Argentine Southern Strategy: From Joint Communiqué to Power Device

The national address by President Javier Milei operationalized the "state perspective" previously defined by Argentina on August 25. The sequence: he formulated a southern strategic framework whose components reappeared in the joint communiqué of September 3; hours later, he announced how to execute it. It was not just rhetoric about the Malvinas: he formulated a national southern security policy.

Milei announced the acceleration of sanctions under Law 26,659 against unauthorized oil projects; extending them to shareholders, directors, suppliers, and indirect participants; preventing them from operating or contracting in Argentina; expanding the regime to other activities involving natural resources; increasing Defense resources; building an integrated naval base in Tierra del Fuego; reinforcing telecommunications; processing a National Sovereignty Defense Law; and creating a National Security Council that articulates the Ministry of Foreign Affairs, Defense, Intelligence, and Economy. These still require execution, but they already set a direction.

The base seeks to transform Argentina into the main logistical hub of the South Atlantic and strengthen its Antarctic projection. The Council integrates defense, intelligence, foreign policy, economy, resources, infrastructure, and communications. The state perspective acquires institutional architecture.

The Antarctic framework also changes. In the communiqués, Antarctica appeared associated with scientific cooperation, protected areas, patrolling, and the recognition of rights. Milei presented it as a focus of competition for resources. Cooperation remains, but inserted into a competitive strategy. Antarctic rights, the "co-administration" of protected zones, the Combined Naval Antarctic Patrol, and the marine proposal of Domain 1 can operate, in addition to their specific purposes, as instruments of presence, knowledge, and spatial organization. The joint management of ASPA No. 133 Harmony Point does not constitute territorial co-administration; nor does the Domain 1 proposal yet configure a bilaterally administered space.

The decisive expression was "to ensure our preeminence." Its context is the South Atlantic, the Malvinas, and Antarctica. It does not allow attributing a claim over Magallanes to Argentina, but it reveals its aspiration to predominate in the surrounding maritime and logistical system. Recognizing Chilean sovereignty over the Strait and seeking to have logistics, communications, information, defense, and Antarctic projection gravitate towards Tierra del Fuego and Ushuaia are compatible: one concerns the legal title; the other, effective capabilities.

The joint communiqué thus acquires another meaning. Chile reiterated Argentine rights over the Malvinas, South Georgia, South Sandwich, and their maritime spaces; the need to negotiate; and the expectation of avoiding logistical activities that Argentina classifies as illegal. Afterwards, Milei announced sanctions against suppliers and indirect participants, detection and information exchange systems, and the dilemma between intervening in projects linked to the Malvinas or operating in Argentina.

This paragraph may affect port services, ship supply and repair, transport, financing, insurance, and companies related to the islands. It does not oblige Chile to apply Argentine sanctions nor does it define the "efforts" expected. But Argentina expanded the sanctioning perimeter and transformed a diplomatic expectation into a possible test of alignment, with potential impact on Punta Arenas.

Milei did not mention Chile among the like-minded countries whose support he expects. Nor is there evidence that the communiqué prepared the national address. There is, however, functional coincidence: after the presidential visit, Chile reiterated its support and incorporated the logistical reference that the speech later presented as part of the Argentine strategy.

The Malvinas also serve an internal function: they call for unity and focus attention on an external adversary. But this utility does not make the program fictitious. There is also a device of sanctions, intelligence, military infrastructure, telecommunications, pressure on third parties, and southern logistical construction.

The asymmetry is substantive. Chile obtained a reiteration of its sovereignty over the entire Strait, already established by the treaties of 1881 and 1984. Argentina, on the other hand, obtained support for a pending dispute, expectations regarding Chilean logistical conduct, bilateral language on Antarctic rights and spatial cooperation, and a platform to announce capabilities aimed at reinforcing its southern gravitation.

In summary, the joint communiqué did not stop this strategy. Chile obtained, in a declaration, what was already legally settled. Argentina consolidated support and explained how it intends to convert territory, resources, defense, economy, logistics, and Antarctica into effective power. The map remains closed; the competition to organize its connections and condition its flows does not.
