Thousands of miles from Bogotá, in the frozen trench lines of eastern Ukraine, Colombian accents have become a familiar sound of war.

Between 1,000 and 2,000 Colombian nationals are currently serving in the ranks of the Armed Forces of Ukraine, according to recent investigations, while as many as 7,000 have passed through the country’s defence forces since Russia’s full-scale invasion in 2022. Their presence has turned Colombia into the single largest source of foreign fighters in Ukraine’s war effort – and estimated 25% – and an unexpected human bridge between two distant conflicts.

What might once have been dismissed as a story of mercenaries and combat-tested veterans has evolved into something far more complex: a shadowy window into the globalization of military labor.

Many of those arriving in Ukraine have witnessed close-hand Colombia’s internal conflict, which for more than six decades has forged one of Latin America’s most experienced armed orces. Trained in counterinsurgency, reconnaissance and irregular warfare, Colombian fighters bring a skillset that has proven adaptable to the grinding, attritional combat of the Donbas.

Ukrainian commanders have taken notice. In some units, Colombians have made up a majority of infantry personnel, valued for their endurance and battlefield discipline. Their roles range from trench warfare to fortification building and increasingly to drone operations, a defining feature of the war.

Yet their journey to the frontlines is rarely driven by ideology.

A steady stream of Colombian soldiers leaves active service each year, often in their late 30s or early 40s. While formal reintegration programmes exist, many veterans struggle to transition into civilian life. Salaries drop sharply after retirement, and the domestic private security sector is saturated. For some, Ukraine offers an economic lifeline.

Combat pay of between US$3,000 and US$5,000 a month – several times the average Colombian wage – is supplemented by signing bonuses and compensation packages for families in the event of death. The contrast is stark enough to turn war into a viable, if perilous, form of employment.

“Colombians understand the risks … yet they still come,” one Ukrainian officer involved in recruitment told local media.

The legal and political framing of these fighters remains contested. In December 2025, the Colombian Congress ratified the United Nations convention against mercenaries, a move backed by the leftist government of President Gustavo Petro.

Under the Convention’s definition, however, most Colombians serving in Ukraine are not considered mercenaries. They are formally integrated into Ukraine’s military structures, receive equal pay to local troops and operate under state command rather than private contracts.

Even so, President Petro has cast the phenomenon as a form of exploitation, warning of the risks faced by citizens drawn into distant war, including the conflict in south Sudan.

Those causes are visible not only in Colombia’s labor market but also in Ukraine’s evolving military structure. As the war has dragged on, Kyiv has reorganized its foreign units, integrating international volunteers into larger brigades to improve coordination and access to heavy weaponry. The shift has further embedded foreign fighters – Colombians among them – into the core of Ukraine’s defensive operations.

The human cost of this integration has been steep. Estimates from the Atlantic Council claim that between 300 and 550 Colombians have been killed in Ukraine since 2022, making them the foreign nationality with the highest number of combat deaths. In Kyiv, Colombian flags now appear among the growing patchwork of memorials to fallen soldiers – a quiet testament to the war’s global reach.

Despite the losses, recruitment has continued. Military analysts say the phenomenon reflects deeper structural failures. Colombia’s decades-long conflict produced a large pool of highly trained personnel, but the transition to civilian life has lagged behind. Skills honed in war have limited application in the formal economy, leaving many veterans in a precarious position.

This dynamic has fed what some researchers describe as a transnational market for military labor, operating in the grey zones of international law. Fighters move between conflicts not necessarily out of allegiance, but out of necessity – carrying their expertise with them.

The implications extend beyond Ukraine. Security analysts warn that the eventual return of battle-hardened veterans, particularly those trained in emerging technologies such as drone warfare, could pose risks if criminal organizations seek to absorb their skills.

For now, however, the flow continues in one direction.

On a recent winter evening in Kyiv, a Colombian veteran reflected on the reality behind the headlines. “Tell Colombians not to come,” he said quietly. “More die than return.”

It is a warning that captures the paradox at the heart of this story: a war that is both distant and deeply connected, drawing in those for whom the frontlines are not just a cause, but a last resort.

In that sense, the presence of Colombians in Ukraine is not an anomaly. It is a signal – of how modern conflicts intersect, and of how the consequences of one war can echo, years later, in another.

U.S. President Donald Trump said on Tuesday there was “no going back” on his goal to bring Greenland under U.S. control, refusing to rule out the use of force and escalating tensions with European allies already bracing for a renewed transatlantic trade dispute.

Trump’s remarks followed a series of social media posts featuring AI-generated images, including one depicting the president standing in Greenland holding a U.S. flag and another showing a map of North America with Canada, Greenland and Venezuela covered by the stars and stripes.

The imagery, shared without official explanation, has fuelled alarm among allies and raised questions about the blurring of political messaging and artificial intelligence at a moment of heightened geopolitical strain.

“As I expressed to everyone, very plainly, Greenland is imperative for National and World Security. There can be no going back — on that, everyone agrees,” Trump said after speaking with NATO Secretary General Mark Rutte.

Greenland, a vast Arctic island rich in minerals and strategically located between North America and Europe, is a self-governing territory of Denmark, a fellow NATO member. Trump’s renewed push to acquire it has revived a proposal he first floated during his previous term, but has now been accompanied by explicit warnings of tariffs and the possible use of force.

European leaders reacted with unease. Danish Prime Minister Mette Frederiksen told parliament in Copenhagen that “the worst may still lie ahead.”

“We can negotiate about everything — security, investments, the economy — but we cannot negotiate our most fundamental values: sovereignty, our country’s identity, our borders and our democracy,” Frederiksen said.

At the World Economic Forum in Davos, European Commission President Ursula von der Leyen urged the bloc to prepare for a more confrontational era.

“The seismic change we are going through today is an opportunity — in fact a necessity — to build a new form of European independence,” she said.

Trade war fears resurface

Trump has threatened steep tariffs on countries he says stand in the way of U.S. interests, including European allies involved in NATO exercises in Greenland. The European Union has warned it could retaliate with tariffs on up to €93 billion ($101 billion) of U.S. imports if trade measures are imposed.

One option under discussion is the EU’s Anti-Coercion Instrument, a powerful tool that could restrict access to public tenders, investment or services, including digital services where U.S. companies hold a surplus.

U.S. Treasury Secretary Scott Bessent sought to calm markets and dismissed fears of an escalating trade war.

“It’s been 48 hours. Sit back, relax,” Bessent told reporters in Davos. “Calm down the hysteria. Take a deep breath.”

Financial markets were less sanguine. U.S. stock index futures slid to one-month lows, global equities fell, and gold prices touched record highs as investors sought safety.

Canada and Venezuela react

The inclusion of Canada and Venezuela in the AI-generated map added to the controversy.

Canada, a close U.S. ally and NATO member, has previously been the subject of Trump’s rhetoric suggesting it could become the “51st state.” Canadian Prime Minister Mark Carney said he was “concerned” by the escalation and warned of the implications for North American and transatlantic security.

Canadian officials said Ottawa has drawn up plans to send a small contingent of soldiers to Greenland to participate in NATO military exercises, pending final approval from Carney. Canada already has aircraft and personnel deployed there as part of a NORAD exercise involving the United States.

Venezuela’s government condemned Trump’s post and called on citizens to share the country’s official map online in what officials described as a symbolic defence of sovereignty.

Russia weighs in

Russia, which has closely watched the growing rift between Washington and Europe, questioned Denmark’s sovereignty over Greenland. Foreign Minister Sergei Lavrov said the island was the result of “colonial conquest,” while denying Moscow had any designs on the territory.

Protesters also took to the streets in several European cities, including Zurich, where demonstrators carried banners opposing Trump’s appearance at Davos and denouncing what they called imperialist policies.

Despite pushback from allies and some members of Congress, Trump has shown no sign of softening his stance, leaving diplomats and markets braced for further escalation as NATO cohesion and global trade relations come under renewed strain.

Colombia’s president, Gustavo Petro, triggered yet another diplomatic rupture in South America on Sunday after denouncing Chile’s president-elect, José Antonio Kast, as a “Nazi,” rejecting the legitimacy of Chile’s democratic choice and sharply diverging from the cautious language typically observed between regional leaders.

Petro’s remarks came within hours of Kast’s decisive victory in Chile’s presidential runoff, in which the conservative candidate secured more than 58 per cent of the vote, defeating hard-left contender Jeannette Jara. Jara conceded promptly, saying that “democracy has spoken loud and clear” and wishing Kast success “for the good of Chile.”

Petro, however, used his social media platform X to frame Kast’s victory as evidence of an advancing wave of fascism in Latin America. “Fascism advances. I will never shake hands with a Nazi or a Nazi’s son, nor will I; they are death in human form,” the Colombian president wrote.

In a retort that called for Chileans to “take care of Neruda’s tomb,” Petro went on to equate Kast’s electoral mandate with the legacy of former dictator Augusto Pinochet. “It’s sad that Pinochet had to impose himself by force, but sadder now is that the people choose their Pinochet: elected or not, they are sons of Hitler and Hitler kills the people,” Petro said, adding that Latin Americans “know how to resist.”

The language marked one of the most explicit attacks by a sitting South American president on a democratically elected counterpart in recent years and raised immediate concerns about the state of Colombia – Chile relations, historically among the region’s most stable.

Kast’s victory completes a broader rightward shift in South American politics, following the election of Javier Milei in Argentina, Daniel Noboa in Ecuador and Nayib Bukele in El Salvador, while Bolivia recently ended nearly two decades of socialist rule with the election of centrist Rodrigo Paz. Petro, the region’s most unhinged left-wing leader, with just eight months remaining in his presidential term, appeared to ignore the potential diplomatic fallout of his remarks.

Within hours of Petro’s statement, US Republican Congressman Carlos Gimenez responded sharply, writing: “This guy (Petro) went too far with the drugs and alcohol. This is the real Gustavo Petro: incoherent, hateful, and schizophrenic.”

Former Colombian president Álvaro Uribe Vélez praised Chile’s electoral process and congratulated Kast, saying the vote had taken place peacefully and reflected citizens’ concerns about security and institutional stability. Uribe described Kast as “a guarantee for democratic institutions” in Chile and the wider region.

Another former president, conservative Andrés Pastrana, issued a sharply worded rebuke of Petro, saying the comments were “inappropriate and irresponsible” and did not represent Colombians nor the long-standing spirit of cooperation between Bogotá and Santiago.

Criticism also came from current lawmakers. Federico Hoyos, a congressman from the department of Antioquia, said Petro had “abandoned his role as head of state” and was acting instead as an “ideological agitator “unwilling to engage with leaders who do not share his views. Andrés Forero, a House representative from the opposition Centro Democrático party, accused Petro of disrespecting the sovereign will of Chilean voters, telling Colombians: “Let’s not fool ourselves, Petro is not a democrat.”

While Petro reviles diplomacy, Kast received public congratulations from international figures across the hemisphere. María Corina Machado, Venezuela’ opposition leader and 2025 Nobel Peace Prize Laureate, praised Chile’s election as “an extraordinary electoral day, an example for many nations of Latin America and the world.”

Addressing Kast directly, Machado wrote: “To the president-elect of Chile, José Antonio Kast, I send my affection and congratulations for the trust he has received. In the name of the Venezuelans, I wish him great success in his government.” She added that Venezuelans hoped to count on Kast’s support “to ensure an orderly transition to democracy in Venezuela” and to help build “a safe, prosperous and free hemisphere.”

Machado’s intervention was notable given her continued persecution by the regime of Nicolás Maduro and her public appearance at the Nobel ceremony last week in Oslo, her first in more than a year.

The United States also welcomed Kast’s victory. Secretary of State Marco Rubio said Washington looked forward to working with the incoming administration “to strengthen regional security and revitalise our trade relationship.”

Kast’s transition team said the president-elect would travel to Argentina this week to meet President Javier Milei, signalling an intention to align closely with like-minded governments in the region.

For Petro, the episode reinforces international perceptions that he has become an anachronism of regional politics — reliant on social-media provocation and historical revisionism.

For all the historical accuracy that seems to elude Petro, membership in Adolf Hitler’s National Socialist Party was not voluntary. While many Germans joined out of conviction, others were pressured or effectively compelled to enrol, particularly to obtain employment, documentation or travel permits. During and immediately after the Second World War, Germans seeking to live or work abroad — including in South America — were often required to disclose or document prior party affiliation to secure passports and legal work status, complicating later assessments of individual responsibility.

Michael Kast, born in 1924 in Thalkirschdorf, Bavaria, emigrated in Chile in 1946. His youngest son, José Antonio Kast (born 1966, Santiago) has repeatedly claimed his father was a Third Reich conscript.

Whether the outburst leads to lasting diplomatic consequences remains uncertain. But it has underscored how electoral change in Latin America is now accompanied not only by sharp policy shifts, but by open rhetorical conflict by a Colombian leader increasingly isolated among his regional peers, except for one ally, Venezuelan dictator Nicolás Maduro.

On Monday afternoon, Chile’s Minister of the Interior, Álvaro Elizalde, confirmed that a Letter of Protest will be sent to President Petro, stating in no uncertain terms that: “A decision has been made to uphold the point of view that has to do with Chilean democracy. Ultimately, the people of Chile decide, and we all have to respect that outcome”.

Hugo Carvajal Barrios, the former Venezuelan intelligence chief known as “El Pollo,” has issued an explosive letter from a U.S. federal prison alleging that Nicolás Maduro’s government systematically used drug trafficking, criminal gangs, espionage networks, and even electoral technology as tools to undermine the United States. The 10-page statement, addressed to “President Trump and the People of the United States,” asserts that Venezuela’s ruling elite operates as a “narco-terrorist organization” with global reach and explicit anti-American intent.

Carvajal, a three-star general who served as Director of Military Intelligence under both Hugo Chávez and Maduro, writes that he is now “sitting in an American prison because I voluntarily plead guilty to the crimes charged against me: a narco-terrorism conspiracy.” He frames the letter not as a political intervention but as an act of accountability: a decision, he says, to reveal “the full truth so that the United States can protect itself from the dangers witnessed for so many years.”

Having broken publicly with the Maduro government in 2017, Carvajal fled Venezuela and was later extradited to the United States. He insists that even as he knew he faced prosecution, he acted “with the strongest conviction to dismantle Maduro’s criminal regime and bring freedom to my country.” Today, he writes, he believes it is essential to warn Americans about “the reality of what the Venezuelan regime truly is and why President Trump’s policies are not only correct, but absolutely necessary to the United States’ national security.”

Maduro and Cabello of Direct “Narco-Terrorism”

Carvajal accuses Maduro and ruling party strongman Diosdado Cabello of transforming the Venezuelan state into a criminal consortium dedicated to drug trafficking. “I personally witnessed how Hugo Chávez’s government became a criminal organization that is now run by Nicolás Maduro, Diosdado Cabello, and other senior regime officials,” he states. The purpose of this network—known internationally as the Cartel de los Soles—was, he claims, “to weaponize drugs against the United States.”

He maintains that narcotrafficking operations facilitated by Venezuela were not the result of corruption or rogue actors. “The drugs that reached your cities through new routes were not accidents… they were deliberate policies coordinated by the Venezuelan regime against the United States,” he writes. According to Carvajal, the strategy “was suggested by the Cuban regime to Chávez in the mid-2000s” and relied on cooperation from the FARC, ELN, Cuban intelligence agencies, and “Hezbollah.” The regime, he adds, supplied “weapons, passports, and impunity” to these groups.

Carvajal devotes a significant portion of the letter to the evolution of the Venezuelan criminal super-gang Tren de Aragua, now considered one of Latin America’s most rapidly expanding transnational crime networks. He claims he personally witnessed its origins inside Venezuelan prisons.

“I was present when decisions were made to organize and weaponize criminal gangs across Venezuela to protect the regime—among them the group known as Tren de Aragua,” he writes. Chávez, he claims, ordered the recruitment of gang leaders “to defend the revolution in exchange for impunity,” while Maduro later expanded the strategy by “exporting criminality and chaos abroad.”

Carvajal alleges that “thousands of members” of the gang were sent out of Venezuela through coordination among the Ministries of Interior and Prisons, the National Guard, and national police forces. He claims the outflow accelerated when “the Biden-Harris open-border policy became widely known,” asserting that Tren de Aragua “seized the opportunity to send these operatives into the United States.”

“They now have obedient, armed personnel on American soil,” he writes, alleging that the gang was ordered to continue “kidnapping, extorting, and killing” as a means of financing itself abroad.

Russian and Cuban Intelligence Behind Spy Networks

Carvajal goes on to detail alleged espionage operations linked to both Russian and Cuban intelligence services. He claims Russian operatives approached Chávez with a plan to tap submarine internet cables linking South America and the Caribbean to the United States – purportedly to intercept U.S. government communications.

He also recounts warning Maduro in 2015 that allowing Russia to build a listening post on La Orchila Island “would one day invite American bombs,” a warning he says was ignored.

According to Carvajal, Venezuela and Cuba also sent operatives into the United States. “For twenty years, the Venezuelan regime sent spies into your country – many are still there, some disguised as members of the Venezuelan opposition,” he writes. Cuban intelligence, he claims, “bragged about having sent thousands of spies over decades, some now career politicians.” Most sensationally, he asserts: “U.S. diplomats and CIA officers were paid to assist Chávez and Maduro… and some remain active to this day.”

Carvajal also revives allegations about the voting-technology company Smartmatic. “The Smartmatic system can be altered—this is a fact,” he writes, claiming he oversaw the placement of the official responsible for information systems at Venezuela’s electoral authority. While he stops short of alleging that U.S. elections were stolen, he asserts that “elections can be rigged with the software and has been used to do so.”

“The Regime Is at War With You”

Carvajal concludes with a sweeping warning to the United States. “Make no mistake about the threat posed by allowing a narco-terrorist organization to roam freely in the Caribbean,” he writes. “The regime I served is not merely hostile—it is at war with you.” He reiterates his support for Trump’s stance on Venezuela, writing: “I absolutely support President Trump’s policy… because it is in self-defense and he is acting based on the truth.”
