Why it matters
The South Atlantic concentrates fisheries, hydrocarbons and the gateway to Antarctica, with a NATO-linked base 500 km off the Argentine coast. The capacity to exercise rights there, both legal and material, defines Argentina’s position in the twenty-first century.
The Malvinas question is often presented as a historical wound, and it is one. Reducing it to the memory of 1982 or 1833, however, impoverishes our understanding of it. Seen through a geopolitical lens, the Malvinas are the visible tip of a much broader dispute over control of the South Atlantic, an ocean that the great powers are watching closely again because of its fisheries, its hydrocarbons and its role as the gateway to Antarctica.
An archipelago and an ocean
The United Kingdom has occupied the islands since 1833, when it expelled the Argentine authorities established there. Argentina, which succeeded Spain in sovereignty over the archipelago and protested the dispossession immediately and consistently, never consented to the occupation. The dispute, however, is not limited to land. The 200 miles of the Exclusive Economic Zone and an extended continental shelf contain fishing and hydrocarbon resources of enormous value. Unauthorised fishing at the edge of the EEZ, the so-called mile 201, and offshore exploration are the concrete forms in which the conflict is played out over real resources.
The long diplomatic dispute
In 1965 United Nations General Assembly Resolution 2065 recognised the existence of a sovereignty dispute and invited both States to negotiate, taking into account the interests, not the wishes, of the island population. The distinction is legally decisive. It rules out the application of the principle of self-determination, since the inhabitants are a population transplanted by the occupying power. Later resolutions reiterated the call to negotiate, and the Decolonisation Committee upholds it to this day. In parallel, the technical work of the Commission on the Limits of the Continental Shelf led the United Nations to recognise in 2016 the extension of the Argentine continental shelf, a vast area of seabed and subsoil, while leaving the area around the islands in abeyance because of the dispute.
The militarisation of the South Atlantic
The component that keeps the conflict current is military. The Mount Pleasant base projects British capability, and by extension that of NATO, over an increasingly contested southern ocean. In a world reorganising towards multipolarity, the South Atlantic stops being a margin and becomes a board. Whoever controls its routes and its access to Antarctica gains a weighty position in the global competition for resources and presence.
The national interest
The strength of the Argentine position rests on legal consistency and on the material capacity to exercise rights wherever the law recognises them, far more than on rhetorical emphasis. It is reinforced by the multilateral track and by a sustained claim as a state policy that outlasts governments, by the continental shelf already recognised and, above all, by the effective capacity to control the EEZ, which means monitoring, patrolling and deterring predatory fishing. That capacity links the question to industrial development, with the defence industry centred in Córdoba and port logistics along the Litoral, and it is a reminder that sovereignty rests as much on law as on the means to exercise it.
Conclusion
The Malvinas question belongs to the present as much as to the past. Understanding it as the geopolitics of the South Atlantic, and not only as a grievance, is the condition for defending an interest that is at once maritime, economic and strategic.
