Trump mobilizes Western Hemisphere coalition with aggressive anti-cartel strategy

Donald Trump stood before the leaders and foreign ministers of the Shield of the Americas coalition in New York City on Tuesday and made his case for what he called an existential fight. The cartels plaguing the Western Hemisphere, he said, were the "ISIS of the Western Hemisphere"—a comparison meant to elevate the threat and justify the response. He asked the 15 member nations to formally designate 24 criminal organizations as narco-terrorists and to hit them with what he described as "crushing sanctions."

The list was long and specific. At the top sat Mara Salvatrucha, or MS-13, one of Central America's most entrenched criminal gangs, alongside Tren de Aragua, a Venezuelan organization that has spread into Colombia, Peru, and Chile. The roster also named major Mexican cartels, Colombian armed groups including the National Liberation Army, Brazilian organizations like Primeiro Comando da Capital and Comando Vermelho, and Peru's Shining Path. Twenty-four groups in total, each one a target for asset freezes, visa restrictions, and criminal prosecution.

The coalition's 15 governments issued a joint statement that evening committing to these measures. But the statement, as one observer noted from Bogota, was largely symbolic for now. Each country must follow its own legal procedures. In Colombia, for instance, the government has asked Congress to draft legislation that would allow such designations to proceed. The consequences may not arrive immediately, but the alignment was clear: a coordinated push by the Trump administration to reshape how the region approaches organized crime.

The coalition itself tells a story about alignment and absence. It includes Argentina, Ecuador, and El Salvador—countries whose leaders Trump has publicly praised or endorsed. Colombia and Peru joined after Trump-aligned presidents took office in recent months. But Brazil and Mexico, two of the hemisphere's largest powers, have not joined. Brazilian President Luiz Inacio Lula da Silva, speaking at the United Nations General Assembly where the coalition meeting took place, offered a pointed warning. He bristled at what he called "renewed hegemonic temptations" and declared flatly: "Brazil is nobody's back yard."

This aggressive posture toward the region reflects a broader Trump administration strategy. Since returning to office last year, the administration has designated cartels as foreign terrorist organizations and ordered dozens of military strikes on boats in the Caribbean and eastern Pacific that officials say were carrying drugs bound for the United States. Those strikes have killed more than 223 people. United Nations experts have said the operations violate international law and could constitute crimes against humanity.

The administration's National Security Strategy, released late last year, outlined plans for what it called a revamped Monroe Doctrine—the 19th-century policy that asserted American primacy in the hemisphere and that critics have long associated with decades of US military and political intervention. Trump has also spoken publicly of retaking the Panama Canal and annexing both Greenland and Canada. On Tuesday, he signed an agreement on Greenland that fell short of his stated demand that the island become US territory.

US Secretary of State Marco Rubio, who attended the coalition meeting, praised the "emergence of strong leaders who are committed to the challenge of taking on transnational terrorism." But the gathering also exposed the limits of Trump's regional coalition. The absence of Brazil and Mexico—and Lula's explicit warning about hegemonic ambitions—suggested that even as Trump mobilizes aligned governments, significant resistance and skepticism remain across Latin America about the direction and methods of this renewed American engagement.
