US-Argentina Naval Partnership Strengthens South Atlantic Presence Amid Falklands Claims

President Milei authorized the USS Nimitz and USS Gridley to enter Argentina's waters for PASSEX 2026 joint exercises, marking a bold US-Argentina naval partnership in the South Atlantic. As Milei reaffirms the Falklands are Argentine, UK leaders push back, while a leaked Pentagon email hints at shifts.

President Milei signed Decree 264/2026 authorizing the USS Nimitz aircraft carrier and USS Gridley destroyer to enter Argentina’s Exclusive Economic Zone for joint naval exercises PASSEX 2026 and Daga Atlántica.

The carrier is now operating in Argentine waters as part of the pre-planned U.S. Southern Seas 2026 deployment.

Milei has strongly reaffirmed that the Falkland Islands “were, are, and will always be Argentine.”

A leaked Pentagon email discussed reviewing long-standing U.S. diplomatic positions on the dispute.

UK leaders Keir Starmer and Kemi Badenoch have firmly restated British sovereignty and the islanders’ right to self-determination.

This deployment demonstrates American naval presence and deterrence in the South Atlantic. It occurs amid Milei’s repeated public emphasis on advancing Argentina’s claim to the Falkland Islands judiciously.

America First policy favors strong, aligned partners who understand strength and sovereignty in a contested region.

Strength and clarity deter conflict. ⚓🛡️🇺🇸 #AmericaFirst #Geopolitics #FalklandIslands
