Background The grouping that became the Shield of the Americas emerged from political lobbying of the incoming second Trump administration after Donald Trump's victory in the
2024 United States presidential election. Through lobbying, especially of Argentine president
Javier Milei, Ecuadorian president
Daniel Noboa, and El Salvadoran president
Nayib Bukele seeking to secure political, financial, military support from the incoming administration. Other governments engaged in such efforts included Colombia, the Dominican Republic, Guyana, Haiti, Honduras, and Panama. All three would be among several heads of state at
Donald Trump's second presidential inauguration on January 20, 2025. Leandro Morgenfeld, coordinator for the study group on the U.S. of the
Latin American Council of Social Sciences, argues that the alignment of Bukele, Milei, Noboa, and Peña with U.S. president Donald Trump is due to the latter's revival of the
Monroe Doctrine in foreign policy. He explains that governments in the Americas that don't align with the United States are subject to threats, while those that are aligned become subject to American
neocolonialism. The grouping is also informed by ideological alignment, priorities in finance, and securing political support from the United States, amidst international criticism.
U.S. President Trump's second administration was critical of Bukele and Milei securing loans from the
IMF,
World Bank and
Inter-American Development Bank through the U.S.’s vote share on such institutions. Ivan Briscoe, a senior policy director from the
International Crisis Group, argued on
NPR that Trump’s foreign policy toward
Latin America is intended to build a coalition ideologically aligned with his administration. Those politically or militarily opposed to his administration’s actions in the Americas, even traditional allies such as
Brazil and
Colombia, have faced travel restrictions and
sanctions from the United States. Most of the
MAGA movement see the Americas as a
territorial extension of the
continental United States. Concerning the region, the
2025 National Security Strategy says the United States will “will reward and encourage the region’s governments, political parties, andmovements broadly aligned with our principles and strategy.”
Formation On March 7, 2026, President Trump signed a proclamation launching the Shield of the Americas initiative, establishing an Americas Counter-Cartel Coalition. The signing took place at the Shield of the Americas Summit at
Trump National Doral Miami. The proclamation commits participating nations to coordinate military and law enforcement efforts to combat transnational criminal organizations, particularly drug cartels. Attendees included Secretary of State
Marco Rubio, Secretary of Defense
Pete Hegseth, Secretary of Homeland Security
Kristi Noem, Treasury Secretary
