7.4 Is Brazil being isolated?

Evidence for:

1. The Shield of the Americas. - The declaration came on 5 Mar 2026 and the summit on 7 Mar. Brazil was not invited; the Guardian called it "an ideological guest list" that also left out Mexico and Colombia (Colombia joined after its change of government). [V] Guardian; [V] Wikipedia - On 22 Sept the coalition published a list of 24 target organisations, including Brazil's PCC and CV. Al Jazeera: "Brazil and Mexico have not joined". Lula: "Brazil is nobody's back yard". [V] Al Jazeera - So a coalition Brazil does not belong to has named groups operating on Brazilian soil. 2. A bilateral deal that tests Mercosur. The US–Argentina agreement (5 Feb 2026) prompted Brazil to raise its compatibility with the bloc [V-s, Reuters 401]. Valor notes that Decision CMC 32/00 commits members to negotiate jointly, and calls the deal a test that "puts Brazil at a crossroads". [V] Valor International 3. A US military presence on the border. Paraguay's SOFA is in force. ABC Color reports Paraguay's foreign minister denying any tension with Brazil. It also notes that Peña and Lula suspended a planned joint declaration at their Campo Grande meeting, and mentions Paraguay's Shield accession. [V] ABC Color 4. The minerals and AI ring. - Minerals MoUs (4 Feb) went to Argentina, Ecuador, Paraguay and Peru; Chile and Colombia followed later. [V] State; Chile [V-s]; Colombia [V-s] - Pax Silica went to Argentina, Chile, Costa Rica, El Salvador and Panama; the AI Opportunities Declaration also to Paraguay; Peru signed an AI MoU. [V] BNamericas - BNamericas: the US data-center push "has centered on countries more politically aligned with the US administration, such as Colombia, Paraguay, Argentina, Panama and Peru". [V] BNamericas, 13 Oct 2026 5. The sub-national route. Goiás (Caiado) signed a state-level minerals MoU with the US; the federal government objected. [V] v9 §6

Evidence against:

• Brazil attended the 4 Feb Critical Minerals Ministerial in Washington, alongside Mexico, Bolivia and Colombia. It was not shut out of the process, though it signed nothing. [V] State
• The Summit of the Americas was postponed; the exclusions discussed were Cuba, Nicaragua and Venezuela, not Brazil. [V-s] (UPI 403)
• Direct engagement continues. The Magnitsky sanctions were lifted (Dec 2025) [V, v9]. Lula and Trump met in May 2026. Under Lula, the DFC/Pentagon Serra Verde financing went ahead [V, v9].
• Lula pitches Brazil as a data-center host, on the condition that companies produce their own power. After meeting Trump he said Brazil "não vamos gastar dinheiro para criar data center para mandar dados para outros países". [V] Poder360; [V] Mongabay
• The government cloud hedges between blocs. Serpro and Dataprev chose suppliers from both the US and China (7.6). That is not the behaviour of a state being shut out of US technology.
• Local elections drive much of the change. Peru, Colombia, Chile, Honduras and Bolivia all realigned after their own elections, not on a Brazil-specific timetable.

Verdict: Partly supported.

• What is documented: ideologically selected US coalitions and bilateral instruments that leave out Brazil (and Mexico). US policy also reaches Brazil's territory and assets sideways: the Shield's target list, the Paraguay SOFA, Argentina's Mercosur exception, Goiás and the Serra Verde capital. "Going around Brazil" fits these facts.
• What is not documented: no document states isolating Brazil as a goal, and direct US–Brazil engagement continues (minerals ministerial, Lula–Trump meeting).
• What decides it: the 25 Oct runoff. Flávio has publicly promised alignment (CPAC; the Isaac Accords "já em 2027").
