Colombia’s presidential election has entered its final phase. The runoff pits Gustavo Petro, a former M-19 guerrilla and leftist senator, against Rodolfo Hernández, a populist billionaire and self-styled anti-corruption candidate. For the defence and security community, this is not merely a domestic political contest. It is a strategic pivot point for the Western Hemisphere with direct implications for US-Colombia counter-narcotics operations, regional stability, and the broader battle against authoritarian creep in Latin America.
Let me be clear: The threat vector is multifaceted. Petro’s platform includes renegotiating the US-Colombia free trade agreement, halting oil exploration, and scaling back the military’s role in internal security. If implemented, these policies would create a vacuum in the Andean Ridge. The FARC dissidents, the ELN, and transnational drug cartels are watching. A Petro victory would be perceived as a green light for resumed territorial expansion. We have seen this playbook before: leftist governments in Bolivia and Venezuela that tolerated criminal narco-states in exchange for political loyalty. The result is a zone of ungoverned space that becomes a launchpad for human trafficking, illicit finance, and eventually, hybrid threats against regional neighbours.
Rodolfo Hernández, by contrast, has pledged to maintain the US alliance, support the oil industry, and continue the security policies of the outgoing Duque administration. His campaign has drawn comparisons to Donald Trump’s 2016 playbook: anti-establishment, heavy use of social media, and a focus on corruption. But here is the intelligence gap: Hernández has no military experience, no clear defence policy, and his inner circle is opaque. We face a binary choice between a known ideological adversary and an unknown quantity. Both introduce uncertainty, but one introduces systemic risk.
The hardware and logistics dimension is equally concerning. Colombia’s armed forces depend heavily on US aid, including Black Hawk helicopters, intelligence-sharing systems, and counter-narcotics training. The Colombian military budget is 3.4% of GDP, but nearly 30% of its equipment is US-sourced. A leftist government could halt or renegotiate these agreements, forcing a pivot to Russian or Chinese suppliers. We have seen this in Venezuela, where Russian-maintained S-300 systems now pose a direct threat to US air operations in the region. A Colombian shift would extend that arc of denial from the Caribbean to the Pacific.
Let us consider the cyber warfare element. The election itself has been marred by disinformation campaigns on WhatsApp and Telegram. We assess with moderate confidence that Russian-linked actors have amplified anti-US narratives and targeted Hernández’s campaign with false claims of voter fraud. This is not ideological. It is a strategic operation to degrade confidence in democratic processes and create pretexts for contested outcomes. If Petro wins, we can expect similar tactics to justify extra-constitutional moves, such as a Constituent Assembly or a court-stacking scheme.
The intelligence failure here is that we have allowed the region to become a secondary theatre. While we fixate on Ukraine and the Indo-Pacific, state actors are quietly embedding in the Americas. Colombia’s runoff is a test case. If the United States and its allies fail to articulate a clear, credible deterrent posture including economic incentives for continued military cooperation and swift sanctions for any deviation, we will lose strategic depth. This is not hyperbole. It is a chess move. And the next move is on 19 June.
In terms of readiness, we must prepare for three scenarios: a Petro victory with rapid policy shifts, a contested election with street violence, or a Hernández win with a slow-burn degradation of institutions. Each requires a different response, but all demand that we treat Colombia not as a foreign policy footnote, but as a forward operating base in the defence of the hemisphere.
The bottom line: The Colombian runoff is a strategic pivot. If we fail to engage now, we will be responding to a crisis later. And by then, the threat vector will have already turned inbound.
