El Salvador deployed more than 2,000 troops to Haiti last week in a significant unilateral military operation aimed at combating gang violence in the Caribbean nation, a move endorsed by former U.S. President Donald Trump. The deployment, one of the largest bilateral military engagements in Haiti in decades, comes amid escalating insecurity in Haiti, where gangs control large parts of Port-au-Prince and have contributed to a surge in violence that has claimed thousands of lives this year.

The decision follows the October 18 kidnapping of four Salvadoran soldiers serving with a United Nations-backed Gang Suppression Force. President Nayib Bukele of El Salvador announced the deployment on the social media platform X, stating that the operation was intended to “teach the gangs a lesson” but stressed it was not an invasion or an action against the Haitian people. Bukele framed the mission as an extension of his tough anti-gang tactics that have significantly reduced crime in El Salvador, a country that once had one of the highest homicide rates globally. He claimed that El Salvador is covering up to 90 percent of the mission’s costs, while U.S. Southern Command confirmed that the Trump administration provided at least one flight supporting troop transportation.

The arrival of Salvadoran forces adds complexity to Haiti’s already crowded and fragmented security landscape. In addition to the Salvadoran troops, Haiti hosts a United Nations-led Gang Suppression Force that has struggled to reach its planned strength of 5,500 personnel since it was authorized in 2023. This international mission, which includes soldiers from Chad, Mongolia, and other countries, operates under strict rules of engagement and has been criticized as slow and ineffective. The Salvadoran contingent will operate separately from this force, creating overlapping jurisdictions that may complicate coordination on the ground, experts warn.

The new deployment received formal acknowledgment from the Haitian government. Prime Minister Alix Didier Fils-Aime expressed solidarity with the Salvadoran troops and reaffirmed Haiti’s commitment to restoring security in the country. However, analysts note that the Haitian government’s influence over the operation remains unclear, with some suggesting that the mission may represent a form of intervention less constrained by multilateral oversight.

Haiti’s security crisis intensified following the assassination of its last elected president in 2021. Since then, widespread gang violence has surged, with coordinated attacks on government institutions, extensive displacement of civilians, and more than 22,000 recorded killings. Attempts by international forces, including a Kenyan-led police mission and the current U.N. mandate, have failed to significantly restore order.

The abduction of the four Salvadoran soldiers, described as aviation technicians, has heightened tensions. Initial Salvadoran efforts to locate them have not yielded results, contributing to Bukele’s decision to escalate military involvement. The United Nations confirmed that the Salvadoran troops are not integrated into the Gang Suppression Force and did not provide details on their command structure or the expected duration of the deployment.

Critics and observers caution that the operation could exacerbate instability and civilian casualties. Romain Le Cour, director of the Haiti Observatory at the Global Initiative Against Transnational Organized Crime, highlighted the risks of deploying troops with a “no-holds-barred” reputation in a complex conflict environment. Political scientist Robert Fatton Jr. questioned whether the troops could succeed where the U.N. mission has faltered and noted concerns about the Haitian government’s lack of control over these security initiatives.

The Salvadoran deployment marks the country’s largest foreign military operation since the 1969 conflict with Honduras and revives debate over the future of international involvement in Haiti’s ongoing security crisis.
