Why a Blood Feud Will Test Trump’s Donroe Doctrine

Key Points:

• Flávio Bolsonaro, eldest son of former Brazilian president Jair Bolsonaro, has launched a presidential campaign aiming to unseat Luiz Inácio Lula da Silva, free his father from a 27-year prison sentence, and restore the Bolsonaro family’s political influence.
• The U.S., particularly under Donald Trump’s influence, sees a Bolsonaro restoration as a strategic win to counter China's growing economic influence in Brazil and reinforce American dominance in Latin America, aligning with the "Trump Corollary to the Monroe Doctrine."
• Despite Trump's support, Bolsonaro’s 2022 election loss and subsequent legal troubles—including a coup plot conviction—have weakened the family's position; Lula currently leads or ties with Flávio in recent polls ahead of the October election.
• U.S.-Brazil relations have been tense, with trade imbalances favoring China and recent U.S. tariffs and visa restrictions escalating diplomatic friction, while Lula remains pragmatic about negotiating with the U.S. regardless of administration.
• Experts warn that overt U.S. interference backing Flávio Bolsonaro could backfire politically in Brazil, potentially strengthening Lula’s position and undermining Trump’s ambitions to reassert U.S. influence in the region.
