US Unveils ‘Donroe Doctrine’; Brazil Says Drugs Aren’t the Army’s Job
Defense
Key Facts
—The doctrine. In Cusco on 8 July, the Pentagon’s policy chief announced a Trump Corollary to the Monroe Doctrine, which he nicknamed the “Donroe Doctrine”.
—The three demands. Use force against narco-terrorists, protect critical assets from outside powers, and spend far more on defence.
—The meeting. Washington requested a bilateral with Brazil’s defence minister the same day; it ran 57 minutes and never touched the terrorist designation.
—The answer. José Múcio said fighting drug trafficking inside Brazil belongs to the Justice Ministry, not to him.
—The list. Colby named Venezuela, Nicaragua and Bolivia as governments that enable narco-terrorists. Brazil was not among them.
—The benchmark. He praised Peru’s large F-16 purchase as a model, and criticised countries spending under 1% of GDP on defence.
Washington has given its Latin America policy a name, reviving the Monroe Doctrine and adding President Trump’s initial to it. Hours after announcing it in the Peruvian Andes, it asked Brazil to sign up, and Brazil quietly explained that its army does not do that sort of work.
The setting was the seventeenth Conference of Defense Ministers of the Americas, held this week in Cusco. The speaker was Elbridge Colby, the policy chief of what the Trump administration now calls the Department of War.
What he delivered was not a courtesy address. It was a doctrine, a set of demands, and a warning dressed as an invitation.
What the new Monroe Doctrine actually says
The original doctrine, proclaimed in 1823, told Europe to stay out of the newly independent Americas. It has been read in Latin America ever since as a licence for American intervention rather than a shield against European return.
Colby knows this and argued the opposite case at length. In his prepared remarks he called the region a backwater in American strategy for a generation, and said neglect had turned malign.
He then gave the new policy a name. The Trump Corollary to the Monroe Doctrine, he told the ministers, or more memorably the “Donroe Doctrine”.
Its content is territorial. The United States will protect its homeland and its access to key terrain across the region, and will deny any rival the ability to place forces or threatening capabilities in the hemisphere.
The language about rivals is aimed at China without ever naming it. So is the demand that governments protect what Colby called their critical assets, which in practice means ports, minerals and grids.
Three things Washington wants
First, force. Colby asked governments to dismantle narco-terrorists with effective military and state action, describing partner-led joint operations with American help as force multipliers, and pointing to an American offensive already under way in the region.
He put the case in stark terms. Drugs and the violence around them, he argued, have killed a number of Americans that rivals the country’s costliest wars.
Second, exclusion. Ministers were asked to deny any outside actor the ability to claim or exploit key assets in the hemisphere, in exchange for not being asked to project military power beyond it.
Third, money. He said no country facing narco-terrorist threats should spend less than one percent of its output on defence, and held up European allies now moving toward three and a half percent of core military spending plus a further one and a half.
The sales pitch was explicit. Peru’s large purchase of F-16 fighters, he said, aligns the country with the American defence industry and brings investment to both sides, and it is a model for the hemisphere.
Brazil’s answer was a jurisdictional one
On the margins of the same conference, at Washington’s request, Colby sat down with Brazil’s defence minister, José Múcio Monteiro. According to the Brazilian ministry’s account, the Americans said they were hunting for partners on the continent and saw Brazil as a major potential one.
Múcio expressed interest. Then he explained that combating drug trafficking inside Brazil is the prerogative of the Ministry of Justice and Public Security, and mentioned what the armed forces already do on the borders.
Read plainly, that is a refusal delivered as a point of order. The one thing Colby asked for, a military campaign against the gangs, is the one thing Brazil’s defence minister says is not his to give.
The meeting lasted 57 minutes and did not specifically address the American decision to brand two Brazilian gangs as terrorist organisations. The ministry described the tone as cordial, with a convergence of views.
The omission is the loudest part. That designation took effect on 5 June, and on 1 July Brazil’s foreign ministry warned Congress in writing that it could be used to justify American military force on Brazilian soil.
Colby’s speech does not contradict that fear so much as reframe it. He told the ministers plainly that American military force will help enable, protect and advance operations against narco-terrorists in their countries.
One detail should reassure investors, at least for now. When Colby listed the governments he accused of enabling narco-terrorists, he named Venezuela, Nicaragua and Bolivia, and Brazil was not on the list.
Brazil is being courted rather than accused, which is a materially different position to occupy. Whether it stays there depends on how long a defence minister can keep answering a strategic question with an administrative one.
What is the Trump Corollary to the Monroe Doctrine?
A policy set out in the 2025 National Security Strategy and the 2026 National Defense Strategy under which the United States protects its access to key terrain in the Americas and denies rivals the ability to position forces there. Colby nicknamed it the Donroe Doctrine.
Did Brazil agree to the partnership?
Not in substance. The defence minister expressed interest but said drug enforcement inside Brazil belongs to the Justice Ministry rather than the armed forces.
Why does this matter for foreign investors?
Because it sets the temperature of Brazilian country risk. A courted partner faces sanctions and compliance pressure; an accused one faces something considerably worse.
Frequently Asked Questions
What is the 'Donroe Doctrine'?
It is the nickname Elbridge Colby gave to the Trump Corollary to the Monroe Doctrine, announced on 8 July in Cusco. It calls on Latin American governments to use military force against narco-terrorists, keep critical assets like ports and minerals away from outside powers, and spend more on defence.
What did Brazil's defence minister say when the US asked for help fighting drug traffickers?
José Múcio said that fighting drug trafficking inside Brazil is the job of the Ministry of Justice and Public Security, not the armed forces — effectively turning down the request on procedural grounds. The meeting lasted 57 minutes and did not address the US decision to label two Brazilian gangs as terrorist organisations.
Is Brazil on the US list of countries accused of enabling narco-terrorists?
No — Elbridge Colby named Venezuela, Nicaragua and Bolivia as governments that enable narco-terrorists, and Brazil was not among them. Brazil is currently being courted as a potential partner rather than accused.
