US & Colombia Expand Military Alliance to Fight Regional Drug Cartels

The United States and Colombia are stepping up security cooperation, with Colombia joining a U.S.-led alliance aimed at tackling drug trafficking and organized crime across the Americas.

U.S. Defense Secretary Pete Hegseth welcomed Colombia to the counter-drug alliance during a signing ceremony in Panama, marking a fresh push for closer military ties between the two countries.

The move comes as Colombia’s new government looks to build stronger relations with Washington on counter-narcotics efforts and security.

Hegseth said Colombia had agreed to work with the United States on military operations against terrorist groups and drug-trafficking networks, potentially leading to closer coordination against armed groups operating in the country.

• US and Colombia strengthen military alliance against regional drug cartels
• Colombia joins US-led counter-drug alliance to tackle organized crime
• Washington and Bogotá deepen security cooperation on drug trafficking

Colombia Joins U.S.-Led Counter-Drug Alliance

Colombia has been a key U.S. partner in Latin America’s fight against drug cartels for decades. The two countries have worked together on intelligence sharing, military training and efforts to disrupt cocaine production and trafficking networks.

Hegseth said he discussed possible joint operations with Colombian Defense Minister Jorge Eduardo Mora against groups including the National Liberation Army (ELN) and remnants of the Revolutionary Armed Forces of Colombia. The United States has designated the ELN as a terrorist organization.

Colombia’s entry gives the alliance an important regional partner with long experience in dealing with armed groups and drug cartels. Despite years of efforts to curb trafficking, criminal organizations continue to operate in parts of the country and remain a major security challenge.

The decision also signals a change in Colombia’s relationship with Washington. Under former President Gustavo Petro, disagreements over drug policy and security cooperation created tensions between the two governments. The new administration has taken a more cooperative approach toward the United States.

U.S. Pushes for Stronger Regional Security Cooperation

The agreement comes as the Trump administration takes a tougher approach to drug-trafficking groups in Latin America. Washington has increasingly treated major cartels and criminal organizations as security threats, rather than viewing the issue only as a law-enforcement problem.

The United States has also carried out military strikes against suspected drug-trafficking vessels. Those operations have drawn criticism and raised questions about their legal basis, the use of military force and the protection of civilians.

For Colombia, closer military cooperation could bring greater access to U.S. intelligence, training, equipment and technology. It could also help Colombian forces target trafficking networks and armed groups operating in areas where government control remains limited.

However, deeper military cooperation may also create challenges. Any joint operations involving U.S. and Colombian forces could face scrutiny over national sovereignty, civilian safety and the rules governing the use of force.

Despite these concerns, Colombia’s decision to join the counter-drug alliance marks an important step in its security relationship with the United States. For Washington, Colombia offers an experienced regional partner in the fight against drug trafficking. For Bogotá, closer cooperation could provide additional support as it deals with armed groups and criminal networks at home.

The agreement could also encourage other countries in the region to strengthen cooperation with the United States on organized crime and counter-narcotics. Its success, however, will depend on how the countries balance military action with law enforcement, diplomacy and the need to protect civilians.
