Are MS-13, M-18, and Tren de Aragua terrorist organizations? The short answer is no, they are not. They are transnational criminal organizations. El Salvador’s President Bukele and Donald Trump have officially labeled these groups as terrorist organizations, citing their extreme violence and control over some territories. However, these classifications have sparked debate, as their activities are more aligned with organized crime than political terrorism. Making this distinction is crucial given that mislabeling them can lead to misguided policies that fail at curbing their violence.

The 1980s civil wars in Central America forced nearly a million people to flee the U.S. Some immigrants are still forced to leave their countries because of organized crime and gang recruitment. Today most often, some displaced people are victims of gangs, not members or representatives abroad. However, upon originally arriving in Los Angeles, many Central American migrants faced marginalization and sought protection from the gangs present in the areas where they lived and worked. These challenges ultimately contributed to the formation of the present-day MS-13 and M-18 gangs. Many of the members of these new local gangs were incarcerated in Los Angeles prisons alongside members of other gangs, which allowed them to regroup and learn from their rivals. Shortly after the wars, mass deportations from prisons and streets sent MS-13 and M-18 members back to a weakened Central America, where they expanded their networks and influence. 

Similarly, El Tren de Aragua (TdR), which originated in the early 2000s in Venezuelan prisons—particularly the Tocorón prison—has expanded across South America. Originally, a prison gang, Tren de Aragua, expanded beyond prison walls to exploit weak governance, connecting criminal networks across South and North America. Furthermore, like MS-13 and M-18, Tren de Aragua is driven by criminal enterprising rather than political ideology. That is, neither group aims to take over state power or remake society in their own image. Rather, they are hyper-focused on generating maximum profits through illicit means while avoiding state interference. They are criminal syndicates with some capacity—though quite limited—to carry out their rackets across borders. They are certainly NOT terrorist entities. 

What separates a terrorist organization from a criminal syndicate? While both engage in illicit activities and use violence as a means to an end, it is crucial to distinguish their goals and methods to dismantle them effectively. The primary difference lies in their objectives: terrorist organizations seek political, religious, or ideological change by influencing government policies or societal structures, whereas transnational criminal organizations (TCOs) operate across borders solely for financial gain, without political or ideological motives beyond sowing conditions to maximize profit. 

For example, the U.S. government has classified groups like Revolutionary Armed Forces of Colombia (FARC) and ISIS as terrorist organizations due to their political objectives. FARCS’s history dates back to 1964 when it emerged as a communist insurgency that employed terrorist tactics. Initially formed as a guerilla movement from campesino self-defense groups, whose primary objective was to overthrow the Colombian government. Over the next five decades, FARC waged guerilla warfare by carrying out illicit activities—such as bombing, kidnappings, and assassinations–all in an effort to challenge state authority. Colombia, the U.S., and the European Union designated FARC as a terrorist organization due to their use of political violence.

However, the 2016 peace accords between FARC and the Colombian government led to the successful disarmament. This agreement allowed the group to transition into a political party known as Comunes. Even though some dissident factions still operate, FARC’s official transformation has been a key factor in maintaining long-term stability in Colombia. Recognizing this shift has been crucial in fostering peace and ensuring that former combatants can engage in democratic processes rather than armed conflict.

The contrast between ISIS and FARC highlights the importance of proper classification. FARC has abandoned the characteristics that once classified it as a terrorist organization and instead has evolved into a political entity. ISIS, on the other hand, remains committed to its extremist and political ideology, seeking to overthrow governments through guerrilla warfare and establish a global Islamic caliphate through territorial control and sectarian violence. Addressing the causes behind these organizations is equally crucial. FARC’s transition has allowed Colombia to tackle the drivers that led to its rise in the first place, providing the foundation for long-term stability. When governments misdiagnose the factors driving their emergence, violence continues.

Despite claims that Tren de Aragua serves the Maduro regime, evidence suggests otherwise. The group arose from Venezuela’s weak governance and not from direct state sponsorship. According to Insight Crime, in September 2023, Venezuelan law enforcement raided the Tocorón prison in Aragua state, aiming to “dismantle and put an end to organized crime gangs and other criminal networks operating from the Tocorón Penitentiary.” This operation demonstrates that Tren de Aragua is not a state-sponsored group, nor is it a tool being used by the Venezuelan state to destabilize the region. Its rise—like that of MS-13 and M-18—can be traced back to systemic failures, including poverty, corruption, and forced population displacement. These factors have allowed transnational criminal organizations to flourish across Latin America. 

MS-13 and M-18 expanded by exploiting political corruption and institutional weakness in their home countries. Similarly, Tren de Aragua has taken advantage of Venezuela’s economic crises and large emigration to expand into new territories, such as the Darién Gap. Unlike terrorist organizations, these gangs did not emerge to push a political ideology; rather, they have thrived by leveraging corruption and weak law enforcement. In many ways, they are products of the environments that fostered them, growing out of instability rather than ideological ambition.  These transnational criminal groups do not engage in violent attacks abroad, targeting governments or aiming to take political power in the United States. That is beyond their purview and capabilities. 

Why does the distinction between organized crime and terrorist organizations matter? Although all of these organizations engage in violence and illicit activities, their end goals set them apart: MS-13, M-18, and Tren de Aragua operate for profit, whereas ISIS and others seek to reshape the political landscape of their regions. Properly distinguishing between terrorist organizations and transnational criminal organizations like MS-13, M-18, and Tren de Aragua is crucial for drafting effective policies and responses to their violence. Mislabeling these groups can lead to inappropriate responses. Applying counterterrorism measures to profit-driven gangs fails to address the root causes for their expansion in the first place. Failing to properly distinguish organized crime from political terrorists leads to failed policies. The misclassification of these groups could destabilize the region by shifting U.S. foreign policy and resources away from where it is truly needed—addressing the drivers of gang-related violence, corruption, and weak governance—toward counterterrorism efforts. 

While transnational criminal organizations are heavily involved in drug trafficking, and their violence may create fear among civilians and impact governance, this does not qualify them as terrorist organizations. Their primary objective is financial gain, not advancing an ideological or political agenda. This distinction matters because government responses shape outcomes. If the goal is to curb migration, drug trafficking, or violence, then we need to stop treating criminal organizations like terrorist groups and start addressing the real issues driving their expansion. If the U.S. truly wants to curb migration and secure the southern border, then it must ensure that its classification of these organizations is accurate and aligned with its actual objectives.
