Argentina’s President Javier Milei is signaling a dramatic shift in national security strategy with the appointment of General Carlos Presti as his new defense minister. The move, which included the unprecedented retirement of over half of the country’s serving generals, reflects a growing alignment with conservative, U.S.-backed military figures within the Milei management and raises questions about the increasing role of the armed forces in Argentine politics . The appointment comes as Washington ramps up pressure on Buenos Aires regarding regional policy and as broader geopolitical tensions escalate in the Caribbean.
Argentina’s President Javier Milei has appointed General Carlos Presti as his new defense minister, a move that signals a significant shift toward a more conservative and U.S.-aligned military policy. The appointment follows a sweeping overhaul within the Argentine Army, raising questions about the increasing influence of the military in the country’s political landscape.
Presti’s rise to defense minister was facilitated by Brigadier Jorge Antelo, an associate of businessman Eduardo Eurnekian, who was appointed Secretary of National Strategy early in Milei’s administration. To clear the path for Presti, Milei ordered the retirement of 22 generals – more than half of the 35 then serving – who held seniority over the now-minister of defense. This purge, one of the largest since Argentina’s return to democracy, paved the way for the unprecedented appointment of a general to a ministerial position. Antelo died in July, as Milei faced a period of political instability.
During his two years as head of the Army, Presti cultivated a close relationship with Milei and his sister. The president incorporated the Grenadier Regiment into official ceremonies and was named an honorary grenadier. The Milei siblings also developed trust with military figures like Santiago Ibañez, head of the Casa Militar, who is now being discussed as a potential successor as Army chief.
The appointment of a general as defense minister represents a departure from recent precedent, as former minister Luis Petri was seen as a concession to Patricia Bullrich, a political rival within the ruling coalition. According to sources within the Milei administration, neither Bullrich nor her preferred candidate, Federico Pinedo, had influence over the selection of Presti. The move also appears to be a strategic challenge to Vice President Victoria Villarruel, with the president’s sister playing a key role in appointing a general – the son of a dictator-era repressor – to a position Villarruel had hoped to control.
“The objective is to have a monopoly on the right,” a Milei administration official said, suggesting a desire to consolidate power within La Libertad Avanza. The appointment signals a move away from Milei’s initial disruptive rhetoric toward a more traditional, pro-military right-wing government.
Presti, the son of an infantry regiment commander during the Videla dictatorship, reportedly agreed with the Milei siblings not to request his retirement, a step typically taken by military officials transitioning to civilian roles. Retired General Juan Martin Paleo, a former chief of the Joint General Staff during the Frente de Todos government and recent candidate for a Senate seat, is among those who believe Presti should have retired.
Presti’s decision to remain in active service while holding a political appointment has raised concerns about the politicization of the military and its alignment with the government’s far-right ideology. “He should have retired, it brings politics into the Army,” said an opposition leader.
Presti is not the first military figure to join the Milei administration. General Claudio Pasqualini, former Army chief under President Macri, initially served as deputy defense minister. After Pasqualini’s departure – he is the son-in-law of a convicted human rights criminal – Colonel Marcelo Rozas Garay, a staunch anti-Kirchnerite, assumed the position and is reportedly lobbying to remain in the role under Presti.
The new defense minister is the brother of former Buenos Aires auditor and Macrista legislator Daniel Presti, though those familiar with the family say he does not publicly embrace his father’s past with the same fervor. It remains to be seen whether he will adopt a discourse similar to that of Milani or Villarruel.
An ex-government official suggests Presti’s appointment reflects a broader alignment of Argentina with the United States on defense matters. Presti comes from the liberal wing of the Army and the Infantry branch, an unusual background given that Artillery and Cavalry have historically been more aligned with liberal ideologies. While the Navy has traditionally been anti-Peronist and secular, and the Air Force nationalist and Catholic, the Army encompasses diverse currents. Experts estimate the liberal wing comprises around 30% of the Army, with 40-50% identifying with nationalism and Peronism.
The Presti appointment comes amid increased U.S. pressure on Argentina to align with its foreign policy objectives. According to reports, the presidential office recently requested the Navy to deploy a destroyer near Puerto Rico to support U.S. military operations in the Caribbean, including the bombing of civilian vessels, but the Navy refused citing technical issues. The U.S. embassy also reportedly urged the Milei government to join Washington’s efforts to isolate Venezuela.
Since the beginning of the Milei era, key appointments have gone to individuals with strong ties to the United States. Antelo and Eurnekian also influenced the appointment of Brigadier Xavier Issac as head of the Joint General Staff. Issac, who served as head of the Air Force during the Frente de Todos government, studied at the U.S. Air War College and was an air attaché in Washington. This marked a shift from his predecessor, Paleo, who had been a military attaché in China.
In Washington, Issac worked alongside Navy Admiral Carlos Allievi and Air Force Brigadier Fernando Mengo, who now fall under Presti’s authority. “This alignment is a step backward. The future is with China, as well as the United States, India, the European Union, Turkey… and above all, our neighbors, our first ring,” Paleo told Clarín during the campaign. “I support a balanced relationship. Our dependence, for example, on acquiring F-16 fighter jets in an operation with three countries that do not recognize our sovereignty over the Malvinas Islands – the United States, Great Britain, which occupies them, and Denmark – conditions us. Even the level of devaluation is now managed by Scott Bessent.”
Driven by Secretary of State Marco Rubio and Secretary of War Peter Hegseth, the Trump administration’s offensive in the Caribbean led to the early retirement of the commander of U.S. Southern Command, Alvin Hosley, an African American admiral who visited Ushuaia in April as part of a strategic dispute with China over the continent’s most important bioceanic military corridor.
Hosley is set to retire on December 12, despite having two years remaining in his term. According to Reuters, his departure is linked to tensions with the Secretary of War, as he expressed concerns about the legality and strategic justification for the extrajudicial killings of more than 80 boatmen accused of narco-terrorism. Trump had already dismissed the chairman of the Joint Chiefs of Staff, Charles “CQ” Brown, and the chief of naval operations, Lisa Franchetti, in February.
These developments are occurring within a broader strategic shift: the transfer of leadership for anti-narcotics operations from Southern Command to the Second Marine Expeditionary Force, specializing in rapid interventions, and Trump’s authorization for the CIA to conduct covert operations.
Despite polls showing American opposition to military deployment in the Caribbean, Trump is determined to remove Nicolás Maduro and has a limited time frame to resolve the conflict before the legislative campaign begins, potentially shifting focus away from South America. Trump’s outreach to Lula Da Silva in Brazil has not quelled concerns about military preparations.
The deployment of the USS Gerald Ford, the largest warship in the U.S. fleet, to the Venezuelan coast preceded a dual operation: the State Department’s inclusion of the Cartel de los Soles on its list of terrorist organizations and a demand for the complete closure of Venezuelan airspace. The USS Gerald Ford is leading an operation with ships, fighter jets, and approximately 12,000 personnel.
While Milei projects a successful 2026, he is consolidating support within the local establishment, aligning a bloc of governors, and aiming to secure a minority in the Chamber of Deputies to pass his legislative package in the coming weeks. Meanwhile, layoffs are increasing across various sectors, with hundreds of workers recently losing their jobs at Whirlpool, Essen, Corven, Unicenter, Luxo, Vulcalar, and Yaguar.
Furthermore, reports confirm exclusive reporting by El Destape prior to the October elections, which revealed the worst profitability for banks in the last five years. The Central Bank’s Banking Report now shows further irregularities in family finances and anticipates losses reported by Galicia, Banco Francés, Macro, and Supervielle. The list of those negatively impacted by the Milei model continues to grow.
Economy Minister Luis Caputo, however, remains optimistic, promising Milei an exceptional 2026. Based on what is projected to be the best wheat harvest in over 40 years – 25 million tons, according to the Buenos Aires Grain Exchange – Caputo expects to navigate the summer without problems, intends to return to the markets, and resists accumulating reserves. Privately, the former head of trading at JP Morgan for Latin America is reportedly elated, projecting Chinese-level growth rates and believing the Argentine economy could grow between 6 and 7% in 2026. He also anticipates that the tax amnesty law – the most important for those on the fifth floor – will bring $25 billion into the financial system next year.
In a lengthy article published in The American Prospect, Argentine economist Matías Vernengo considers it unlikely that Milei’s short-term political momentum will last and warns of a new cycle of crisis and default. Titled “Make Argentina Crash Again,” Vernengo argues that Milei’s policies are unsustainable and will lead to collapse, as they did three previous times when the same model was applied – during the dictatorship, with Menem, and with Macri.
The director of the Institute of Public Policy (BIPP) at Bucknell University says Argentina must reduce its dependence on imported capital goods and renegotiate unsustainable debts if it wants to get its external accounts in order. Only then will the country have a basis for sustained recovery that increases the income of the most disadvantaged. Vernengo, who served as a central bank official during the failed Frente de Todos government, claims Milei is doing everything necessary to lead Argentina to a new default, as it faces a mountain of maturities of around $17 billion in 2026. He therefore believes the next government should maintain capital controls and seek a restructuring of the international financial architecture to allow fair access to financing for developing countries. The Trump bailout, which included the loan of U.S. DEGS to allow Argentina to repay the IMF, indicates that this is possible. “Perhaps these funds could be important when Argentina’s next default occurs, which could be near,” he concludes.
