Brazil's Sovereignty Imperative: Why Lula's Advisor Is Talking About Deterrence

Brazil has always punched below its weight in the conversations that matter most. The country that spans 8.5 million square kilometers, borders ten nations, and holds the sixth-largest population on earth has historically approached questions of military capability with a studied ambivalence that its diplomats dress up as "principled non-alignment." That posture survived the Cold War, survived the unipolar moment, and survived two decades of Washington Consensus dominance. But on the evidence of remarks delivered at the International Security Forum 2026, the Lula government is done pretending that goodwill is a substitute for hardware.
Celso Amorim, the former defense minister now serving as special advisor to the presidency, told the gathering in blunt terms that Brazil must "have the capacity for deterrence to defend sovereignty." The phrase carries more freight than its syllables suggest. Deterrence is not a word Latin American officials deploy casually. It implies the possession—or the credible prospect of possession—of capabilities that make the cost of aggression unpalatable to a potential adversary. It is language borrowed from nuclear strategy, adapted by conventional military planners, and deployed most frequently by states that have decided to stop apologizing for their own survival.
The Architecture of a Familiar Silence
Brazil's reluctance to speak openly about deterrence has deep roots. The country developed a quiet nuclear program in the 1970s and 1980s under the military government, then deliberately froze it during the democratization era as a confidence-building measure with neighboring Argentina—a nation with which Brazil had come close to nuclear competition. The Rio de Janeiro protocol of 1991, which established a joint Brazil-Argentina monitoring agency for nuclear materials, became a symbol of South American exceptionalism: a continent where the great-power logic of mutual assured destruction was deemed unnecessary, even alien.
That exceptionalism had a benefactor. For decades, the United States guaranteed the regional security architecture through institutional arrangements—bilateral defense agreements, arms sales, training programs, and the informal hegemony of the Monroe Doctrine's South American extension. South American militaries built around US equipment, trained on US doctrines, and operating within a US-anchored security framework had little incentive to develop the kind of autonomous deterrence thinking that Amorim is now advancing.
The problem with that arrangement was never its effectiveness. The US security umbrella kept the peace between South American states more reliably than any regional institution. The problem was sovereignty—the quiet understanding that the price of that peace was a kind of tutelage. Countries that accept security guarantees from a great power accept that great power's interests as a constraint on their own options. Lula's government appears to have decided that price is too high.
A Multipolar Recalculation
The timing of Amorim's remarks is not accidental. The International Security Forum brings together defense officials, strategists, and analysts at a moment when the global security landscape is undergoing its most significant reconfiguration since 1991. The consolidation of a China-led economic bloc, the steady erosion of US influence in the Global South, and the catastrophic overreach of Western sanctions policy have combined to produce a generation of policymakers in developing nations who regard strategic autonomy not as an ideological preference but as a survival imperative.
Brazil's position within that reconfiguration is unique. Unlike Mexico, which has largely maintained its close US alignment, or Argentina, which has oscillated between alignment and opposition without committing to either, Brazil under Lula has made an explicit bet on what the government calls "autonomous" foreign policy. That means trading with China without accepting Chinese security arrangements, deepening BRICS institutional structures without formally abandoning ties with Western financial institutions, and—as Amorim's remarks make clear—building the defense foundations for a Brazil that can hold its own in a world where the old guarantees no longer hold.
The structural logic is straightforward. In a multipolar world, middle powers that lack independent deterrent capabilities become dependencies of the powers that possess them. They negotiate from weakness, accept unfavorable terms, and find their interests marginalized in the great-power bargains that increasingly determine the shape of the international order. The United States has made this dynamic explicit in its approach to European defense: NATO members are expected to spend 2 percent of GDP on defense not as a gesture of solidarity but because American taxpayers' willingness to underwrite European security is no longer assumed. If Europe must build deterrence capacity on its own, Brazil—which has never enjoyed the formal guarantees that NATO members take for granted—has every reason to conclude that it must do the same.
What Deterrence Actually Means in This Context
It would be a mistake to read Amorim's remarks as a signal that Brazil is moving toward nuclear weapons. The Lula government has maintained consistent public opposition to nuclear proliferation, and Brazil's nuclear program remains under International Atomic Energy Agency monitoring as part of the agreements with Argentina. What Amorim is describing is something more prosaic and, in some ways, more significant: the development of conventional deterrence capabilities robust enough to make Brazil an uncongenial target for any potential aggressor.
That project has already begun. The Brazilian Navy's nuclear submarine program—developed indigenously following the cancellation of a technology transfer agreement with France—represents the most concrete expression of the deterrence logic Amorim articulated. The Álvaro Alberto-class submarines, when operational, will give Brazil a second-strike capability in its littoral waters that no foreign power can neutralize with a first strike. The Air Force's Gripen program, acquired from Sweden rather than the United States, diversifies Brazil's fighter fleet away from the American platforms that dominate Latin American arsenals. These are not nuclear weapons. They are, however, the foundations of a defense posture that no longer depends on the tacit goodwill of a unipolar power.
The harder question is what deterrence means in the non-military dimensions of national power. Brazil's vulnerability to financial sanctions—a tool the United States has deployed with increasing recklessness against countries that challenge its preferences—remains substantial. The Brazilian economy depends on dollar-denominated trade, SWIFT-based financial messaging, and the goodwill of rating agencies that answer to New York and London. A military deterrence capability that deters missiles does nothing to deter the kind of financial strangulation that has brought Venezuela, Iran, and Russia to their knees. Amorim's framing of sovereignty as an integrated project—military, economic, diplomatic—suggests the government understands this. Whether it has the instruments to address the financial dimension is a separate question, and one the sources reviewed for this article do not fully illuminate.
The Stakes for the Hemisphere
If Brazil successfully develops credible deterrence capacity, the implications for South American security architecture are significant. The region has operated for decades on the assumption that Brazilian military weakness was a feature rather than a bug—the country's size alone made it the de facto regional hegemon, and the absence of serious Brazilian military investment meant smaller states could maintain their sovereignty without fear of Brazilian domination. A Brazil that invests seriously in deterrence reshapes that calculus. Neighboring states that have relied on Brazilian restraint as a security guarantee will need to recalibrate their own defense postures.
The more immediate stakes concern the global positioning of a Brazil that is no longer content to be a rule-taker. Countries in the Global South are watching Brazil's experiment in autonomous development closely. If Lula's government can demonstrate that a middle power can maintain strategic independence while navigating between US and Chinese spheres of influence—maintaining trade relationships, avoiding security dependencies, and building the defense foundations for genuine sovereignty—the model will have export value across Africa and Southeast Asia. If Brazil fails—caught between financial vulnerability and insufficient military capability—the lesson will be that strategic autonomy is a luxury only great powers can afford.
What Amorim's remarks make clear is that the Lula government intends to test that proposition rather than accept it as settled. The International Security Forum audience heard a statement of intent, not a detailed strategic plan. The gap between the two will be measured in decades of investment, industrial policy, and diplomatic maneuvering. But the direction is no longer ambiguous. Brazil has decided that sovereignty is not a condition to be preserved through careful management of great-power relationships. It is a capacity to be built—and defended.
