President Trump hosted the Shield of the Americas Summit at Trump National Doral Miami on March 7-8, 2026, gathering leaders from 12 allied Western Hemisphere nations to sign a proclamation launching the Americas Counter-Cartel Coalition — a multinational military cooperation initiative committing signatories to "using lethal military force to destroy the sinister cartels." The summit served simultaneously as the formal debut of Kristi Noem's new role as Special Envoy for the Shield of the Americas, days after Trump fired her as DHS Secretary, and as a venue for Trump to threaten "imminent action" against Cuba and boast about the ongoing Iran war.
Attendees and Exclusions
Leaders from Argentina (Javier Milei), Bolivia, Chile (President-elect Jose Antonio Kast), Costa Rica, the Dominican Republic, Ecuador, El Salvador, Guyana, Honduras, Panama, Paraguay, and Trinidad and Tobago attended — representing roughly one-third of the hemisphere's nations. The gathering was conspicuously limited to conservative, Trump-aligned governments.
Notable absences: Brazil, Mexico, and Colombia — the three largest Latin American economies and historically the most central to hemispheric anti-narcotics cooperation — were not invited. The exclusion of the region's dominant powers undercut the coalition's credibility as a serious security initiative and reinforced critics' characterization of the summit as a political loyalty exercise rather than substantive policy.
The summit effectively replaced the cancelled 10th Summit of the Americas, which had collapsed over the exclusion of leftist-led nations.
Holding a Summit at the President's Own Resort
Trump hosted a gathering of foreign heads of state at a commercial property he personally owns and profits from — Trump National Doral Miami. Foreign governments paying for delegations, hotel rooms, and associated services at a sitting president's business constituted a direct financial benefit to Trump from foreign governments, the precise arrangement the Constitution's Foreign Emoluments Clause was designed to prohibit. The Senate had blocked Democratic resolutions condemning Trump's emoluments violations just four days earlier on March 3. The Doral summit also previewed the resort's hosting of the G-20 summit later in 2026, compounding the scale of the self-dealing.
Key Announcements
Americas Counter-Cartel Coalition: Trump signed a proclamation committing coalition nations to coordinated military operations against drug cartels and transnational criminal organizations. The initiative emphasized the use of lethal military force — including naval strikes on suspected trafficking vessels — rather than the law enforcement, intelligence-sharing, and institution-building approaches that have historically defined hemispheric anti-narcotics cooperation.
Cuba Threats: Trump warned of "imminent action" against Cuba, declaring the island was "at the end of the line" and "in its last moments of life as it was." The threat, delivered while the U.S. was simultaneously waging war against Iran, signaled potential further military escalation in the hemisphere.
Iran War Updates: Trump used the summit to discuss the ongoing U.S.-Israeli military operations in Iran, claiming to have "knocked out" 42 Iranian naval vessels, blending hemispheric security discussions with Middle East war updates in a way that underscored the administration's simultaneous engagement on multiple military fronts.
Noem's New Role
Secretary of State Marco Rubio formally introduced Noem in her new capacity, stating she would work "daily and weekly" with hemispheric leaders on counter-cartel operations. The rapid recycling of a Cabinet secretary fired for incompetence into a newly created diplomatic role — at a summit held at the president's own resort — exemplified the administration's approach to accountability: personnel reshuffling designed to manage political optics rather than address the substantive failures (court contempt proceedings, killed U.S. citizens, inflated deportation statistics, no-bid ad contracts) that prompted the original dismissal.
The "Donroe Doctrine"
Critics characterized the summit as an expression of what observers dubbed the "Donroe Doctrine" — Trump's revival and personalization of the Monroe Doctrine's assertion of U.S. hemispheric dominance. Where the original Monroe Doctrine claimed a sphere of influence against European powers, Trump's version asserted U.S. authority to dictate the internal security policies of allied nations while excluding non-aligned governments from participation, effectively dividing the hemisphere along ideological lines aligned with Trump's personal relationships rather than U.S. strategic interests.
International law experts challenged the legal basis for military strikes on suspected drug-trafficking vessels in international waters, characterizing the administration's approach as "the illegal execution of civilians" operating under the cover of counter-narcotics authority.
