The transformation is most visible in the aftermath of Nicolás Maduro’s arrest in Venezuela, which has sent shockwaves through remaining leftist governments and emboldened opposition movements across the continent. Intelligence analysts are now betting that the so-called pink tide won’t gradually recede but will collapse entirely under the weight of its own contradictions by year’s end.
The shift is both externally driven by the Trump administration’s openly interventionist approach and internally, as socialist policies fail to deliver economic results that maintain electoral support.
Former Revolutionaries Reject the Model
Perhaps nowhere is the ideological fracture more striking than in Colombia.
Enrique Serrano, a Colombian political analyst with over 40 years of studying U.S.-Latin American relations, tells The Cipher Brief that the left’s failure stems from a fundamental misreading of its own base.
“Those left-wing politicians in Latin America didn’t expect a rise within the middle part of our society,” he explains. “The middle class — they are drifting towards the right because they need more money. It’s more important for them that there’s no governmental regulation on income, for example, on economic opportunities.”
The shift is measurable across the region. In Colombia, Serrano notes that approximately 60 percent of the population now identifies as middle class. Yet, Petro’s policies have targeted people experiencing poverty and the working class, who “normally don’t go vote.”
In Argentina, middle-class frustration with inflation exceeding 200 percent annually drove voters to embrace libertarian Javier Milei’s radical free-market platform. Chile’s 2023 rejection of a progressive constitution — despite electing leftist Gabriel Boric in 2021 — reflected similar middle-class concerns about economic stability over ideological purity. Even in Brazil, Lula’s narrow 2022 victory margin has eroded as middle-class voters increasingly question his economic management and tolerance of regional autocrats.
The shift represents a stunning reversal for a region that seemed firmly in socialism’s grip just three years ago.
“I have never noticed such a strong and such a direct impact from the US on Latin America like it is happening today,” Serrano says. “I see that also in the context of Marco Rubio. There is a strong change compared to the last 40 years right now.”
President Gustavo Petro’s administration is hemorrhaging support not just from centrists but from within the left itself. His approval rating has plummeted to 35.7 percent with a 53.7 percent disapproval rating according to January 2026 polling, down from 48 percent approval when he took office in August 2022. Even within his own Pacto Histórico coalition, internal divisions have emerged as 72 percent of Colombians now believe the country is heading in the wrong direction.
Despite winning the presidency in 2022 as Colombia’s first leftist leader, Petro now commands only his core 30 percent base — approximately six to seven million voters out of 24 to 25 million — as the country approaches crucial May elections.
“The left failed because they’re offering politics towards really the poor, or the workers on the street,” Serrano says. “But those people normally don’t go vote. The ones who put in the most votes are the middle class, and the left is not reaching out towards the middle class.”
The electoral math bears this out. In Colombia’s 2022 presidential election, Petro won with just 50.4 percent in the runoff, the narrowest margin in recent history, despite mobilizing his base. Colombia’s economy grew just 1.6 percent in 2025, well below regional averages, while its healthcare reforms triggered a system collapse, and its security policies failed to stem rising crime rates.
Similar patterns are visible across the region. In Chile, despite electing leftist Gabriel Boric in 2021, voters decisively rejected his proposed progressive constitution in 2023 by nearly 62 percent, with middle-class neighborhoods leading the opposition. Despite his narrow victory in Brazil’s 2022 election by less than two percentage points, Lula’s approval rating has fluctuated significantly.
After hitting a historic low of 24 percent in February 2025—the lowest across all his administrations — his numbers have since rebounded to 48 percent by January 2026. However, 45 percent of Brazilians say they would never vote for him. His recovery came largely through confrontations with Trump rather than domestic policy successes. At the same time, critics cite his tolerance for regional autocrats like Maduro and economic challenges, including food inflation, that particularly hurt his traditional support base among the poor.
A senior U.S. intelligence official, speaking to The Cipher Brief on background, confirmed that internal assessments show socialist governments across the region facing simultaneous crises of legitimacy, economics, and security.
Colombia’s Dual Crises
President Petro’s tenure has been marked by contradictions that illuminate broader challenges facing Latin American socialism. While maintaining popularity among his leftist base, his administration has struggled with governance basics while simultaneously drawing scrutiny for connections between leftist politics and transnational criminal networks — a pattern that has implications far beyond Colombia’s borders for U.S. counternarcotics and security efforts.
Petro’s governance has been plagued by scandals that blur the line between politics and criminality. The Trump administration sanctioned Petro in October 2025, accusing him of allowing drug cartels to “flourish” while cocaine production in Colombia reached its highest levels in decades. Though Petro denies direct cartel ties and the New York Times found no evidence of personal criminal connections, his son was arrested in a money laundering scandal involving campaign financing. At the same time, two former cabinet ministers were jailed in December 2025 for orchestrating a vote-buying scheme that diverted public contracts in exchange for legislative support.
It goes beyond Colombia.
The Maduro regime became a haven for Iranian operatives and Hezbollah networks before his arrest, while the Ortega regime in Nicaragua has been accused of providing sanctuary to anti-American forces. This visible fusion of leftist governance with criminal organizations represents a marked shift from previous decades, when corruption, while present, remained more discreet, complicating U.S. counternarcotics efforts and security cooperation throughout the hemisphere.
Petro’s relationship with Washington has been equally contradictory. After months of public confrontations with the Trump administration over deportation flights and trade threats, Petro abruptly shifted course following a phone call with President Trump earlier this year.
On January 26, 2025, Petro blocked two U.S. military aircraft carrying 160 Colombian deportees from landing, declaring he would “never allow Colombians to be brought back in handcuffs.” Within hours, Trump threatened 25 percent tariffs on all Colombian imports, rising to 50 percent within a week, plus visa sanctions on government officials and enhanced customs inspections.
Petro initially responded defiantly, announcing retaliatory tariffs and posting on social media that “your blockade doesn’t scare me.” Yet by that evening, after the White House threat to Colombia’s $28.7 billion in annual exports to the U.S., Petro capitulated completely, agreeing to “all of President Trump’s terms, including the unrestricted acceptance of all illegal aliens from Colombia returned from the United States, including on U.S. military aircraft, without limitation or delay.”
Following the cordial phone call in January, Trump invited Petro to Washington for a February meeting that “dramatically reversed their war of words.” The sudden rapprochement caught observers off guard. The about-face revealed the extent to which even vocal anti-American leftist leaders now recognize their vulnerability to U.S. economic pressure.
Electoral Reckoning Approaches
Colombia’s May elections are shaping up as a referendum on the country’s leftward turn. Iván Cepeda, Petro’s preferred successor, enters the race with heavy ideological baggage. Following years of economic and social volatility, the electorate has become increasingly wary of socialist rhetoric. The 63-year-old senator is the son of a murdered communist party leader, studied philosophy in Bulgaria during the communist era, and has been active in various leftist movements, including the Communist Party and groups linked to former FARC guerrillas.
Cepeda faces political outsider Abelardo de la Espriella, a self-made criminal defense lawyer and businessman. The 47-year-old from Montería built a lucrative law practice defending celebrities and high-profile clients, including the recently arrested Alex Saab, before launching his presidential bid. Recent polling shows de la Espriella leading with 28 percent support versus Cepeda’s 26.5 percent, with the gap widening to 9.3 percentage points in a hypothetical runoff.
“Politics needs fewer politicians and more businessmen,” de la Espriella told Reuters, promising 6-7 percent annual economic growth through infrastructure investment and deregulation — a stark contrast to Colombia’s anemic 1.6 percent growth under Petro’s socialist policies.
The Colombian race also reflects broader regional trends. According to some experts, the pink tide’s momentum has reversed so dramatically that remaining leftist leaders now find themselves isolated.
“Gustavo Petro is facing a situation where he’s standing almost alone right now because the rest of the region turned to the right already, like Chile, like Argentina,” Serrano says. “So he’s only having two strong allies still in the region, which would be Lula and Claudia Sheinbaum in Mexico.”
Even those alliances are crumbling.
“Petro only has as allies Lula, who is almost about to fall, and Sheinbaum, who is alone,” Serrano continues.
The rightward shift in recent years has brought leaders like El Salvador’s Nayib Bukele, Argentina’s Javier Milei, and Ecuador’s Daniel Noboa to power, creating a new conservative bloc that has welcomed closer ties with the Trump administration and rejected the socialist solidarity that characterized the previous decade.
Existential Threats Beyond the Mainland
The potential socialist collapse extends beyond South America. Cuba, long considered impervious to change despite six decades of communist rule, now faces its most serious existential crisis.
Washington’s regional focus has shifted from Cold War ideological containment to pragmatic strategic interests; a calculation that explains the administration’s surgical approach to Venezuela while largely ignoring Havana.
Cuba, which has maintained communist rule since Fidel Castro’s 1959 revolution, now faces its most serious existential crisis in over six decades. The island’s economy has contracted sharply, with GDP shrinking and basic services collapsing. Prolonged blackouts affecting millions have become routine as the electrical grid repeatedly fails, while severe food shortages have driven unprecedented waves of emigration.
“Their situation is worse (than Venezuela) because they don’t have natural resources,” Serrano underscores. “They don’t have electricity. They can’t produce electricity on their own, and they don’t have food either. So it’s very unlikely that the government in Cuba might survive this year.”
The island’s energy infrastructure has repeatedly failed, leaving millions without electricity for days at a time, while food shortages have driven unprecedented emigration.
Nicaragua faces similar pressures under Daniel Ortega’s increasingly isolated regime. Ortega has ruled since 2007, consolidating power through mass arrests of opposition leaders, shuttering of independent media, and the expulsion of international observers. The regime’s systematic repression has driven over 300,000 Nicaraguans into exile while leaving the country economically stagnant and diplomatically isolated.
“Those authoritarian governments like Venezuela, Nicaragua and Cuba — what they in real life try to do is just to gain time,” Serrano told The Cipher Brief. “They will disappear earlier or later. It’s just they try to get as much time as possible.”
The convergence of economic failure, political repression, and technological change has created conditions fundamentally different from those that allowed previous generations of authoritarian leftist governments to survive for decades.
Technology Accelerates Socialist Decline
In addition, the digital revolution has destroyed the old-school socialist playbook. As mobile technology has expanded across Latin America, governments have lost their most powerful tool: the narrative. U.S. analysts are currently monitoring how this decentralized flow of information, from protest coordination on encrypted apps to real-time leaks of government corruption, is creating a level of accountability that previous generations of leftist leaders never had to face.
Beyond Cuba and Nicaragua, other left-wing regimes recently faced Trump administration scrutiny. In Honduras, leftist president Xiomara Castro was defeated in the November 2025 elections by Trump-backed conservative Nasry Asfura, who took office in January 2026. Castro’s tenure had raised concerns in Washington about her government’s ties to China and open support for authoritarian regimes, including Venezuela and Nicaragua.
U.S. Strategic Implications
With the collapse of the pink tide, Washington faces both opportunities and risks. The shift away from socialism aligns with U.S. interests, but it also creates vulnerabilities that adversaries may exploit. The penetration of organized crime, particularly groups with ties to Iran and Hezbollah, remains a persistent concern.
Mauricio Baquero, Venezuelan opposition organizer and María Corina Machado’s representative for Latin America, tells The Cipher Brief that authoritarian governments’ tolerance of malign foreign actors poses direct threats to U.S. security.
“The Nicholas Maduro government allowed Hezbollah and Iran officials to be in Venezuela,” he explains. “So that’s obviously a source of insecurity in the whole region.”
Luis Bustos, spokesperson for Venezuelan opposition party Primero Justicia, tells The Cipher Brief that removing foreign actors remains a critical challenge even after Maduro’s arrest. Regarding whether interim president Delcy Rodríguez continues tolerating Hezbollah’s presence in Venezuela, he explains that “it’s not possible to get them out of the country really quickly.” his reality, he explains, underscores why “it’s not recommendable” to rush elections.
“We need a time of transition where we make sure that all those influences from abroad, among them, Hezbollah, for example, will leave the country,” he says.
Since socialist governments have provided sanctuary to anti-American actors, including Iranian operatives, Russian intelligence services, and Chinese surveillance networks, Washington has made the pink tide’s recession a national security priority, rather than a matter of ideological preference.
According to Serrano and others, the Trump administration’s aggressive approach, particularly in Venezuela, has accelerated changes that might otherwise have taken years.
As several Latin American nations drift rightward, the question is no longer whether the pink tide will recede, but whether any socialist government can survive the decade ahead without dramatic policy reversals that abandon the model’s core premises.
“Not over, but it’s failing,” Serrano adds. “And the region needs to examine why.”
