US eyes control of Diego Garcia via Chagos purchase, says report

The United States is actively pursuing a direct acquisition of the Chagos Islands archipelago from Mauritius, according to recent reporting, marking a significant shift in American strategy toward one of the world's most strategically consequential military installations. The proposed arrangement would effectively transfer sovereignty of Diego Garcia—home to a critical American naval and air force base—directly from Mauritius to Washington, circumventing an existing agreement between the United Kingdom and Mauritius that mandates the UK's handover of the territory by 2036. This development represents a fundamental recalibration of geopolitical arrangements in the Indian Ocean region, one of the world's most contested maritime zones, and carries profound implications for India's strategic positioning, regional security architecture, and the balance of power across South Asia and beyond.

The historical context underlying this potential transaction is essential to understanding its contemporary significance. The Chagos Islands, a British Overseas Territory since 1965, have housed the American military base at Diego Garcia since 1971, following what remains a controversial displacement of the archipelago's original inhabitants, the Chagossians. For decades, this arrangement operated under an implicit understanding that the United States would maintain indefinite access to the facility through its relationship with Britain. However, a 2019 International Court of Justice advisory opinion declared Britain's sovereignty over the islands illegal and non-binding, instructing the UK to relinquish control to Mauritius. Simultaneously, China's expanding naval capabilities and strategic footprint throughout the Indian Ocean have intensified American concerns about maintaining unambiguous control over this Indian Ocean chokepoint. The Trump administration's withdrawal from various international agreements, combined with broader American strategic competition with Beijing, has apparently crystallized Washington's determination to secure Diego Garcia's future through direct ownership rather than rely on shifting diplomatic arrangements or UK intermediation. For Indian policymakers and analysts, this represents a watershed moment in how the world's leading military power envisions its long-term presence in waters that India considers its strategic backyard.

The specifics of Washington's proposal remain partially opaque, but several concrete elements have emerged from reporting and official communications. The arrangement under consideration would involve the United States purchasing the Chagos Islands outright from Mauritius, essentially converting a leasing arrangement into permanent American territory in the Indian Ocean. Diego Garcia itself hosts approximately four thousand American military personnel and contractors, operates as a hub for American military operations spanning from East Africa to Southeast Asia, and provides critical logistics support for naval deployments throughout the Indian Ocean region. The base's strategic value extends beyond mere military positioning; it serves as a crucial waypoint for American surveillance operations, maintains substantial ammunition storage facilities, and functions as a forward operating location for American bombers and reconnaissance aircraft conducting operations across the broader Asia-Pacific theatre. The financial parameters of such a purchase have not been disclosed, though the geopolitical value of securing permanent, unquestioned sovereignty over such a strategically positioned facility would likely command a substantial premium.

For Indian security analysts and policymakers, this potential American move carries immediate and consequential ramifications across multiple strategic dimensions. First, it represents an unambiguous declaration that the United States intends to maintain and deepen its military footprint in the Indian Ocean indefinitely, signaling to India that Washington is not merely a passing security partner but a permanent stakeholder in regional power dynamics. This intensifies the strategic competition India faces in what it has historically considered a zone of privileged influence, particularly given India's own limited military capabilities in the western Indian Ocean compared to its eastern seaboard. Second, the precedent of a major power purchasing sovereign territory to establish permanent military control contradicts the regional norm of respecting the sovereignty and territorial integrity of smaller nations—a principle India itself has traditionally championed. Should the arrangement proceed, it would validate a model of great power assertion that could have destabilizing consequences throughout the Indian Ocean, potentially emboldening other major powers to pursue similar territorial arrangements. Third, India's strategic autonomy in the region becomes more constrained if American military infrastructure achieves permanent, unambiguous territorial grounding that lies beyond the reach of Indian diplomatic leverage or negotiating power. Unlike access agreements that can be terminated or modified, permanent American territory in the Indian Ocean would represent a fixed constraint on India's strategic flexibility.

This development illuminates broader patterns in contemporary great power competition and the crystallization of permanent military positioning strategies in contested maritime zones. The American move reflects a recognition that the era of flexible, informal military presence arrangements may be yielding to a new environment where major powers seek maximum territorial and legal control over strategic locations. China's own strategy of island development and militarization across the South China Sea represents a parallel manifestation of this same impulse, though through different mechanisms. The shift toward purchasing or acquiring territory rather than relying on access agreements mirrors American experiences elsewhere, including its negotiated agreements regarding bases in various allied nations, agreements that have periodically faced political pressure or termination. The Chagos arrangement would represent an attempt to eliminate such vulnerabilities by converting access into outright sovereignty. For India and other regional powers, this trend suggests that the Indian Ocean is entering a phase where the assumption of contested influence and negotiated access is being superseded by attempts at permanent territorial control by external powers. This transformation poses direct questions about the nature of Indian Ocean regionalism and whether traditional frameworks predicated on respect for smaller nations' sovereignty can survive in an environment where major powers prioritize permanent military positioning.

Indian observers and policymakers should monitor several specific developments that will shape how this situation unfolds and what strategic adjustments New Delhi may need to pursue. The diplomatic negotiations between the United States and Mauritius will likely intensify throughout 2024 and 2025, with particular attention warranted to Mauritius's domestic political pressures and any statements from Port Louis regarding negotiations with Washington. The UK's position remains strategically important, as the International Court of Justice opinion and Britain's commitment to transferring sovereignty to Mauritius by 2036 could either facilitate or complicate American acquisition plans. Additionally, China's response to any American purchase will merit close analysis, as Beijing may seek to counter permanent American territorial acquisition through diplomatic recognition of Mauritian claims or through alternative strategic partnerships within the Indian Ocean. India's own response mechanisms—whether through deepened engagement with Mauritius, strategic countermoves in the region, or adjustments to its own military positioning—will demonstrate how New Delhi intends to navigate this evolving security environment. Finally, the positions articulated by other Indian Ocean rim states, particularly Indonesia and Australia, regarding precedents for great power territorial acquisition in the region, will shape whether this arrangement becomes normalized or remains contested within regional security discourse.
