The Shield of the Americas summit at Trump National Doral on March 7 was billed as a security coalition against drug cartels. Read the fine print and it is something considerably more ambitious: a formal restructuring of hemispheric political alignment, built on the premise that Latin American governments will accommodate U.S. military operations in exchange for trade access. The cartels are the pretext. The doctrine is the point.
This Is the Roosevelt Corollary, Updated for 2026
James Monroe declared in 1823 that the Americas were off-limits to European interference. Theodore Roosevelt added a corollary in 1904 that allowed the U.S. to intervene militarily in any hemisphere country experiencing “chronic wrongdoing” — and promptly used it to occupy Cuba, Nicaragua, Haiti, and the Dominican Republic. Trump’s “Shield of the Americas” follows the same structural logic: U.S. security concerns override Latin American sovereignty, and countries that cooperate get favourable treatment, while those that don’t get excluded.
The New York Times reported that Trump assembled leaders from a dozen countries to ask them to help the U.S. military crush armed groups including cartels. But CNBC’s coverage of the event captured the actual terms Trump put on the table: he urged leaders to “use the power of our militaries” and compared the effort to the U.S.-led coalition against ISIS — an analogy that normalises permanent U.S. military coordination on foreign soil as a standing hemispheric arrangement, not a temporary security measure.
The twelve leaders who sat in the room — from Argentina, Bolivia, Chile, Costa Rica, the Dominican Republic, Ecuador, El Salvador, Guyana, Honduras, Panama, Paraguay, and Trinidad and Tobago — have now publicly aligned with the framework. Mexico, Brazil, Colombia, and Venezuela were not invited. That is not a diplomatic oversight. It is a sorting mechanism.
What the Leaders Actually Signed Up For
The summit produced the “Doral Charter” and officially launched the “Americas Counter Cartel Coalition.” But the parallel track — documented by the Washington Trade and Tariff Letter and Americas Quarterly — reveals what attending countries were actually offered: “Agreements on Reciprocal Trade” with performance-based tariff relief, explicitly conditioned on geopolitical alignment with Washington and active pushback against Chinese economic presence in their countries.
El Salvador and Guatemala are the most advanced in these negotiations. The framework uses presidential emergency powers under the International Emergency Economic Powers Act — the same mechanism used for tariffs — giving Trump unilateral authority to extend or withdraw trade benefits based on security cooperation. Countries that host joint U.S. military operations against cartels, cooperate on intelligence sharing, and restrict Chinese infrastructure investment get better trade terms. Countries that don’t, don’t.
This is not a coalition. It is a transaction. Every leader at Doral has now publicly accepted that U.S. military assistance comes with conditions that will be enforced through economic leverage. That bargain will be used against them by their domestic opponents for years.
The Cartel Strategy Itself Has Already Failed Before
Plan Colombia — the closest historical precedent — received $9.94 billion in U.S. aid, 71% of which went to security forces. After fifteen years, coca cultivation had dropped only 18% from 2000 levels. Colombia remained the world’s top cocaine producer. The Government Accountability Office found that the program’s primary drug reduction goals “were not fully met.” Harvard’s International Review concluded bluntly that “a mostly military approach cannot solve complex security problems.”
The New York Times has covered the Trump administration’s counter-cartel approach extensively enough to note what is missing from every press conference: any strategy for reducing U.S. demand, which remains the world’s largest. Operation Southern Spear has carried out more than 40 lethal strikes on alleged drug boats in the Caribbean and Pacific. It has killed 151 people. The cocaine supply has not changed. Supply-side military operations cannot dismantle drug markets while American consumption remains what it is — and Trump has not proposed any demand-side policy whatsoever.
The Doral summit conveniently omitted this detail. The cartel argument gives the doctrine a popular veneer. But you don’t need to build a permanent hemispheric military coalition to reduce drug trafficking — you need drug courts, treatment programmes, and harm reduction policy. What you do need a military coalition for is projecting power, securing basing rights, and keeping China’s infrastructure investment out of strategically important countries.
What This Actually Means
The Shield of the Americas is a formal U.S. security doctrine for the Western Hemisphere, dressed up as a counter-narcotics initiative. The twelve leaders who attended have accepted that U.S. military access and trade access are linked — and that accepting one means accepting both. Mexico, Brazil, and Colombia, representing the hemisphere’s three largest economies outside the United States, declined the invitation. Brazil’s President Lula has already countered by signing a $270 billion resource pact with Canada, Australia, India, the UK, and Japan, settled in non-dollar currencies.
The Monroe Doctrine’s original version kept European powers out of the hemisphere. The Roosevelt Corollary sent the Marines in when governments were insufficiently cooperative. Trump’s version adds economic conditionality: align with Washington, exclude Beijing, host joint operations — or lose your trade preferences. Nobody in any of the twelve countries that attended voted for that arrangement. They voted for their leaders, and their leaders went to Doral.

Background
What is the Monroe Doctrine? Originally articulated by President James Monroe in 1823, the Monroe Doctrine declared that the Western Hemisphere was closed to new European colonisation or interference. It became a cornerstone of U.S. foreign policy. Theodore Roosevelt expanded it in 1904 with his Roosevelt Corollary, which justified U.S. military intervention in Latin American countries experiencing instability — a provision used to occupy several Caribbean nations in the early 20th century.
What is the Shield of the Americas? The Shield of the Americas (formally the “Americas Counter Cartel Coalition”) is a multilateral security framework launched by the Trump administration in March 2026. It brings together ideologically aligned right-wing governments in Latin America and the Caribbean to coordinate military operations against drug cartels and transnational criminal organisations, with U.S. military support including intelligence, logistics, and potentially direct strike capability.
