The paradox of emptiness: Strategic islands and contested sovereignty in the Indian Ocean
In Brief
- The strategic value of islands like Diego Garcia lies in their geographic isolation and function as 'unsinkable platforms' for projecting military power, often enhanced by the absence of a civilian population.
- The utility of the British Indian Ocean Territory (BIOT) was created through the controversial, forced removal of the Chagossian people, transforming the territory into a purely securitized space.
- The control of strategic islands is driven by a preemptive geopolitical logic: utilizing them for self-defense and denying their use to adversaries, though this strategy can also stretch resources and invite attack.
- The ongoing struggle over sovereignty and the Chagossians' right to return highlights the persistent ethical and legal challenges inherent in prioritizing military utility over the rights of indigenous populations.

A central paradox of modern geopolitics is that small, remote islands, often perceived as insignificant, can possess immense strategic value in global power dynamics [1, 2]. The very qualities that define their remoteness—geographic isolation and often a lack of indigenous populations or resources—are precisely what can make them indispensable military assets [3]. Stripped of local complexities, these isolated specks of land can be transformed into pure instruments of state power, serving as unsinkable platforms for projecting influence across vast oceanic theaters.
The Chagos Archipelago, and particularly its largest atoll Diego Garcia, serves as a preeminent example of this phenomenon [4, 5]. Centrally located in the Indian Ocean, its modern strategic value was actualized through the controversial removal of its resident population, the Chagossians, in the 1960s and 1970s [6]. This act created a 'blank slate' for the construction of a major joint UK-US military facility, turning the archipelago into a purely strategic space, detached from the typical considerations of governing a populace [7].
This transformation raises fundamental questions about sovereignty, security, and the nature of territorial control in the modern era [8]. The history of Diego Garcia reveals a stark tension between the traditional concept of territory tied to a people and a newer geopolitical reality where depopulated land becomes a strategic commodity. The island's story illustrates how remote archipelagos can become linchpins of global defense, valued not for what they contain, but for the unimpeded military function they can provide [9].
The Strategic Value of Emptiness and Isolation
The ideal strategic island base combines specific geographic features: a sheltered harbor for a large fleet, sufficient isolation to be safe from direct enemy fire, and a landmass small or rugged enough to deter a successful land-based assault . Diego Garcia, a large atoll whose lagoon is almost entirely encircled by a belt of land, fits this archetype with remarkable precision [10]. Its location in the central Indian Ocean provides an unparalleled strategic vantage point, bridging Asia, Africa, and the Middle East .
A crucial, and deeply controversial, element in the creation of such a bastion is the absence of a local population. Official records for the British Indian Ocean Territory baldly state "no indigenous inhabitants," while notes clarify that former agricultural workers, the Chagossians, were forcibly relocated to Mauritius and the Seychelles to make way for the base . This act effectively rendered the islands a blank canvas where all economic and social activity is now solely dedicated to supporting the military installation, with no other industry or agriculture present .
This process transforms the island from a homeland into a pure instrument of state power. Its value lies not in its resources or its people, but in its function as a secure, unsinkable platform for naval and air power—a "bit that restrains the enemy" [11]. The underlying logic suggests that a populated territory presents political and security complexities, whereas an unpopulated one offers uncomplicated control, allowing its occupiers to operate without concerning themselves with local political or religious matters [12, 13].
Islands as Assets and Liabilities in Great Power Competition
From a geopolitical perspective, controlling a strategic island is often as much about denying its use to an adversary as it is about utilizing it for one's own purposes . The historical fear that an unheld island could become a "rendezvous or shelter" for hostile forces has frequently driven powers to preoccupy and fortify such positions [14]. This preemptive logic dictates that key islands cannot be left to other great powers, making their acquisition or control essential for national security [15].
Consequently, remote archipelagos become critical nodes in a global network of defense and power projection. The imperative to create impregnable bases, such as the fortification of Pearl Harbor, arises from the need to secure national interests across vast oceanic distances [16]. These distant outposts are essential for maintaining sea lines of communication and projecting naval strength far from a nation's home shores, without which an empire's fabric and even the subsistence of its people could be threatened [17, 18].
However, this strategy is not without significant risk. Distant insular possessions can also become profound liabilities, stretching a nation's military resources thin [19]. They require a powerful navy for their defense and create new, potentially vulnerable targets for an enemy to strike [20]. The very act of acquiring such territories can invite attack by offering a foe a distant and perhaps less defensible battlefield, forcing a nation to fight on ground where its primary strengths cannot be brought to bear .
The Unsettled Question of Sovereignty
The creation of military islands like Diego Garcia challenges traditional notions of sovereignty. A historical view of power asymmetry suggests that small islands incapable of self-protection are "proper objects for kingdoms to take under their care" [21]. The complete removal of a population to serve the strategic interests of foreign states, however, represents a modern and extreme application of this logic, detaching sovereignty from the consent or presence of the governed .
This manufactured sovereignty is rarely uncontested. Mauritius formally claims the Chagos Archipelago, including Diego Garcia, turning the islands into a subject of international dispute [22, 23]. Furthermore, the displaced Chagossians themselves have pursued legal action against their eviction. They have won significant court rulings that affirmed their UK citizenship and right to repatriation, even as the special military status of the main island was simultaneously upheld, creating a complex and unresolved legal situation .
These legal and political challenges highlight the deep ethical quandaries surrounding these strategic outposts. The Chagossians' decades-long struggle for recognition and the right to return underscores the human cost of a geopolitical strategy that prioritizes depopulated, securitized territory over the rights of its people . It reveals that even when a space is physically emptied for strategic purposes, its political and moral history remains fiercely contested ground, posing a long-term challenge to the legitimacy of its control [24].
The strategic value of small, isolated islands in modern geopolitics is thus a study in paradox. Their perceived emptiness and remoteness, far from rendering them irrelevant, have become their primary assets for military powers seeking secure, uncomplicated forward bases . The case of Diego Garcia exemplifies how a geographic location can be strategically 'activated' through the deliberate removal of its population, creating a purely functional military space that serves as a critical linchpin in a global defense network .
Yet, this utility is purchased at a significant moral and political cost, challenging international norms of sovereignty and generating persistent legal and diplomatic disputes . The enduring struggle of the Chagossian people serves as a powerful reminder that no territory is truly a blank slate. The pursuit of absolute security through the creation of isolated bastions ultimately reveals the complex and often painful intersection of strategic imperatives, international law, and the fundamental right of a people to their homeland .
