Nuclear energy, defense and hemispheric power
Asunción / Los Angeles — June 2026
The agreements between the United States and Paraguay mark more than a bilateral diplomatic advance. They reveal a broader strategic movement: Washington is rebuilding influence in Latin America through energy, defense cooperation and institutional alignment.
After the meeting between President Santiago Peña and U.S. Secretary of State Marco Rubio in Los Angeles, Paraguay announced agreements focused on civil nuclear energy and security cooperation. The language is technical, but the geopolitical message is direct. Paraguay is positioning itself as one of Washington’s closest partners in South America.
Civil nuclear cooperation is especially significant. Paraguay already has abundant hydroelectric capacity through Itaipú and Yacyretá, but nuclear energy introduces another layer: technological modernization, energy diversification and access to high-value strategic expertise. For the United States, this is also a way to anchor standards, suppliers and influence before other global powers occupy that space.
The defense component is equally important. Earlier this year, Paraguayan lawmakers approved a Status of Forces Agreement allowing the temporary presence of U.S. military and civilian personnel for training, joint exercises and humanitarian missions. Supporters describe it as a tool against organized crime and transnational threats; critics warn of sovereignty risks and expanded legal protections for U.S. personnel.
The Peña government appears willing to accept that trade-off. Its foreign policy has increasingly favored close alignment with Washington, including security, investment and diplomatic coordination. In a region where China, Russia and Iran have sought varying degrees of influence, Paraguay’s position becomes strategically useful for the United States.
Paraguay is not a regional giant, but it has geographic value. Located at the heart of South America, bordering Brazil, Argentina and Bolivia, it occupies a corridor relevant to logistics, agriculture, energy and security. In strategic terms, influence in Paraguay offers Washington a foothold in the continental interior, not only along the Pacific or Atlantic edges.
The nuclear agreement should not be read as a sudden move toward weapons or military escalation. Its stated focus is civil and peaceful use. But civil nuclear frameworks still matter geopolitically because they create long-term dependencies: training, regulation, technology transfer, safety standards, fuel chains and institutional partnerships.
That is why these agreements are part of a wider pattern. The United States is no longer relying only on speeches about democracy or free markets. It is using infrastructure, security cooperation and advanced technology as instruments of hemispheric positioning. Paraguay is becoming one of the clearest examples of that shift.
For Latin America, the question is not whether cooperation with Washington is useful. It often is. The question is whether countries can convert that cooperation into national capacity rather than dependency. Nuclear energy and defense agreements require transparency, institutional oversight and clear public accountability.
Paraguay now faces that test. If managed with rigor, the agreements could strengthen energy planning, technical education, security cooperation and international credibility. If handled as opaque geopolitical alignment, they may deepen domestic suspicion and revive old debates about sovereignty.
The strategic importance of this moment lies in its architecture. Energy and defense are no longer separate files. They are converging into a single language of power. Through Paraguay, Washington is signaling that the contest for influence in Latin America will be fought not only through elections or ideology, but through technology, security and infrastructure.
La verdad no grita: estructura el poder.
