Every April 2, the Malvinas issue returns to the center of the Argentine stage. Behind the memory, the pain, and the historical claim, there is a solid legal framework that supports Argentina's sovereignty claim against the United Kingdom. The first great pillar of the Argentine argument is both historical and legal. Argentina asserts that it inherited the territories of the former Viceroyalty of the Río de la Plata, including the Malvinas Islands, and exercised concrete acts of sovereignty over the archipelago from the first years of independence. The British occupation on January 3, 1833, interrupted this exercise through an act of force in peacetime, expelling Argentine authorities and displacing the settled population. Since 1994, the National Constitution has ratified this sovereignty as legitimate and imprescriptible, defining its recovery by peaceful means as a permanent and non-renounceable goal. The second decisive pillar is the international recognition that a sovereignty dispute exists. In 1965, the United Nations General Assembly approved Resolution 2065, which explicitly recognized the existence of a controversy between Argentina and the United Kingdom and invited both parties to negotiate to find a peaceful solution. This doctrine was reaffirmed later by Resolution 31/49 and successive resolutions of the Special Committee on Decolonization, which continued to demand the resumption of talks between the two parties. For the UN, the problem exists and must be resolved through bilateral negotiation. It is not. This point is central because it dismantles the British idea that the issue is closed. London seeks to invoke the will of the current inhabitants of the islands to support its position. However, the Argentine argument and the UN's interpretation since 1965 go in another direction: Resolution 2065 speaks of the interests of the island population, not their wishes, and that is not a semantic detail. The difference reflects that the case was not framed as a classic decolonization of a subjugated people, but as a sovereignty dispute over a territory whose current population arose after the British occupation. The third legal basis is the discussion on self-determination and territorial integrity. That is why the UN did not apply the principle of self-determination here in the terms it usually does in other colonial processes. What prevails for the Argentine position is the principle of territorial integrity, injured by the 1833 occupation. The fourth basis is projected onto the present and is linked to the sea, the continental shelf, and strategic resources. This is not an empty slogan or an emotional appeal: the Argentine position is based on historical precedents, principles of international law, norms on territorial integrity, UN resolutions, and the geographical and maritime continuity of the national territory. In other words, the international community did not validate the British occupation as a consummated fact, but kept it within a framework of pending decolonization. The geological continuity between the Argentine mainland and the maritime area of the South Atlantic strengthens the argument of the natural prolongation of the territory, recognized by UNCLOS. In 2016, the Commission on the Limits of the Continental Shelf adopted recommendations favorable to the Argentine presentation on extensive areas of the continental margin. That is why, for Argentina, the British exploitation of hydrocarbons, fishing, and other resources in the disputed zone is not only illegitimate but also contrary to the international call not to alter the situation. Thus, the Argentine claim over the Malvinas does not rest on a single piece, but on a coherent framework of history, law, geography, diplomacy, and international legality. The Ministry of Foreign Affairs recalls that the claim was immediate and permanent, and this historical persistence constitutes one of the strongest pillars of the Argentine position. The continuity of diplomatic protest since then is key in any territorial dispute. To this is added a political-legal element of enormous weight: UN Resolution 31/49 urged both parties to refrain from introducing unilateral modifications while the dispute remains open.
