Mapping a New Hemisphere: The Trump Doctrine in Action
As the United States reasserts its influence in Latin America, Secretary of State Marco Rubio's recent diplomatic tour underscores an aggressive push to strengthen ties with right-wing governments across the region. Visiting Colombia, Ecuador, and Peru, Rubio's mission is more than a routine exchange of pleasantries—it is part of a calculated campaign to reshape the hemisphere's geopolitical alignment under the banner of the so-called 'Donroe Doctrine,' named after former President Donald Trump.
"We have a lot of common interest with them, both taking on regional transnational criminal terrorism and also economic engagements," Rubio stated during his visit to Colombia. "It's part of a trend that you're seeing in the Western Hemisphere of alignment with US and US interests."
This statement is not just diplomatic rhetoric—it is a clear signal of intent. With China expanding its trade footprint and asserting regional influence, Washington is racing to secure key allies through economic deals, military cooperation, and ideological alignment. Colombia's new right-wing leadership, under President Abelardo de la Espriella, has eagerly embraced this alignment, signing agreements on critical minerals and civil nuclear cooperation.
Colombia's Turning Point
President de la Espriella, a political newcomer with no prior elected experience, was sworn in in August after a decisive victory that marked the end of left-wing rule in Colombia. His administration's priorities align closely with those of Trump's second term: crackdowns on armed groups, military modernization, and closer U.S. partnerships.
During his meeting with Rubio, de la Espriella emphasized the importance of re-establishing Colombia as the United States' primary partner in hemispheric security—a shift that marks a dramatic departure from the previous administration's more conciliatory approach toward leftist movements and guerrilla groups like the FARC.
This alignment has not gone unnoticed by opposition figures. Ivan Cepeda, a leftist presidential candidate and ally of former President Gustavo Petro, condemned the visit as an "act of surrendering strategic aspects of our sovereignty." The timing of the mineral and energy deals coincided with de la Espriella's announcement to loosen gun restrictions—an echo of Trump's own policies on domestic arms control.
Strategic Vulnerabilities in Ecuador and Peru
Rubio's trip also extended to Ecuador and Peru, countries where recent elections have tilted toward right-wing candidates. In Ecuador, where the administration of Daniel Noboa has pursued a more pro-American stance, the U.S. is keen to solidify trade agreements that could serve as counterweights to Chinese influence.
Similarly, in Peru, Keiko Fujimori's government—despite its controversial history—is being courted by Washington for its alignment with U.S. security priorities. The Trump administration's efforts to expand military cooperation with these governments are part of a broader strategy to assert dominance over the Western Hemisphere, particularly as China grows stronger economically.
Countering China's Influence
The strategic rationale behind Rubio's mission becomes even clearer when viewed in light of China's expanding role in Latin America. In 2009, China signed a free-trade agreement with Peru, and since then, it has become the South American country's top trading partner, surpassing the United States.
Washington sees this as a threat to its economic and strategic interests, especially given China's growing infrastructure investments in the region. By forging closer ties with countries like Colombia, Ecuador, and Peru, the Trump administration aims to create a counterbalance that reinforces American influence in Latin America.
The Cost of Alignment
But this alignment comes at a cost. As countries embrace U.S.-backed policies, they risk alienating segments of their populations who oppose military involvement or economic concessions that favor foreign interests. The decision to loosen gun restrictions in Colombia is just one example of the political and social tensions such moves can create.
In Peru, where Fujimori's controversial legacy includes allegations of human rights violations during her previous tenure, backing her administration raises ethical questions for U.S. policymakers. Yet, with the Trump administration prioritizing stability over democratic norms, these concerns may be outweighed by strategic necessity.
Security as a Weapon
One of the most telling aspects of this strategy is the emphasis on security cooperation. Since returning to office, Trump has authorized military operations in Venezuela and the Caribbean Sea, framing them as necessary responses to drug trafficking and regional instability.
This militarization of U.S. policy is central to the 'Shield of the Americas' initiative—a coalition that brings together right-wing governments to coordinate against transnational crime. The inclusion of Latin American nations within this framework positions the U.S. not only as a trading partner but also as a military power in the region.
What's Next for the Region?
Rubio's tour may have been symbolic, but its implications are far-reaching. As the Trump administration seeks to redefine the balance of power in Latin America, it is doing so with an emphasis on short-term gains over long-term stability. The region now stands at a crossroads—either these right-wing governments will consolidate their power through cooperation with Washington, or they will face increasing internal pressure from opposition movements seeking alternative paths.
For investigative journalists like myself, the real story lies beneath the surface of diplomatic deals and security pacts: the voices of ordinary citizens caught in the crossfire of geopolitical maneuvering. These are the stories that demand attention, not just for their political significance, but for what they reveal about the human cost of strategic alignment.
