On January 20, 2025, President Donald Trump issued an executive order signaling an intention to invoke the Alien Enemies Act of 1798 (AEA). This decision represents a significant move within his broader immigration and border security strategy, sparking legal, ethical, and political debates. The AEA, a rarely used law, was originally created during a time of heightened political tensions in the 18th century. It grants the president extraordinary powers to detain, deport, or relocate citizens from countries considered hostile to the United States during declared wars or invasions. The Trump administration’s new angle plans to apply this centuries-old law outside of a formally declared war, marking an unprecedented test of its provisions.
The Alien Enemies Act, signed into law as part of the infamous Alien and Sedition Acts of 1798, was historically applied during wartime and has been dormant for nearly a century. What makes this situation controversial is the lack of a declared war or clearly defined hostile foreign adversary in the traditional sense. Instead, the Trump administration is framing transnational criminal organizations, particularly Mexican drug cartels such as MS-13 and other violent gangs operating along the U.S.-Mexico border, as equivalent to wartime threats. By labeling these groups as Foreign Terrorist Organizations (FTOs) and Specially Designated Global Terrorists (SDGTs), Trump’s executive action seeks to justify detention and deportation measures under the AEA’s provisions.

Key Components of Trump’s Immigration Strategy
This move is not an isolated one. President Trump also signed ancillary orders to bolster his immigration enforcement efforts. These include declaring a national emergency at the U.S.-Mexico border, designating specific criminal organizations like MS-13 and Tren de Aragua as FTOs, and deploying additional resources to enhance border security. In the context of the AEA, these actions are interconnected, creating a legal and operational framework to detain and deport immigrants suspected of connections to designated transnational criminal organizations.
Among the measures announced:
- Deploying 1,500 active-duty military personnel to assist in border enforcement.
- Expanding detention centers to handle a surge in arrests and detentions.
- Enhancing deportation efforts specifically targeting individuals with suspected affiliations to criminal organizations.
On March 1, 2025, the Department of Homeland Security (DHS) revealed the formation of a dedicated task force to operationalize the AEA’s integration into immigration enforcement. This task force has been empowered to coordinate with federal, state, and local law enforcement agencies to investigate, detain, and deport individuals labeled as threats under this policy.
Legal and Ethical Controversies
The decision to apply the Alien Enemies Act without a declared war raises multiple legal hurdles, beginning with constitutional questions. The AEA has long been interpreted as a wartime measure, tied to the presence of enemy nations rather than criminal organizations. Legal experts argue that transnational criminal groups such as MS-13, no matter how dangerous, do not meet the definition of a “hostile foreign government” outlined in the act. In fact, using the AEA for these purposes challenges established principles of due process, which require formal legal proceedings rather than the blanket authority offered by the Act.
“This appears to be an extreme interpretation of the Alien Enemies Act,” said a law professor from Georgetown University. “The AEA grants extraordinary powers but only under specific conditions, namely the existence of a declared war or invasion.”
Challenges to Trump’s plans have already begun to surface. On March 8, 2025, the American Civil Liberties Union (ACLU), with support from immigrant advocacy organizations, filed a federal lawsuit aimed at blocking the policy. The suit claims that the policy’s reliance on the AEA exceeds constitutional limits and violates international law, including protections outlined in various human rights treaties ratified by the United States. The plaintiffs also argue that denying due process as envisioned in this framework sets a dangerous precedent for executive powers and civil liberties.
Other significant legal challenges include:
- Lack of Declared War: Historically, the AEA has been used in wartime against citizens of identified enemy nations. Applying it to criminal organizations with no national affiliation raises questions about the executive branch’s authority under the act.
- Constitutional Protections: Detaining or deporting individuals without legal proceedings opens the door for potential violations of the Fifth Amendment’s protections for due process of law.
- Judicial Resistance: Courts could halt implementation on constitutional grounds, potentially resulting in an unprecedented standoff between the executive and judicial branches.
Opposition and International Reaction
Reaction to the new policy has been swift and polarized. Immigrant rights organizations, including the ACLU, have condemned the plan, citing concerns over human rights violations and racial profiling. Critics also warn of a chilling effect on immigrant communities, where fear might discourage individuals from reporting crimes or seeking assistance from law enforcement.
On the legislative front, Representative Ilhan Omar (D-MN) and Senator Mazie Hirono (D-HI) have reintroduced the Neighbors Not Enemies Act in Congress, aiming to repeal the Alien Enemies Act entirely. This legislation, first proposed in previous sessions but rarely prioritized, carries renewed relevance in the context of Trump’s actions. The proposed repeal seeks to eliminate the AEA as a tool for mass deportations, framing it as outdated and inconsistent with modern legal values.
Internationally, Mexico 🇲🇽 has issued a formal diplomatic protest against the planned application of the AEA, claiming it violates the rights of Mexican nationals residing in the United States. Other Latin American governments are reportedly discussing joint efforts to challenge the policy through international legal channels, potentially involving the Organization of American States (OAS) or the United Nations.
Broader Implications of the Policy
Implementing the Alien Enemies Act under these circumstances could reshape immigration enforcement in the United States. Deportations and detentions related to suspected ties to transnational criminal organizations would likely expand significantly. This escalation carries multiple consequences for both immigrant populations and the broader immigration system.
Potential outcomes include:
- Increased Detentions: Immigrants, including those with legal residency, could face detention based on weak or indirect suspicions of criminal affiliation.
- Expanded Detention Facilities: To handle increased detentions, the federal government will likely need to rapidly build or repurpose facilities near high-immigration zones.
- Citizen and Law Enforcement Tensions: Greater reliance on local law enforcement for immigration activities can create distrust within immigrant communities, disrupting relationships essential for public safety.
- Resource Allocation: Already strained immigration systems—courts, personnel, and detention centers—may find it challenging to cope with such expansive operations.
- Erosion of Rights: The move risks creating a dangerous precedent for eliminating due process protections under the guise of national security.
For those directly impacted by these changes, the stakes are extraordinarily high. Immigrant communities may feel targeted, eroding trust in institutions and prompting fears of indiscriminate action.
Looking Ahead
The Trump administration is clearly intent on moving forward with its plans, despite the looming legal battles and societal backlash. The upcoming months will likely feature intense debates about the limits of executive power, the proper application of immigration law, and the ethical ramifications of policies that blur the line between national security and human rights. As legislative, judicial, and diplomatic challenges gain momentum, the future of the Alien Enemies Act as a viable tool in modern governance remains uncertain.
