New Name, Familiar Tale
On March 7, 2026, leaders from across Latin America and the Caribbean gathered in Doral, Florida, at the invitation of U.S. President Donald Trump to inaugurate what was presented as a renewed framework for hemispheric security cooperation. Framed in the language of peace, stability, and shared prosperity, the initiative signaled the emergence of a “new” regional security architecture. Yet for Latin America, such moments rarely represent rupture as much as repetition.
Hemispheric security cooperation has historically oscillated between multilateral coordination and asymmetrical dependence, from the 1947 Rio Treaty to more recent counternarcotics partnerships such as the Mérida Initiative and Plan Colombia. The proposed “Shield of the Americas” appears less as a departure from this trajectory than its latest evolution.
Gradually, these attempts at hemispheric cooperation have eroded to give way to coercive action between relevant players in the Americas. We may think of the recent U.S. military incursion in Venezuela in January 2026 or the repeated question mark over American intervention in Mexico posited by President Trump. The game, however, is just as important as the players within it. Much like a prudent player of classic titles such as The Elder Scrolls or any other RPG, it seems the U.S. and its regional allies are investing heavily in defense, both as a principle of their foreign policy toolboxes and as justification for the creation of new multilateral regimes. After all, it is often said that “a good defense is the best offense,” and seemingly this has proven true for allowing Washington to broaden its military operations as far south as Ecuador.
Latin America now finds itself increasingly preoccupied with the offensive capabilities of its northern neighbor, compelled to reconsider how far it is willing to go to defend its people and national vision. Much the same as any prudent, yet astute, RPG player, it increasingly appears that the United States has hidden the sword behind the shield, deploying the language of defense in ways that expand the political legitimacy of intervention across the hemisphere.
The “Return” of Security: A Snake Eating Its Own Tail
The construction of security policy, as discussed by authors linked to security studies, such as Barry Buzan, Ole Wæver, or Thierry Balzacq, has rested upon a government’s ability to define what threats we should be worried about and, as such, the justification to go after them. In truth, Trump’s bid to frame Latin American criminal networks, cartels, gangs, and illegal mass migration as a mortal threat to the peace of mind of U.S. citizens and the nation has come accompanied by mechanisms designed to legitimize action, including multilateral initiatives such as the Shield of the Americas.
Would similar U.S. operations be received the same way if these threats were not collectively recognized as legitimate security concerns? Security theory suggests otherwise. Shared threat narratives allow states to gradually expand the boundary between cooperation and intervention, normalizing actions that might otherwise provoke resistance.
As such, Latin American discussions on security become even more entangled. Like a snake eating its own tail, critics argue the willingness to participate in this new security strategy will come at the cost of a new era of American interventionism, in essence, that most feared by the staunch defenders of Latin American autonomy and anti-American politics in the region.
Is a Shield Truly Ever Without a Sword?
A shield, nevertheless, must be analyzed as a harbinger of retaliation. The United States has made the nature of “defense” quite clear, positioning itself and her hemispheric allies as clear defenders against an onslaught of illegality and criminality. This, in the eyes of the Trump administration, has remained the savage and untamed beast of the Western Hemisphere; a beast that only responds to a language of violence and heavy-handedness. Under such a framing, the region easily finds itself equating military power with social security.
More captivating, however, is the way in which Latin American security policy has echoed this statement and continues to do so. Ecuador’s President Noboa no doubt used this same sentiment when allowing for his country’s security gap to be filled partially by direct military cooperation with the U.S. earlier in March 2026. Likewise, El Salvador’s hard-hitting security reforms ushered in by Bukele followed this same line of action through policies of exception restricting the right to self-defense and high incarceration rates. Even my own country, Mexico, has seen its security policy fall back and forth between open war against drug trafficking networks and political reframing of security under former President López Obrador.
Aside from the purely political nature of security policy, one thing remains constant within these cases; the general population of Latin America is increasingly frustrated by the nature of security and desperate for answers. Across the region, efforts to confront insecurity have often fallen into crisis, making reliance on the United States’ protective “shield” appear increasingly attractive, even as the protection it offers risks expanding Washington’s capacity to intervene once again, whether through its military or political recognition. All the same, the message remains explicit: cooperation is a relationship regulated by Washington for the region, rather than alongside it.
One thing has become clear: a shield, no matter how defensive, is nevertheless a weapon when used in new and creative ways. Across Latin America, worried observers find themselves increasingly on edge as the Shield of the Americas reinforces a growing inertia in regional cooperation. The region now appears to be drifting toward competing visions of hemispheric security, further widening existing fractures between states, as seen in the visible diplomatic tensions between Mexico and Ecuador, Mexico and Peru, and Argentina and Brazil.
Security’s Game: Shields, Swords, and Subordinates
If players are shaped by the games they play, then the hemispheric player operating from Washington appears to do so from a position few can truly challenge. Much like an experienced RPG player, the United States does not need to master every role when its Latin American partners are expected to fill them.
The question, then, is what role these partners are meant to play. The meeting in Doral suggests that they may remain secondary actors within a system largely defined by U.S. security protagonism, shaped by decades of sluggish cooperation and unresolved tensions. In this sense, Latin America risks becoming both the shield invoked to safeguard U.S. interests and the region most affected by its weight.
Supporters of the Shield of the Americas may argue that it offers a concrete response to problems long addressed through softer cooperation. Yet as security once again becomes the region’s dominant political language, it remains unclear whether this new arrangement will lead to genuine partnership through the development of a unified security agenda or to the familiar return of American influence and boots on the ground.
