President Javier Milei's participation in the 81st United Nations General Assembly in New York will focus exclusively on the sovereignty dispute over the Malvina Islands, South Georgia and the South Sandwich Islands, and the corresponding maritime and insular spaces . With this mandate, the Argentine Foreign Ministry and the protocol teams at the San Martín Palace are negotiating against the clock with the State Department and the White House to finalize a formal bilateral meeting between Milei and US President Donald Trump , taking advantage of both leaders' presence in Manhattan.

The official schedule already guarantees a first private meeting : both leaders will share the traditional protocol cocktail reception hosted by the US administration for heads of state participating in the UN summit on Tuesday, September 22. However, the Argentine government intends to go beyond the informal greeting and secure a private, one-on-one meeting in which Argentina can present its legal and historical arguments and gauge how far Washington is willing to push the United Kingdom.

Trump's mediation and the Burnham factor

The opportunity to open these negotiations arose from Trump's statements in Dublin, where he broke with historical Anglo-American prudence by describing a potential armed escalation in the South Atlantic as a "potential disaster" and expressing his willingness to intervene to resolve it. His words resonated with alarm in London, not only because they exposed British logistical weaknesses—emphasizing that a deployment would require "weeks on ships" that Westminster could hardly sustain—but also because they revealed cracks in the strategic relationship between the United States and the British Labour government of Andy Burnham , who took office as Prime Minister on July 20 and maintains a strict refusal to discuss sovereignty.

For the Argentine government, Trump's personal stance represents leverage from the international community to force Downing Street to the negotiating table bilaterally under UN Resolution 2065 (XX). The main obstacle remains London's systematic veto, which in recent days reaffirmed the official business guidelines for the islands and dismissed Argentine jurisdiction over the disputed resources.

Negotiation letters: end of abstention and trade reprisals

According to official sources, the action plan that the Casa Rosada seeks to present to Washington includes concrete alternatives to increase the political and economic cost of the colonial occupation:

1.   Shift in multilateral organizations: Request that the United States abandon its traditional stance of abstention or formal neutrality in the votes of the Special Committee on Decolonization (C-24) and in the General Assembly, speaking out in favor of sovereignty dialogue between the parties.

2.   Commercial and criminal sanctions: Exposing the package of measures recently activated on the continent —the Rio Grande precautionary measure that ordered the halting of the Sea Lion works and the Sovereignty Defense Bill that sets fines in barrels and trial in absentia—, opening the door to direct commercial sanctions against British manufactured products and suppliers in the extractive chain.

3.   Exploration of geopolitical guarantees: Evaluate what regional concessions or alignments the White House will demand in exchange for its arbitration, on a playing field where Washington seeks to have London divert its military resources to Europe and release investments in the North Sea.

Although the formal bilateral meeting between Milei and Trump has not yet been officially confirmed on the White House agenda, Argentine diplomacy is focusing its efforts on making it happen between September 21 and 22. The photo and tone of the dialogue in New York will determine whether Trump's intervention in the island dispute establishes a new balance of power vis-à-vis London or whether it fizzles out into a rhetorical maneuver with no effect on the colonial encirclement in the South Atlantic.
