In 1994 I was the lead author of the US National Security Strategy for the Western Hemisphere (in reality, the region below the US-Mexico border and adjacent waters). In that section of the Annual US National Security Strategy Report (which covers the entire globe), my colleagues and I focused on regional democracy promotion and cooperative security arrangements after years of authoritarianism and internal conflicts in Latin America, focusing on civil-military relations, conflict resolution and non-traditional security concerns like environmental degradation, drug production and so-called “human security” issues (e.g. poverty alleviation) that could be mitigated via international military assistance and cooperation programs.
An underlying premise of our work at that time was to try to end the history of US military and grey are/covert (and obsessive anti-communist) interventionism in the region, in particular by deliberately ignoring the 1823 Monroe Doctrine and 1904 Roosevelt Corollary that saw Latin America as the US “backyard” where it played the role of regional policeman via Gunboat Diplomacy and other Big Stick means.
It is therefore with profound alarm that I read that the 2025 US National Security Strategy for the Western Hemisphere explicitly bases itself on the Monroe Doctrine (which is neither a Treaty or sanctioned by international law), and adds a “Trump Corollary” to the Roosevelt Corollary. The Trump Corollary states that the US is the determinant of Latin American fortunes rather than these stemming from the sovereign exercise of a Latin American country’s free will.
Implicit in this strategy is the notion that the US will and can intervene I the internal affairs of Latin American states. It’s interventionism is not guided by support for democracy and/or opposition to autocracy. That is irrelevant to the new US strategic calculus. What matters is the age-old geopolitical concern with having “friendly” and pro-US regimes installed in and foreign competitions pushed out so that the US (or better said, Trump-connected interests) can maximise regional opportunities of an economic and political sort.
The 2025 National Security Strategy for the Western Hemisphere is an outright claim to unilateral US imperialist interventionism. Seen in that light, it frames recent US actions in the region in sharper (and darker) relief and explains its recent meddling in the internal affairs of places like Argentina, Brazil, Honduras, Mexico, El Salvador and Venezuela as component parts of this new (neo) imperialist strategy.
That augers poorly for regional peace and security. The PRC is now the leading trade and investment partner of several LATAM countries and is unwilling to surrender its interests to the US (or better said, Trump-aligned economic interests). It has a satellite tracking facility in Argentine Patagonia and is heavily involved in port management in several countries (including a newly opened container processing port facility and transportation hub in Peru, the largest of its kind in Latin America). It is deeply involved in resource extraction and infrastructure development throughout the region. This is the type of soft power influence that the US used to wield, but which is now being replaced by crony capitalism, election meddling and Gunboat Diplomacy. Although there is much to dislike about its approach, the PRC “does business” with Latin Americans as partners and sovereign equals. The US rattles sabres and extra-judicially kills Latin American civilians under pretexts, regarding its Southern neighbours as nothing more than assorted lawn furniture that can be arranged at will or whimsey.
At some point push may come to shove. The US currently has the strategic advantage over the PRC and other extra-regional competitors, but they may only be temporary as the MAGA administration hollows out the federal government and sows partisan political and social division within US society. In a weird sense, the US could wind up like the USSR at the end of the Cold War: a bloated military machine standing on a fractured society and skewed oligarchical economy where the interests of a connected few prevail over the needs of the many.
Whatever happens, born of ignorance and hubris, this year’s US National Security Strategy is a retrograde turn in its relations with its Latin American neighbours.
