Within hours of a massive operation of regime change in Venezuela, United States President Donald Trump revelled in his “success”. He posted a photo of Venezuelan President Nicolas Maduro in handcuffs and then addressed the American public.

He praised the military for launching “one of the most stunning, effective and powerful displays of American military might” in US history, allegedly rendering Venezuelan forces “powerless”. He announced that Maduro and his wife would be indicted in New York for “narcoterrorism” and claimed – without evidence – that US operations have reduced maritime drug trafficking by 97 percent.

Trump went further, declaring that the US would “run the country” until an unspecified transition could be arranged, while openly threatening a “second and much larger attack”. Crucially, he framed these claims within a broader assertion of US “domination over the Western Hemisphere”, explicitly invoking the 1823 Monroe Doctrine.

The US military intervention in Venezuela represents something far more dangerous than a single act of aggression. It is the latest manifestation of a centuries-old pattern of US interference that has left Latin America scarred. The regime change operation in Caracas is a clear sign the Trump administration is embracing this old policy of interventionism with renewed fervour. And that bodes ill for the region.

That this attack targeted Maduro’s repressive and corrupt government, which was responsible for the immense suffering of many Venezuelans, makes the situation no less catastrophic. Washington’s long history of supporting brutal dictatorships across the region strips away any pretence of moral authority. Trump himself can hardly claim any moral high ground given that he is himself embroiled in a major political scandal due to his close ties with convicted paedophile Jeffrey Epstein and has maintained unconditional support for Israel’s genocide in Gaza.

The Trump administration’s attack on Venezuela solidifies a catastrophic pattern of violations of international law. If the US can unilaterally launch military strikes against sovereign nations at a whim, then the entire framework of international law becomes meaningless. This tells every nation that might and power trump legality and sovereignty.

For Latin America specifically, the implications are chilling. To understand why this attack reverberates so painfully across the region, one must take a quick look at its history. The US has orchestrated or supported coups and military dictatorships throughout the region with disturbing regularity.

In Guatemala in 1954, the CIA overthrew the democratically elected government of Jacobo Arbenz. In Chile in 1973, the US backed the coup that brought Augusto Pinochet to power and ushered in an era of unchecked political violence. In 1983, the US invaded and occupied the island of Grenada to overthrow its socialist government. In Argentina, Brazil, Uruguay, and throughout Central America, Washington provided training, funding and political cover for military regimes that tortured dissidents and murdered civilians.

The new question now is, if the US carried out regime change in Venezuela so easily, who is next? Colombia’s President Gustavo Petro, who has been at odds with the Trump administration, was quick to react – and is right to be concerned, as in December, Trump threatened an intervention, saying “he’ll be next“. Others in the region are also nervous.

Beyond the looming threat of US intervention, Latin America now also faces the potential regional instability that a regime change in Caracas is likely to create. The political crisis under Maduro had already spilled beyond its borders into neighbouring Colombia and Brazil, where Venezuelans fled poverty and repression. One can only imagine the ripple effect the US-enacted regime change will have.

There are probably many Venezuelans who are celebrating Maduro’s ouster. However, the US intervention directly undermines the political opposition in Venezuela. It would allow the regime, which appears to retain power, to paint all opposition as foreign agents, eroding its legitimacy.

The Venezuelan people deserve democracy, but they have to achieve it themselves with international support, not to have it imposed at gunpoint by a foreign power with a documented history of caring more about resources and geopolitical dominance than human rights.

Latin Americans deserve better than to choose between homegrown authoritarianism and imported violence. What they need is not American bombs but genuine respect for self-determination.

The US has no moral authority to attack Venezuela, regardless of Maduro’s authoritarian nature. Both can be true: Maduro is a dictator who caused immense harm to his people, and US military intervention is an illegal act of aggression that will not resolve the crisis of democracy in Venezuela.

The region’s future must be determined by people themselves, free from the shadow of empire.
