in the region, impacting diplomatic relations and potentially influencing regional alliances.

Beyond the immediate claimants, the dispute has broader international implications. Major global powers, reliant on the free flow of oil through the Strait of Hormuz, watch the situation closely. Any escalation or disruption in this vital waterway could have ripple effects on the global economy. The presence of GPS jammers on Abu Musa, for instance, is a concern for international shipping and aviation, underscoring the potential for localized disputes to have far-reaching consequences.

The dispute over Abu Musa is a complex tapestry woven from historical claims, strategic imperatives, and national identities. Despite consistent protests from the United Arab Emirates and international calls for peaceful resolution, Iran has maintained its de facto control over the island since 1971. The future of Abu Musa, and indeed the other contested islands, remains uncertain. While diplomatic avenues have been explored, the fundamental disagreement over sovereignty persists.

Moving forward, any resolution would likely require significant diplomatic engagement, possibly involving international mediation, or a shift in the geopolitical landscape of the Persian Gulf. Until such a breakthrough occurs, Abu Musa will continue to stand as a potent symbol of unresolved territorial disputes, a small island with immense strategic weight, constantly reminding the world of the intricate and often tense dynamics that define the region.
