Argentine President Javier Milei endorsed Flávio Bolsonaro for the presidency during the National Convention of the Partido Liberal (PL) in São Paulo on July 25 [1].

This endorsement signals a coordinated effort by right-wing leaders in South America to challenge the influence of left-wing governments in the region. By aligning with the PL, Milei is positioning himself as a key ideological ally in Brazil's upcoming political cycle.

During his address, Milei delivered a harsh critique of socialism and the political left. He referred to socialist policies as "merda socialista" [2]. He further linked the current Brazilian government to socialist failures, stating that such ideologies have harmed the country [3].

Milei explicitly supported the candidacy of Flávio Bolsonaro, asserting that only he possesses the capability to defeat President Lula. "Somente Flávio pode parar Lula," Milei said [4].

The event served as the official launch of Flávio Bolsonaro's presidential candidacy. The convention featured a gathering of right-wing figures, including Milei and Benjamin Netanyahu, to establish a unified front against the current administration [5].

Beyond political endorsements, Milei used the platform to attack the Brazilian judiciary. He directed an insult toward Supreme Court Justice Alexandre de Moraes, calling him "lixo careca" [6]. The Brazilian Supreme Court later criticized the remarks made by the Argentine president following the convention [7].

Milei's presence in São Paulo underscores his desire to export his libertarian-economic model to Brazil. His rhetoric focused on the necessity of a right-wing victory to stop the spread of socialism across the continent [8].

"Somente Flávio pode parar Lula."

Milei's intervention in Brazilian politics represents an escalation of ideological diplomacy in South America. By explicitly backing Flávio Bolsonaro and attacking the Brazilian judiciary, Milei is not merely supporting a candidate but attempting to catalyze a regional right-wing bloc. This approach risks straining diplomatic relations between Argentina and Brazil's judicial institutions, while cementing a strategic alliance between the PL and Milei's administration.
